PREFACE
THE tables in this book present hyperbolic and circular functions of a complex
variable, both in polar and rectangular coordinates. Such complex functions
have not hitherto been published, except over a very restricted range. They have
important applications in electrical engineering. For instance, it is possible with
their help to find in a few minutes the potential, current and power, at any point
of an alternating-current line-conductor of known constants and terminal condi-
tions; whereas the same problem, to a like degree of precision, without aid from
these functions, and by older methods, would probably occupy hours of labor and
cover several sheets of computing-paper.
Although the principal application of these functions at the present time is in
dealing with alternating-current lines, especially those of either great length or
high frequency; yet it seems likely that other uses will develop for them.
The author desires to acknowledge his indebtedness, for suggestions and help,
to a number of workers, both in mathematical and practical fields; and particu-
larly to Messrs. C. L. Bouton, W. Duddell, E. V. Huntington, F. B. Jewett, John
Perry, H. J. Ryan, and E. B. Wilson.

PREFACE TO THE SECOND EDITION
i IN preparing the second edition of this book, six new tables have been computed.
J These are actually extensions of the tables I to VI already incorporated. It has
been considered advisable to add the new material in new tables at the end of the
volume rather than to recast the original tables in such a manner as to include the
new matter. The new matter has been found necessary in certain departments of
electrical engineering to which complex hyperbolic functions may be advanta-
geously applied.

INTRODUCTION
THE Tables in this book are designed primarily for presenting hyperbolic functions
of a complex variable either in the rectangular coordinate form of that variable (x -f- iy)
or the polar coordinate form (p/8). They are also designed secondarily for presenting
circular functions of a complex variable. A few formulas are added as aids to the
conversion of such functions. The most extensive range offered is in Tables VII to
XIV inclusive, between which, the functions sinh (x + iy), cosh (x + iy), tanh (x -f iy),
expressed in the result either in rectangular coordinates u + iv or in polar coordinate
quantities r /y, may be obtained between the limits of o and ± 10 of x, and between the
limits of o and ± « for y. It is shown, moreover, to be an easy matter to extend the
range of x beyond the offered range of ± 10, should such an extension be required.
The practical need for tabulated values of hyperbolic functions of (x + iy) beyond the
range of x = ±10 appears to be so small that any such extension is left to the reader.
As the author's applications for financial assistance in the computation of the Tables
were unsuccessful, the steps in x and y (0.05 and 0.07854 respectively) are larger than
were originally intended; i.e., for reducing the work of the user to the lowest practic-
able limits. Consequently, interpolation must ordinarily be resorted to, when three or
more significant digits are needed in the results. Such interpolations require an appre-
ciable amount of time to effect in two dimensions; i.e., for both x and y. In order to
render such interpolation unnecessary for ordinary engineering purposes, where three, or
at most four, significant digits may be needed, a separate atlas of 23 large-scale charts,
45 cm. X 45 cm. over ruled areas, has been prepared, and is published as an adjunct
to these Tables. The necessary interpolation can very swiftly be made on the charts,
by inspection.
COMPLEX QUANTITIES
The following brief outline of complex quantities is offered in view of their funda-
mental importance in connection with the Tables, for the assistance of those who have
studied elementary mathematics, but who may not have become familiar with com-
plex numbers. For a more comprehensive discussion of complex quantities, the reader
must be referred to special treatises on the subject.
Ordinary numerical quantities, or the numbers dealt with in ordinary arithmetic,
may be considered to range between zero and either positive or negative infinity, by
indefinitely small gradations. Such numbers may be represented geometrically by
distances, in either direction, from a zero point on an infinite straight line. Thus in
Fig. i, we may consider that the straight line — XOX extends from minus infinity on
the left, to plus infinity on the right, O being the zero point. The point x\. would then
represent + i, and so on. That is, the number + i may be regarded as represented
on the line — XOX either by the position of the point xi with respect to the zero point 0;
[153]
EXPLANATORY TEXT
or, as the vector Ox\; i e., the straight line drawn from the origin O to the point x\ and
forming a part of the reference line — XOX. Under these assumptions, the ordinary
numbers of arithmetic may be represented geometrically as vectors; but such vectors
are confined to a single straight-line direction from O towards .X" for positive numbers,
and from O towards — X for negative numbers.
Complex quantities, or complex numbers, cannot be completely represented by
reference to a single direction, or to vectors along one and the same straight line. They
may, however, be represented geometrically by the position, in an infinite plane, of a
movable point with respect to a fixed point as origin. Thus, in Fig. i, the plane XOY
is the plane of reference, and the fixed point 0 is the origin. Then any point PI in the
plane represents a complex number, and any complex number may be represented by
a point on the plane.
-Y
2 X
FIG. 2. — Plane Vector 2.236 e"-106 or
FIG. i. — Complex quantity i + » a. designated by 2.236 763°. 26'.
A complex number may be specified either in rectangular coordinates, or in polar
coordinates, as may be preferred. Thus, the same vector OP\ is represented in Fig. i
to rectangular coordinates, and in Fig. 2 to polar coordinates. In Fig. i, the X axis
— XOX passing through the origin O is the fundamental reference axis, and the Y axis
— YOY, perpendicular thereto in the reference plane, immediately follows. Then the
point Pi, measuring + i along OX, and -f- 2 along OF, may be defined by the expres-
sion (i + 22), where the symbol i signifies measurement along 'the subordinate axis.
It is shown in mathematical treatises that * = V — i. The vector OP\ of Fig. i may
therefore be expressed as (i + V~ 1-2) and a vector from 0 to any point in the plane
may be represented by x + V~i y — x + *3S where x and y may have any positive or
negative numerical values, including zero.
In pursuance of time-honored terminology, the axis — XOX is sometimes called the
"real" axis, and — YOY the "imaginary," axis; so that the ^-component of a
complex number becomes the " real component," and the ^-component the " imaginary
component." The symbol i still stands for the imaginary component. In mathematics
as applied to electrical engineering, the symbol i commonly designates electric current-
strength, and so, in order to prevent the possibility of confusion, the symbol j is
frequently substituted as the sign of the imaginary. Under such a convention, the
plane-vector, or complex quantity, OP\, would be represented as i -\- j 2. As, however,
in this book we necessarily consider complex quantities from a broader viewpoint than
that offered by electrical engineering, we shall use the symbol i to denote the imaginary
component, perpendicularly rotated with respect to the fundamental X axis.
[154]
EXPLANATORY TEXT
Complex quantities may also be expressed in polar coordinates, as in Fig. 2, where
the fundamental reference axis OX is drawn in the positive direction in the reference
plane, from the origin 0, and the circular angle 5i is measured in the positive or counter-
clockwise direction from OX to OP\. The vector OPi is then specified in polar co-
ordinates by its length pi and by its angle 5i. The length p\ is called the modulus of the
vector, and the angle 81 is called the argument. This argument may be expressed in
circular radians, in degrees-minutes-seconds, quadrants, or any other recognized unit
of circular angle. Thus, in Fig. 2, the vector OPi may be represented to polar co-
ordinates symbolically by pi/8\ or, using numbers, by 2. 236/63°. 26', where 2.236 is
the modulus to the same scale of linear measure as in Fig. i, and 63°. 26' is the argument.
If one and the same complex quantity be expressed both in rectangular and polar
coordinates, as follows:
x + iy = p/8 (i)
it is evident that x = p cos 8, y = p sin 5, ;y/a; = tan 8, and p = V x2 + y2, relations which
enable the coordinates to be changed, at will, from one form to the other. ' Thus in
Figs i and 2, xi = i, yi = 2, p\ — VJ = 2.236, and §1 = tan -1 (2) = 63°.26/.

FIG. 3. — Complex quantity — 2 — » i.
FIG. 4. — Plane-Vector 2.236 e*3-608. or 2.236^206^34'.
Similarly, Figs. 3 and 4 represent the complex quantity or plane vector OPi to rec-
tangular and polar coordinates respectively. Here x% = — 2, yz = — i, pz = Vs = 2.236
and 82 = 206°. 34'.
ADDITION OF COMPLEX QUANTITIES
One vector quantity is added to another, by drawing it in the reference plane from
the extremity of the latter as origin, and then drawing a vector from the origin to its

free end. The last named vector is the required sum. Thus, in Fig. 5, the complex
quantity OP2 — — 2 — ii of Fig 3 is added to the complex quantity OP\ =1+12
EXPLANATORY TEXT
of Fig i, giving the resultant vector OP = — i + ii. Fig. 6 shows the corresponding
operation with polar coordinate vectors. Here OP2 = 2. 236/206°. 34' of Fig. 4 is added
to OPi = 2. 236/63°. 26' of Fig. 2, to produce OP = 1.414/135° = p3/8z of Fig. 6.
On the drawing-board, the graphic process of adding vectors is as easily effected
when they are expressed in polar as in rectangular coordinates. But the arithmetical
addition is much more easily made with rectangular coordinates. The rule is: find the
vector sum by taking first the sum of the reals, and then the sum of the imaginaries; or

Reversing the sign of a rectangular complex quantity means reversing the sign of
both its real and imaginary components. Reversing the sign of a polar complex quan-
tity means changing its argument by 180°.
To subtract one complex quantity A from another B, reverse the sign of A, and then
add it thus reversed to B, by the rules of addition.

Here again the process of complex subtraction, which is only a slight modification of
complex addition, is very easily made on the drawing board by purely geometric proc-
esses, whether the quantities are rectangular or polar. If, however, the process is to
be conducted algebraically, it is much more easily conducted with rectangular coordinates.

MULTIPLICATION OF COMPLEX QUANTITIES
Two rectangular complex quantities may be multiplied algebraically by the ordinary
rules of algebra, remembering that i2 = — i. Thus
(*i + fyi) (*2 + iyz) = (xi xz - yi y2) + i(xi y2 + xz yi). (3)
In Fig. 9, the vector OP\ of Figs, i and 2 is multiplied by the vector OP2 of Figs. 3
and 4. The product is the broken line OPz.
For (i + M) X (- 2 - ii) = (- 2 + 2) - i(i + 4) = - *5.

If the two quantities to be multiplied are polar; then
Pi /Si X PZ/SZ = Pi Pz/8i +
(4)
Or the rule is form the product of the moduli and add the arguments. Thus in Fig. 10,
OPi = Vj/63°.26' and OP2 = Vs/2o6^3j/ /. OP3 = 5/27o°.oo/.
RECIPROCAL OF A COMPLEX QUANTITY
The reciprocal of a rectangular complex quantity can be reduced to the standard
algebraic form, by multiplying both numerator and denominator by the same complex
quantity with reversed imaginary. Thus:
i i X (x - iy) _ x - iy _ ( x \ _ .f y \ ,.
1 yt.2 / V /L-2 _J /t«2 / \J/
*2 +
x + iy (x + iy) (x - iy)
For example if x + iy = i + 12,
I _ I /I — J2\ _ !_
1+^2 I + 12 \ I — 12 ) I
—12 I 12
= = 0.2 —

The reciprocal of a polar complex quantity is obtained by taking the reciprocal of
its modulus, and reversing its argument. That is

QUOTIENT OF COMPLEX QUANTITIES
To find the quotient of a complex quantity A divided by another B, form the re-
ciprocal of B and then multiply this reciprocal by A .
Thus to find (x\ + iyi)/(x2 + fy2)
/ x
For example:
\ __ — 2 — ii __ — 2 — ii /i — i:
\ i + *2 i -f- 12 \ i — i'.

= — o.o + i o.o.
Thus, in Fig. 9,
The quotient of two polar complex quantities is formed by taking the quotient of
their moduli and the difference of their arguments. That is

It is thus evident that in order to find either the sums or the differences of complex
quantities, it is desirable to have them expressed in rectangular coordinates; while,
on the other hand, in order to find products, reciprocals, or quotients, it is preferable
to have them expressed in polar coordinates.

POWERS AND ROOTS OF COMPLEX QUANTITIES
It will be evident from the foregoing that
(p/8)n = pn/n8: and \fpjl = y~p/8/n (9)
operations that are readily executed on polar complex quantities.
CIRCULAR AND HYPERBOLIC FUNCTIONS GEOMETRICALLY COMPARED
Since the Tables in this book are adapted for the evaluation of both circular and
hyperbolic functions of a complex variable; that is, either of sin (a; -f- iy), cos (it + iy)
and tan (x + iy); or of sinh (x + iy), cosh (x + iy) and tanh (x + iy), it may be
advisable to consider some propositions in the comparative geometry of the circular
and hyperbolic functions, both real and complex.
REAL CIRCULAR AND HYPERBOLIC FUNCTIONS
The geometry of the real circular functions sin x, cos x and tan x relates, as is well
known, to the motion of a radius vector over a circle. The geometry of the real hyper-
bolic functions sinh x, cosh x and tanh x relates to the motion of a radius vector over a
rectangular hyperbola. In Fig. 12, A b c d E g is a circle x* + y2 = i, assumed to have
unit radius, and center 0. As the radius vector OA rotates in the positive or coun-
terclockwise direction about the center 0, it describes a circular sector such as AOE,
and a circular angle /3, the tangent Ef being always perpendicular to the radius
vector OE. The magnitude of the circular angle /3 may be defined in either of two
ways, namely: —
(1) By the ratio of the circular arc length 5 described during the motion, by the
vector's terminal E, to the constant length p of the radius vector.
(2) By the area of the circular sector AOE swept out by the radius vector during
the motion.
According to definition (i), if the radius vector generates any infinitesimal angle
dfi circular radians, by moving its terminal over an infinitesimally small circular arc ds

If the arc AE1 be measured in the negative or clockwise direction equal in length to the

Turning now to the hyperbolic case, let A b c d E Fig. 13, be an arc of a rectangular
hyperbola x2 — y2 = i, assumed to have unit semi-diameter OA, and center 0. As
the radius vector OA rotates in the positive or counterclockwise direction with center O,
it describes a hyperbolic sector AOE*, and also what may conventionally be called
for convenience a " hyperbolic angle " 0.* The tangent Ef to the path of the moving
terminal E always makes a circular angle /3 with the Y axis; or a circular angle of 2/3
with a perpendicular to the radius vector. The magnitude of the hyperbolic angle 6
may be denned in either of two ways; namely: —
(1) By the ratio of the hyperbolic arc length s described during the motion, by the
terminal E, to the integrated mean length of the varying radius vector.
(2) By the area of the hyperbolic sector AOE Fig. 13, swept out by the radius vector
during the motion. f

finitesimally small angle, whether circular or hyperbolic, is therefore expressed in corre-
ponding radian measure by one and the same term ds/p ; but whereas, in the case of
circular angles, the constancy of the radius vector makes the integral simply s/p, in the
case of hyperbolic angles, the variation of the radius vector makes the integral more
complex. Fig. 14 represents a circular angle of i radian in five sections of 0.2 radian

The sine will be equal to the length of the perpendicular from the terminal of the

The cosine will be equal to the length of the intercept on the X axis made by the

The versed sine will be equal to the length XA, Fig. 12, and A X, Fig. 13, between the
intercept on the X axis, and the horizontal unit radius.

BISECTION or CIRCULAR AND HYPERBOLIC ANGLES
If we take any circular angle BOC Fig. 17, we may of course bisect this angle in either
of two ways: —

Similarly, if we take any hyperbolic angle BDC Fig. 18, between the points B and C
of a rectangular hyperbola, we may bisect this angle in either of two ways: —
(1) By drawing tangents bb, cc, to the curve at the points B, C, respectively, and
drawing the straight line Od from the center O through the point of intersection d.
(2) By drawing the chord, BC, and marking the radius OD through the midpoint

COMPARATIVE GEOMETRY OF COMPLEX CIRCULAR AND HYPERBOLIC FUNCTIONS
We have seen that the real circular functions sin x, cos x, may be derived from a
circle diagram, and that the real hyperbolic functions sinh x, cosh x, may be similarly
derived from a rectangular hyperbola diagram. We shall see that both the complex
circular functions sin (x + iy), cos (x + iy), and the complex hyperbolic functions
sinh (x + iy), cosh (x -\- iy), may be derived from a combination circle and hyperbola
diagram.

DEGREE OF PRECISION OF TABLES
INTRODUCTION
If a numerical quantity, freed from decimals, is correctly expressed to within say
i part in 1000; i.e., i part in io3, then this degree of precision may conveniently be
described as precision of the third order. In general, therefore, if a numerical quantity
be correctly expressed to within i part in ion, where n is any real positive number, its
precision is of the nth order. The weekly statement of the financial assets of a bank
might be expressed as $186,257,361.26 which, assuming that it is to be taken as being
numerically correct to a single cent, represents 18,625,736,126 cents, an apparent
precision of i in lo10'27, or of the 10.2 7th order. Physical and astronomical precisions
are less ostensibly pretentious, however, and rarely exceed the 6th order. Engineering
computations are commonly satisfied with a precision of the third order; although,
on rare occasions, the order required may be the highest that physics can attain.
The degree of precision corresponding to retaining a specified number of significant
digits correct within unity, in Tables, can only be stated approximately ; since it varies
with the values of the digits. Thus, if we have tables containing entries each of three
significant digits, correct to the last digit, the lowest entry may be 100 and the highest
999. The precision would therefore be i in 100 in the former case, and practically i in
1000 in the latter. That is the order of precision would vary between the second and
the third. The average precision might be stated as of the 2. 5th order. Such tables
of n significant digits lay claim to an average precision of the (n — i/2)th order.
Many tables are, however, employed in which the last digit is stated to be correct to
the nearest digit; that is within half of unity. On that understanding, the precision
of say a three-digit table would vary between 1/2 in 100 to 1/2 in 999 or between the
2. 3rd and the 3. 3rd order, with a mean of the 2.8th order. Consequently, we may say
that such tables, giving n significant digits, lay claim to an average precision of the
(n — o.2)th order.
[171]
EXPLANATORY TEXT
DEGREE OF PRECISION PRESENTED IN THE FOLLOWING TABLES
The tables of complex hyperbolic functions here presented have been prvffciied
with a view to giving five decimal places regularly. This means five significant digits
when the values of the results lie between o.i and unity, six significant digits when they
lie between i and 10, four when they lie between o.i and o.oi and so on. Tables I to
VI inclusive were computed with the aid of five-figure logarithms of real hyperbolic
functions, so that their degree of precision is necessarily limited to, and must on the
average fall below that of such logarithm tables, which, as we have seen, is of the 4. 8th
FIG. 25. — sinh (p/5) expressed in polar coordinates.
order. Exclusive of such mistakes as may exist, they do not claim a degree of pre-
cision beyond the 4. 5th order.
Tables VII to XIII inclusive were, however, computed for the most part from Lig-
owski's gudermannian angles which are tabulated by him for each thousandth of a
hyperbolic radian, to the nearest hundredth of a second of circular arc. The logarithms
of the corresponding real hyperbolic functions were then found in the eight-place
tables of Bauschinger and Peters, which offer such logarithms for each and every second
of circular arc. The results were computed in the formulas to at least six significant
[172]
EXPLANATORY TEXT
digits and the sixth was then frequently discarded to meet the needs 9f the five-decimal
table. Consequently in this group of tables, excluding such errors as may exist, the
precision is on the average of the 4.8th order, and rises to the 5. 8th order, when the
value of the result lies between i and 10. The average precision of the second group
of tables is thus about half an order greater than that of the first group.
PRECISION OF THE CHARTS IN THE ATLAS
The charts of the accompanying Atlas have been prepared with a view to offering
three digits in the deduced quantity, if reasonable care be taken in their use. This
represents an average degree of precision of the 2. 5th order; or about equal to that fur-

nished by an ordinary 25 cm. slide rule. When a higher degree of precision than this
is needed, arithmetical interpolation in the Tables must ordinarily be resorted to; but
even then it is desirable to obtain a preliminary approximate value from the Atlas,
in order to furnish a check against gross error.

GRAPHIC REPRESENTATIONS
Figs. 25 and 26 present the results obtained from Table I to true polar coordinates.
Each intersection of the curves corresponds to an entry in the table. Fig. 25 relates
to pages 2, 3, and Fig. 26 to the rest of the table. The curves of constant p intersect
those of constant 5 perpendicularly. That is, each intersection occurs theoretically
at right angles. If, however, an attempt is made to prepare plates corresponding to
Figs. 25 and 26 on a large scale, for a reasonable degree of precision, in rapid interpola-
tion by graphical inspection, difficulties present themselves. Firstly, it has been found
impracticable to procure polar coordinate ruled sheets large enough. Secondly, regular
polar coordinate charts of the type presented in Figs. 25 and 26' necessarily offer very
little graphical interpolation precision at small radial distances from the origin of co-

ordinates, where the radial lines, sharply converging, crowd the diagram. On the
other hand, they offer relatively great apparent interpolation precision at large dis-
tances from the origin, as the radii diverge. In preparing interpolation charts, therefore,
the author has devised the scheme of using squared paper sheets for presenting such
polar coordinate quantities as appear in Figs. 25. and 26. Fig. 27 represents the regular
polar coordinate r/_y_ diagram, in which the lines of constant r are circles concentric
at 0, and the lines of constant 7 are radii diverging from O. Fig. 28 represents the
corresponding squared polar coordinate diagram, in which the lines of constant r are
the vertical straight lines i-i, 2-2, 3-3, and 4-4. The lines of constant 7 are the parallel
horizontal lines, while the origin point O in Fig. 27 becomes expanded into the original
straight line o-o in Fig. 28. The straight, broken line DU is transformed into the
curved line du, and, in general, orthogonally intersecting curves of one diagram do not
transform into orthogonally intersecting curves on the other.
[i74]
EXPLANATORY TEXT
INTERPOLATION CHARTS
Plates IA, IB, and Ic of the Atlas correspond to Table I and present, to squared polar
coordinates, the results in that table. Each intersection of curves in the plates corre-
sponds to one entry in the table. Plate IA includes the entries on pages 2 and 3 of
the table; while Plates IB and Ic include the entries in the remainder of the table.
The curves of constant p and constant 5 intersect one another at various angles, but the
method of interpolation requires little explanation. The entering quantity will fall
within some particular curvilinear parallelogram. The respective opposite sides may
be subdivided into tenths in any of the three following ways: (i) by direct inspectional
estimate, (2) by graphical subdivision on a sheet of tracing paper laid over the chart,
(3) by means of a radiating decimal scale of lines, prepared in advance, on tracing paper
or thin celluloid. It is not, in general, worth the effort of attempting a closer subdivi-
sion than tenths of the sides of any parallelogram. The point of intersection of lines
parallel to the sides, through the correct decimal points, is then to be marked on the
covering tracing paper, or held with a blunt pointer, such as a knitting needle, on the
chart itself, and the rectangular coordinates of this point read off from the parallel
ruling or background of the plate. That is, the charts are always used with the entering
variable on the curvilinear coordinates, and with the result found on the rectilinear frame-
work in the background; except when inverse functions are sought, and the procedure
consequently reversed.

POLAR HYPERBOLIC SINES OF A POLAR VARIABLE
Table I, pages 2 to 7, gives the hyperbolic sine of vectors up to 3.0 in modulus, by
steps of o.i, for each degree of argument from 45° to 90°. The results are also expressed
in polar coordinates, as plane vectors, corresponding to the relation: —
sinh (p/5) = r/7 (30)
or p/d_ = sinh-1 (7/7). (31)
The graphs of the results to true polar coordinates appear in Figs. 25 and 26, where
the curves of constant p always intersect orthogonally the curves of constant d ; so that
at any point of intersection the angles of intersection are right angles. In Plates IA,
IB, and Ic of the Atlas, the same graphs are given to squared polar coordinates, the
disadvantages of the distortion being more than outweighed by the advantages in
facility of graphic interpolation. In these charts the curves of constant p do not inter-
sect the curves of constant 8 orthogonally.

and i. 2136/143°. 005. A first approximation may be obtained by proportional parts
between them, thus : —
Required sinh 2.76/70°
by Table, sinh 2.80/70° = 1.2136/143°. 005.
by Table, sinh 2.70/70° = 1.2031/136°. 489.
Difference 0.10/70° = 0.0105 /6°.5i6.
Proportion for 0.06/70° = 0.0063 /3°.Qio.
sinh 2.70/70° = i. 2031/136°. 489.
Result sinh 2.76/70° = 1.2094/140°. 399.
The true value is 1.2086 /140°.366.
INTERPOLATION BY THE USE OF TAYLOR'S THEOREM
When more precise interpolation is required than that by simple intermediate pro-
portion, we may use Taylor's theorem in the following form; since
-cosh*, =sinh0, etc.
d0
sinh (0 + A0) = sinh 0 + A0 cosh 0 + sinh 0 + - cosh 0 + . . (32)
2!
Let 0 = p/5 and A0 = Ap/5.
Then
sinh \(p + Ap)/« j = sinh (p/6) +Ap/5. cosh (p/5) +~ M sinh (p/3) + . . . (33)
The number of correction terms to be retained depends on the interval, and on the
degree of precision desired. It is seldom that more than two correction terms have to
be retained. Thus in the case already considered: —
sinh (2. 76/70°) = sinh (2. 7/70°) -f- 0.06/70°. cosh (2. 7/70°) +0.0018/140°. sinh(2. 7/70°).
By Table II, page 13, cosh (2.7/70°) = 1.3422/153°. 322. Consequently dealing first
with the first correction term only:
sinh (2.76/70°) = i.203i/i36°.489 + 0.06/70° X 1.3422/153°. 322
= i. 2031/136°. 489 + 0.08053/223°. 322
= i. 2031/136°. 489 (i + 0.066937/86°. 833)
= i. 2031/136°. 489 (i + 0.003698 + i 0.06684)
= i 2031/136°. 489 (i. 00592 /3°.8io)
= i. 2102/140°. 299.
[176]

Taking next the second correction term into account.
sinh (2.76/70°) = i. 2102/140°. 299 -}- 0.0018/140° X i. 203 1/136°. 489
= i. 2102/140°. 299 + 0.002166/276°. 489
= i. 2102/140°. 299 (i -+• 0.001789/136°. 190)
= i. 2102/140°. 299 (i — 0.00129 + i 0.00124)
= i. 2102/140°. 299 (0.99871 -f-io. 00124)
= i. 2102/140°. 299 (0.99871 /o°. 067)
= 1.2086/140°.366.
The correct result is 1.2086/140°.366.

SECOND AND GENERAL CASE. INTERPOLATION BOTH IN MODULUS AND ARGUMENT
Let the entered quantity be sinh (1.025/80.75°).
We have from Table I the four nearest results as follows: —
sinh 1.0/80° = 0.85125/83^.489. sinh 1.1/80° = 0.90416/84^.286.
sinh 1.0/81° = 0.84940/84°. 156. sinh 1.1/81° = 0.90172/84°. 877.
Difference for i° = — 0.00185 + o°.667.
Proportion for 0.75° = — 0.001388 + 0.500.
sinh i. 0/80°. 75 = 0.84986/83°. 989. sinh i.i/8o
sinh i.i /8o.75 = 0.90233/84°. 729.
Difference for o.i = + 0.05247 /o°.74o.
Proportion for 0.025 = + 0.01312 /o°.i85.
sinh i.Q25/8o°.75 = 0.86298/84°. 174.
The true value = 0.863 72/84°. 166.
Diff. for i° = — 0.00244 + o°-59i-
— 0.00183 + 0.443.
= 0.90233
(35)
DUAL INTERPOLATION BY THE USE or TAYLOR'S THEOREM
Let the nearest tabular function be sinh 0 = sinh (p/5_) and the required function
sinh (0 + A0) = sinh | (p + Ap)/d + A8\.
Then (p + Ap) /S + A3 = p/S + (Ap + *PA5). (36)
where the increment Ap + *pA5 is taken with reference to the vector axis p/5. Refer-
ring this increment to the initial axis of reference,
0 + A0 = (p + Ap)/5+AS = p/5 + V(Ap2 + (PA6)2 /& + tan'1 - (37)
/&
So that A0 = V (Ap)2 + (pAS)2 /8 + tan"1 (pA3/Ap). (38)
When, however, A5 is not very small, the last formula may contain an appreciable
error, and the following method of deducing A0, using rectangular complex quantities,
is to be preferred.
[i77]
EXPLANATORY TEXT
Let 0 = p/_8 = x + iy.
and 0 + A0 = (p -f Ap) /8 + A3 = x + A* + * (y + Ay).
Then A0 = A* + i.
(39)
(40)
= V(Aa)2 + (Ay)2 /tan-1 (Ay/As). (41)
We then have by Taylor's theorem, as before,
sinh (0 + A0) = sinh 0 + A0. cosh 0 + - — - . sinh 0 + - — - . cosh 0 + . . . (42)
2 3.2
a series in which two correcting terms only need ordinarily be retained. Thus, in the
example last considered, 0 = 1.0/80° and 0 + A0 = 1.025/80°. 75. If we form A0 by
the use of (37), we have Ap = 0.025, A5 = o°.75 = 0.01309 radian, pA5 = 0.01309.
A0 = V(o-°25)2 + (o.oi309)2 /8o° + tan"1 (0.01309/0.025)
= 0.02822/80° + 27°. 637
= 0.02822 /107°.637.
If we form A0 by the use of the rigid formula (41)
0 + A0 = 1.025/80°. 75 = 0.164761 + i 1.0116715.
0 = 1.0/80° = 0.173648 + ^0.9848078.
A0 = — 0.008887 + 30.0268637
= 0.028295/108° .306.
Entering now the correction formula (42), we find in the tables:
sinh 1.0/80° = 0.85125/83°. 489, cosh 1.0/80° = 0.57991/14°. 521.
so that
sinh 1.025/80°. 75 = sinh 1.0/80° + 0.028295 /io8°.3o6 X cosh 1.0/80°
6
= 0.85125/83°. 489 -fr- 0.028295 /io8°.3o6 X 0.57991/14°. 521

+ o.ooo ooi /324°.9i8 X 0.57991/14°. 521.
It is evident that in conformity with the precision of the tables, only the first two
correction terms need be included. Taking the first into account, we have:
sinh i. 025/80°. 75 = 0.85125/83^.489 + 0.028295/108°. 306 X 0.57991/1.
= 0.85125/83^.489 + o.oi64o8/i22°.827
= 0.85125/83/^489 (i + o.oi9276/39°.338)
= 0.85125/83^.489 (i + 0.014909 + 30.012219)
= 0.85125/83°. 489 (1.014909 + 30.012219)
= 0.85125/83^.489 X i. 01498/0°. 690
= 0.86400/84°. 1 79.
[178]
EXPLANATORY TEXT
Taking up the second correction term: —
sinh 1.025/80°. 75 = 0.86400 784°. 179 + 0.0004003 /2i6°.6i2 X 0.851 25 783°. 489
= 0.86400/84°. 179 + 0.0003405 /3oo°. IQI
= 0.86400/84°. 1 79 (i + 0.000395/215°. 922)
= 0.86400/84°. 1 79 (i — 0.00032 — 20.000232)
= 0.86400/84°. 1 79 (0.99968 — to. 000232)
= 0.86400/84°. 1 79 X 0.99968X0°. 013
= 0.863727 /84°.166.
The true value is 0.86372 /84°.166.
CONCLUSIONS
In general, dual interpolation by simple proportion, as in (35), will give a result of
the third order of precision. In order to secure precision of the fourth order, inter-
polation by the use of Taylor's theorem as in (42) may be required.
EXTENSION or TABLE BY USE or FORMULA FOR 28
Although Table I is only carried as far as 3.0 in modulus (p — 3) ; yet it may be
used with a little additional calculation in conjunction with Table II, for obtaining
the hyp. sines of plane vector quantities of moduli up to 6.0, by means of the formula:
sinh 29 = 2 sinh 0 cosh 6 (43)
Example: Required sinh 5.0/77°, a quantity outside of Table I. Here 6 = 2.5/77°
is within the limits of the Table; so that
sinh 5-0/77° = 2 X sinh 2.5/77° X cosh 2.5/77° (44)
= 2 X 0.87843 /i 20°. 891 X o.96459/i56°.524
= 2 X 0.87843 X 0.96459/277^.415
= 1.75686 X 0.96459/277^.415
= 1. 69465 /277°.41S.
This method ordinarily calls for interpolation both in sinh 6 and cosh 6. For this
reason, it may be preferable to obtain the required result by the use of either Table
VII or Table X, the limits of which are less restricted.
TABLE II
cosh (p/J>) = r[i_
POLAR HYPERBOLIC COSINES OF A POLAR VARIABLE
Table II gives the value of cosh p/5 between the limits of p = o and p = 3.0 by

quantities, to squared polar coordinates, appear in Plates HA and HB of the Atlas.

INTERPOLATION BY SIMPLE PROPORTION
In general, as in the case of Table I, a very fair degree of precision in interpolation
can be obtained by taking first simple proportional parts in argument, and then simple

The correct value is 0.87837 /24.803.
INTERPOLATION OF TAYLOR'S THEOREM
When a higher degree of precision is required than can be expected from simple
proportional parts, we may use Taylor's Theorem in the following form: —

The correct value is 0.87837 /24°.8Q3.
GRAPHICAL INTERPOLATION
For rapid but less precise work, interpolation may be made by proportional parts
on Plate HA or Plate HB, without arithmetical computation.

POLAR HYPERBOLIC TANGENTS OF A POLAR VARIABLE

INTERPOLATION BY SIMPLE PROPORTION
In general, as in the cases of Tables I and II, a very fair degree of precision can be
obtained by taking first simple proportional parts in argument and then simple propor-
tional parts in modulus.

INTERPOLATION BY TAYLOR'S THEOREM
For a higher degree of interpolation precision than by simple proportion, we may
use Taylor's theorem in the following form: —

(A0)3

Ill tanh 0.9/57° = Q.96o56/4i°.o78.
Here A0 = 0.03214/72°. 196, as given by (41). Hence by Taylor's theorem as far as
the second correction term inclusive,

Correct value = 1.0000 /40°.395.
When more than two correction terms have to be retained, it is often easier to deter-
mine sinh (8 + A0) and cosh (6 + A0) by Taylor's theorem, as already described, and
then to take their ratio for tanh (6 + A0).
TABLE IV
sinh 0
POLAR RATIO — - — FOR POLAR VALUES OF 0
v
Table IV has been prepared by dividing the values of sinh 0 found successively in
Table I by their respective values of 0. The object of the table is to facilitate the
computation of the equivalent T or II of any uniform alternating-current line of known
electrical constants.* That is, the table pertains more particularly to the applications
of hyperbolic functions than to the fundamental properties of those functions. The
sinh (p/5)
table gives the vector value of - - for the range p = o to p = 3 by steps of o.i,
p/5
and for 5 = 45° to 5 = 90° by steps of i°. The graphs of the values contained in the
tables are plotted to squared polar coordinates in Charts IVA and IVs of the Atlas, for
rapid graphic interpolation.
INTERPOLATION BY SIMPLE PROPORTION
A fair degree of precision in interpolation can ordinarily be obtained by first taking
simple proportional parts in argument and then simple proportional parts in modulus.

For i. 025/80°. 75 = 0.84247 /3°.424.
Correct value = 0.84265 /3.°416.
When a higher degree of precision is required than can be expected from proportional
parts, the proper value of sinh (6 + A0) should be obtained by Taylor's theorem as
already explained in connection with Table I, and this value divided by (6 + Ad) ;
because the expansion of — , . directly, by Taylor's theorem, does not lend itself
conveniently for computation.
EXTENSION FOR THE RANGE OF THE TABLE BY THE USE OF FORMULA FOR 26
Although Table IV is only carried as far as 3.0 in modulus (p = 3); yet it may be
used with a little additional calculation, in conjunction with Table II, for obtaining
— — , for vector values of 6 with moduli up to 6.0, by means of the formula: —
a
sinh 26 = 2 sinh 6. cosh 6 (47)
sinh 26 sinh 6
whence — - — = — - — . cosh 6. (48)

multiply the result by the hyperbolic cosine of the quantity as obtained from Table II.
Corresponding steps may be taken with Charts II and IV.

it may be preferable to obtain the required result by the use of either Table VII or
Table X, the limits of which are less restricted.
TABLE V
tanh 6
POLAR RATIO — - — FOR POLAR VALUES OF 0
u
Table V, like Table IV, has been prepared for electrical engineering applications of
hyperbolic functions, rather than for developing these functions alone. It gives the
tanh (p/6)
vector value of
p/5
for the range p — o to p = 3.0 in modulus, by steps of o.i,
and for the range 5 = 45° to 8 = 90° in argument, by steps of i°. It was computed
directly from Table III by dividing the resulting values successively by their respec-
tive values of 6. The graphs of the values in Table V are presented to squared polar
coordinates in Chart V, for rapid graphic interpolation.
INTERPOLATION BY SIMPLE PROPORTION
Except where a high degree of precision in interpolation is required, it is prefer-
able to interpolate first by simple proportion in argument, and then by simple pro-
portion in modulus; although this order of operations may be inverted.

EXPLANATORY TEXT
When a higher degree of precision is needed than simple proportion can give, it is
preferable to find the proper interpolated value for tanh Q from preceding tables and
then to divide by 0; since the function - -. — — r — does not lend itself to expansion
(0 + A0)
by Taylor's theorem in a simple form.
Tables IV and V jointly, with their respective graphs in the Atlas, enable the equiva-
lent T or II of any uniform alternating-current line in the steady state, at a single fre-
quency, to be completely determined, provided 0 does not exceed six radians in modulus
(5 lying between 45° and 90°) ; because although in both tables, 0 is not carried beyond
three radians; yet — — — can be found by extension up to six radians, and in the formu-
0
las for deducing the equivalent T or II, — - — - has only to be carried to half the modulus
0
, sinh 0
of-0-'
The following example may illustrate the use of Tables IV and V either with or
without the aid of the graphic interpolation Charts IV and V of the Atlas. An alter-
nating-current line of uniform electrical constants is 250 km. long and has, at a certain
frequency, a total conductor impedance of 565.711 784°. 777 ohms, associated with a
total distributed insulation admittance of 4.3707 X io~3/9o° mhos. Its hyperbolic
angle is therefore Vs. 65711 X 4.3707 X io~1/i74 .777 = 1.5724 787°. 388 hyperbolic
radians. Interpolating either from the tables or the Charts IV and V, we obtain
sinh0 .tanh () tanh 0.7862/87^88
= 0.638 /
. _ 0.786a/8
If we multiply the conductor impedance by — - — , we have
u
565. 711 784°. 777 X 0.638/2°. 6 = 360.69/87°. 377 ohms, and if we multiply half the
insulation admittance by — ff). g , we have
Iff/
2.1854 X io-3/9o° X i.27\i°.5 = 2.78 X io-3/88°.g mhos = 359-77\88°.5 ohms.
If now we apply an artificial condenser leak of 2.78 X io-y88°.5 mhos to each end of a
localised impedance coil of 3 60. 6 9/87^.3^7 ohms, we obtain the "equivalent II" of the
line at the frequency considered, and such a combination of localised impedance and ad-
mittances would behave exactly like the line, at its terminals, or outside them, so as to
be capable of replacing the line in any electrical system, at that frequency.

TABLE VI
POLAR FUNCTIONS OF POLAR SEMI-IMAGINARY QUANTITIES
A semi-imaginary quantity is a complex numerical quantity which, when expressed
in rectangular coordinates, has equal real and imaginary components; or, when ex-
pressed in polar coordinates, has an argument of 45°. That is x/± 45° = a rt i a.
The interest of the table pertains primarily to the application of hyperbolic functions
to uniform alternating-current lines of negligibly small linear inductance and leakance,
a case approximated to by cabled lines at low frequencies. The table was first pub-
lished by the author in the transactions of the International Electrical Congress of
St. Louis (1904). The arguments of the results are given in degrees and minutes, and
not in degrees and decimals like the rest of the tables.
The table gives the hyperbolic sine, cosine, tangent, cosecant, secant, and cotangent
of the vector x/4$° for the range x = o to x '= 20.5, by steps in x of o.i up to x = 6,
and of 0.05 beyond that point. At x = 6, the values of the hyp. sine and cosine so
nearly coincide, that they are taken as equal in the table, thus bringing sech x and
cosech x into equality as well as tanh x = coth x = i. Graphs of the functions are
given in Chart VI as far as x = 4, approximately.
INTERPOLATION BY SIMPLE PROPORTION
In general, interpolation may be quickly effected by simple proportional parts of
modulus since the argument is constant at 45°. This procedure is sufficiently evident
to require no exemplification.
INTERPOLATION OF TAYLOR'S THEOREM
When precise interpolation is necessary, we have the following expansions for
f (0 + A0)
sinh (* + A*) /4S! = sinh (2/45°) + (Ax) /4S°. cosh (*/45°) +
sinh (*/45°) + -=r/ilS°. cosh (*/45°) + ..... (49)

Example: Required cosh (3.1/45°), having given in Table VI

cosh (3. 0/45°) = 4-U43 /i22°.i6/.

= 4.I443/I22°.33' X 1.0760 /3°.42;
which is in substantial agreement with the tabulated value of cosh 3.1.
Beyond x = 6, the value of either sinh (3/45°) or cosh (#/45!) was computed from
the formula: —
sinh (s/45°) = cosh (s/45°) = J — /T/T radians. (52)
v ^
where e = 2.71828 . . .

Thus, with x = 7, — T= = 4.9498, - = - = 70.57 at the argument of 4.9498 cir-
\j 2 ^2
cular radians = 283°. 36'; so that: —
sinh (7/45°) = cosh (7/4.5!) = 7Q.57/283°.36/
which coincides with the tabulated value in Table VI.
TABLE VII

RECTANGULAR HYPERBOLIC SINES OF A RECTANGULAR VARIABLE
Tables I to VI contain certain restrictions in range which limit their general appli-
cation. They are primarily designed to cover particular applications of hyperbolic
functions to electrical engineering. Tables VII to XIV, however, are free from such
restrictions, and are intended to furnish the circular as well as the hyperbolic sine, cosine,
and tangent of a complex angle, and to furnish this result either in the rectangular or
polar form. That is, they furnish: —

between the limits, for the hyperbolic functions, x = o and x = ± 10, by steps of 0.05
and between the limits y = o and y = ± oc , by steps of 0.07854 = TT/^O.
PERIODIC PROPERTIES OF THE RECTANGULAR COMPLEX HYPERBOLIC
SINES AND COSINES
It is well known that sinh \x + i (y -f 2mr)\ = sinh \x + iy\ (53)
and cosh \x + i (y + 2mr) \ = cosh \x + iy\ (54)
where n is any integer.
This means that, keeping x constant, the values of the hyp. sine and hyp. cosine
repeat themselves as iy passes through increments of i.2ir\ or they are periodic functions
of iy, having the period 2ir i.
The matter may be visualised more clearly from geometrical reasoning. Consider-
ing the exponential form of the hyperbolic cosine,
c * + 'V _L e -<* + '»)
cosh (x + iy) =- — — . (55)
e* . e~1
This may written in the form: — . e iy -\ e~iv. If x be kept constant, we
require to study the changes produced in this form of the hyp. cosine by varying y.

FIG. 29. — Geometrical constructions for cosh (x + iy) and sinh (* + iy).
In Fig. 29, OA is an initial line and OP a radius vector of length or modulus €*/2>
multiplied by e '»; that is rotated positively about O, from OA through a circular angle
of y radians. Similarly, op is a vector of length or modulus €~*/2 rotated negatively
through a circular angle of y radians from the initial line Oa. The equation (55) states
that the hyperbolic cosine is the plane vector sum of OP and op, or O'p' in the Figure.
If now we steadily increase the value of y, leaving x constant, we cause OP to rotate
steadily counterclockwise, and also op to rotate steadily clockwise, through Ay cir-
cular radians. When Ay = 2ir, both OP and op will have made one complete revo-
lution and will have returned to their initial positions indicated. Consequently, the
value of cosh \x + i (y + 271-) \ repeats that of cosh \x + iy \.
€ x + iy _ f -(x + iy)
Since sinh (x + iy) = - (56)
the same reasoning applies; but the vector op is added in the negative or reversed di-
rection; so that O'q' is the hyperbolic sine of x + iy.
The above mentioned periodic property of the hyp. sine and cosine has been utilized
for shortening the tables of those functions by reducing the circular angle y of Fig. 29
[189]
EXPLANATORY TEXT
from radians to quadrants. That is, any complex angle x + iy represented by a point
P, and radius vector OP, in the complex plane XY, Fig. 30, is first transferred to a
new complex plane XQ, Fig. 31, at the point p = x, q, by keeping x the same in both
planes, but making the points -, — ,—,—,... etc., on the Y axis of the XY diagram,
2222
become the points i, 2, 3, 4 ... etc., on the Q axis of the XQ diagram. Thus if
x + iy = 2.5 + * 6. 2832,
x + iq = 2.5 + i 4.00
where 4.00 is underscored to indicate quadrant measure, instead of the ordinary radian
measure.

FIG. .30.
FIG 3r.
Transference of a Complex Quantity from the XY to the XQ Plane.
In the case indicated by Fig. 30, x + iy = 3 + i 9 and x + iq — 3 + * 5.74 in Fig. 31.
Consequently, after a complex angle has been transferred from the complex plane
XY to the complex plane XQ, the values of either sinh (x + iq) or cosh (x + iq) exactly
repeat themselves for each 4 units of increase in q; or with reference to Fig. 31 for each
4 quadrants of increase in the circular angle instead of 6.2832 . . . radians. The
operation of transferring the complex angle from the XY to the XQ plane may there-
fore be described as quadranting y; i.e., changing the expression of y from circular
radian units to circular quadrant units.
All of the Tables VII to XIII inclusive require to be entered in terms of x + iq;
so that the complex entering value has to be quadranted by dividing its imaginary or
y-component by the numeric v/2 = 1.57079 This preliminary step occupies
a certain extra time and effort; but it actually economises the total time and effort
involved. If the tables were computed for x -f- iy, they would have to be repeated in
bulk for each TT radians, or 2 quadrants, increase in y. In electrical engineering appli-
[ 190]
EXPLANATORY TEXT
cations, y frequently rises to 100 radians, and might easily be much greater than 100.
In order to go up to 100 radians, the bulk of the Tables VII to XIII would have to be
increased about thirty fold. Altogether, aside from the greatly increased bulk and expense
of such tables, the extra time and effort consumed in turning over the numerous pages
would be comparable with that saved by eliminating the preliminary step of quadranting
the imaginary component or dividing it by ir/2.
RULES FOR THE USE OF TABLE VII
Express the " angle " whose hyperbolic sine is required in the form of an ordinary
rectangular complex quantity x + iy.
Quadrant the imaginary component y through the process of dividing it by ir/2;
i.e., transfer the quantity from the XY to XQ plane; so that the new expression of the
complex quantity is x + iq; where q = y/i. 57079. . . .
If q is greater than 4.6, divide by 4 and retain«only the remainder. If the remainder
exceeds 2, subtract 2 therefrom, and apply a negative sign to the result found in the
table. A change of 2 quadrants simply reverses the sign of the result. If the remainder
on the other hand does not exceed 2, enter Table VII with it, and take out the result
with unchanged sign.
• Example: Required the hyperbolic sine of 0.65 + i 25.75. Here x = 0.65 and
y = 25.75. That is y is 25.75 circular radians. Reduce this to quadrants through
dividing by 1.57079. . . .
25-75 * log 25.75 = 1.4107772.
1.57079 ... log TT/2 = 0.1961199.
log 16.393 = 1.2146573.
The quadranted yalue x + iq = 0.65 + i 16.393
NOTE. — It is found convenient to underscore quadrantal quantities to distinguish
them from radianal quantities.
Rejecting quadrant multiples of 4, i.e., 16 in this case, we enter Table VII with
x -|- iq = 0.65 + i 0.393. The nearest entry to this is x = 0.65, q = 0.4, for which
the hyperbolic sine is 0.56368 + * 0.71639, an ordinary rectangular complex quantity
on the U V plane. Interpolation should be made in this result to meet the change
from q = 0.40 to q = 0.393, as wiH De explained later.
Second Example: Required sinh (x + iy) = sinh (1.15 + i 10.10).
. / . 10.10 \
Quadranting the imaginary, sinh (x + iq) = sinh ( 1.15 + * = 1
= sinh (1.15 + i 6.430).
Rejecting 4'$ from the imaginary = sinh (1.15 + i 2.430).
Deducting 2 from the residual and chang-
ing the sign = — sinh (1.15 -f *'o-43°)-
* This operation would ordinarily be effected with the slide-rule, when a high degree of precision is not
aimed at.
[191]
EXPLANATORY TEXT
We now enter Table VII with x = 1.15 and q = 0.43. The nearest entry is x = 1.15
q = 0.45, the result for which is 1.08037 + * 1.12836. But we must apply a negative
sign to the whole of this result because of the 2 rejected in the quadrantal residuum.
Hence,
sinh (1.15 + i 10. 10) = — (1.08037 + * 1-12836)
= — 1.08037 — i 1.12836 = u + i v
except for the interpolation from q = 0.45 to q = 0.43. The operation of interpolation
will be discussed later on.
Third Example: Required sinh (x + iy) = sinh (3.60 + i 18.1).
Quadranting the imaginary, sinh (x + iq) = sinh ( 3.60 + i— '—^ }
* \ i-57°<V
= sinh (3.60 + i 11.523).
Rejecting 4'$ from the quadrants = sinh (3.60 + ^'3.523).
Deducting 2 from the residual imaginary
and changing the sign .............. = — sinh (3.60 + i 1.523).
Entering Table VII with x = 3.6 and q = 1.523, the nearest entry is x = 3.6 and
q = 1.5, for which the result is — 12.92978 + * 12.94910. But applying the negative
sign to this result because of 2 deducted from the quadrantal imaginary, and we have
finally: —
sinh (3.60 -+- i 18.1) = — (— 12.92978 + i 12.94910)
= 12.92978 — i 12.94910 = u + i v
except for the interpolated correction from q = 1.500 to q = 1.523, to be considered
later.
RANGE OF THE TABLE
Table VII extends by steps of 0.05 in x up to x = 3.95, and in Table XIII up to
x = 4.0. In y, the range is indefinitely great; because after dividing y by ir/2 so as
to reduce it to quadrant measure, all multiples of 4 are rejected. From o to 2, in the
remainder, the table gives the result directly and from 2 to 4, by change of sign in the
total. Cases of x greater than 4.0 are dealt with in connection with Table XIV.
REPETITIONS IN THE TABLE
If sinh { x + i- — a = u + iv (57)
I \2 / )
it is easy to show that:
sinh I * -M ( - + 0 ) \ = — u + iv. (58)
I \2 / J
It follows that in any column of Table VII, the entry for q = (i — a) is the same as
that for q = i + a except for a change in the sign of u. Consequently, the table might
have been reduced to half its present size, if the responsibility for making this change of
sign had been left to the reader. It was considered, however, that since the reader is al-
ready charged with the duty of applying a negative sign to the total result when the q
[ 192]
EXPLANATORY TEXT
residuum lies between 2 and 4, the retention of the full size of the present table was
warranted, especially as the duplication of the text in each column provides a certain
check upon the numerical work of tabulation.
INTERPOLATION BY SIMPLE PROPORTION
As a first approximation, interpolation may be effected by simple proportion, first
in regard to x and second in regard to q.
Example: Required sinh (0.15 -f 3*0.25), having given:
sinh (0.2 -f 3*0.2) = 0.19148 + 3*0.31522. sinh (0.2 + i 0.3) = 0.17939 + 3*0.46310.
sinh (o.i + 3*0.2) = 0.09526 + 3*0.31056. sinh (o.i + 3*0.3) = 0.08925 + 3*0.45626.
Diff. for o.i x = 0.09622 + 3*0.00466. Diff. for o.ix = 0.09014 -f- 3*0.00684.
Diff. for 0.052; = 0.04811 + 3*0.00233. Diff. for 0.052; = 0.04507 + 3*0.00342.
sinh (0.15 + i 0.3) = 0.13432 + 3*0.45968.
sinh (0.15 + 3*0.2) = 0.14337 H~ * 0.31289. sinh (0.15 + 3*0.2) = 0.14337 -f- 3*0.31289.
Diff. for q o.io = — 0.00905 + 3*0.14679.
Diff. for q 0.05 = — 0.00453 + i 0.07340.
sinh (0.15 + 3*0.25) = 0.13885 + 3*0.38629.
Correct value = 0.13910 + 3*0.38700.
INTERPOLATION BY TAYLOR'S THEOREM
When a higher degree of precision is desired than that which can be expected by
simple proportion, we may use Taylor's theorem in the following form: —
sinh (0 + A0) = sinh 0 + A0 cosh 0 + ^- sinh 0 + z=f- cosh 0 + . . . (59)
sinh { (x + iy) + (Ax + i Ay) \ = sinh (x + iy) -f- (Ax + i Ay) cosh (x + iy)

cosh(o.i + 3*0.2) = 0.95582 + i 0.03095. Then by (60);

EFFECTS OF CHANGES OF SIGN IN THE ENTERING QUANTITY
Table VII expresses the relation
sinh (x + iq) = u + iv. (63)
(a) If x be taken with negative sign, we have
sinh (— x + iq) = — u + iv (64)
so that changing the sign of the real component entering the table changes the sign of
the real component in the result; but leaves the sign of the imaginary component
unchanged.
(b) If q be taken with negative sign, we have
sinh (x — iq) = u — iv (65)
so that changing the sign of the imaginary component in the entering quantity changes
the sign of the imaginary component in the result, leaving the sign of the real com-
ponent unchanged.
•
(c) If both x and q be taken with negative sign, we have
sinh (— x — iq) = sinh \ — (x + iq) \ = — u — iv = — (u + «0 (66)
so that changing the sign of the total entering quantity changes the sign of the total
result.
The facts may be summed up by saying that changes in the sign of the entering
quantity produce corresponding changes of sign in the result.

CIRCULAR SINES OF COMPLEX " ANGLES "
Since, as is well known: —
sin 6 = — i sinh (iff) (67)
we have
sin (x + iy) = — i sinh (ix — y) (68)
= * sinh (y — ix). (69)
Consequently, in order to find the circular sine of the complex quantity (x + iy), enter
Table VII for sinh (y + ix), which on being quadranted, becomes sinh \ y + ix/(ir/2) \
and let the result be (u + iv). Then sinh (y — ix) = u — iv and sin (x + iy) = v + iu.
In other words, invert the entering components, and then invert the components of the
result.
Example: Required sin (i + i 2) from Table VII. Here 6 = (i + i 2).
Enter the Table with — sinh (id) = sinh (— id) = sinh (2 — i i).
Quadranting the imaginary, we enter the table with (x — iq) = (2 — i 0.6366).
The nearest entry is (2 — i 0.65), for which the hyp. sine is given as 1.89503 — i 3.20780.
Consequently, sin (i + i 2) = 3.2078 -f- i 1.89503, except in so far as interpolation is
needed to reduce sinh (2 — i 0.6366) from sinh (2 — 3' 0.65). In this way any circular
sine of a complex quantity can always be obtained from the table of hyperbolic sines,
between the limits of o and ± 4 in y, and of o and ± °o in x.
GRAPHIC INTERPOLATION BY MEANS OF CHARTS VIlA, Vila, VIIc
Charts VII-VIII A, B, and c, serve for the evaluation of either sinh (x + iq) or
cosh (x + iq), according to the axis of reference selected. Thus, taking Chart VII-
VIIIs, if this is held with the. line SS as the axis of reference or initial line; then by
comparison with the entries in Table VII, it will be found that sinh (x + iq) can be
read from it directly over the range q = o to q = 4, beyond which the values repeat
themselves indefinitely. On the other hand, if the chart be turned through 90°, so
as to bring the line CC as the axis of reference, it will be found by comparison with the
entries of Table VIII, that cosh (x + iq) can be read from it directly over the range
q = o to q = 4.
Chart VII-VIIlA gives sinh (x + iq) and cosh (x + iq) for values of x up to about
0.9. Chart VII-VIIIs gives the corresponding results for values of x up to about
x = 2. Finally, Chart VII-VIIIc provides for values of x up to x = 4. In all of
these charts, interpolation can be made for both x and q to o.oi, by direct inspection.
The graphs on these charts are undistorted, since they give complex functions as results,
in rectangular coordinates. The curves therefore always intersect orthogonally, and
they represent a confocal system of ellipses and hyperbolas, the common foci being at
two points at unit distances from the center, along one of the reference axes. The curvi-
linear rectangles into which the charts are divided have pairs of sides the ratio of
whose lengths tends to the value ir/2.
If the preliminary process of quadranting the imaginary of the entering quantity
were not adopted; that is, if the graphs were entered in terms of (x + iy), instead of
[196]
EXPLANATORY TEXT
(* + iq) ; then it would be necessary* to have a new chart for each range of 2ir units in
3>; or some 16 sets of Charts A, B, and C, in order to reach y = 100. That is, 48 charts
would have to be computed, prepared, drawn, lithographed, bound, sold and operated
instead of the 3 charts actually presented. Moreover, if y were needed greater than
100, the set of 48 would fail; whereas, working with quadrant imaginaries, the three
charts serve up to indefinitely great values of q and y,
GRAPHIC CHART VII-VIIlA
This chart corresponds to Tables VII and VIII at least as far as x = 0.9, or for
pages 42 to 45, and 58 to 61 of this book. To find hyperbolic sines from the chart,
place it facing the observer with the axis OO vertical. This is the major axis of all the
ellipses shown. Starting from this central axis towards the right hand, the successive
ellipses marked o.i, 0.2, 0.3, etc., represent values of x; while the successively rising
hyperbolas o.i, 0.2, represent values of q. These values of q will be found to extend
over two quadrants. Enter the chart on the curvilinear coordinates for x and q. At
the proper intersection read off the u and v coordinates of the rectilinear ruling, u being
the abscissas and v the ordinates.
Conversely, to find sinh"1 (u + iv) within the limits u = o and « = ±i,»=oto
v = 2.0, enter the chart with the same aspect on the rectilinearly ruled coordinates
and read off at the proper intersection the curvilinear values taking x on the ellipses
and q on the hyperbolas.
To find hyperbolic cosines from the chart, rotate it clockwise 90°; so as to have
the axis OO horizontal. Then enter on the curvilinear coordinates with x on the ellipses
and q on the hyperbolas. The first and fourth quadrants only will be presented to the
observer; but from the symmetry of the diagram, it will be easy to reverse the chart,
so as to present the second and third quadrants. Read off the result on the rectilinear
background using u for abscissas and v for ordinates.
Conversely, to find cosh"1 (u + iv) from the chart with the axis OO horizontal, enter
on the rectilinear background and read off at the proper intersection from the curvilinear
coordinates in x and q, taking the ellipses as parts of the it-system and the hyperbolas
as part of the ^-system.
GRAPHIC CHART VII-VIIIs
This chart gives the graph of the functions sinh (x + iq) and cosh (x + iq) from
x = 0.8 at least as far as x = 2.05 along the ellipses and from q = o to q = °o by virtue
of successive rotations. In this and the following charts, the numerical values of q are
all underscored, an indication which may serve readily to distinguish the imaginaries
q, from the reals, x.
* A single set of charts entered in terms of (x + iy) could be used up to y — 6.2832 in one revolution,
and could be used for all larger values by throwing out multiples of 2*-. This operation of dividing y by 2T
would, however, take as much time as the operation of quadranting, and would also lead to a dissymmetrical
chart in the hyperbolas.
EXPLANATORY TEXT
In all of the Charts VII to IX inclusive, the curvilinear rectangles all tend to have
sides in the ratio TT : 2; that is the long side approximates to being 1.57 times the short
side. In IXA exceptions are found; because extra curvilinear coordinates are supplied.
To find sinh (x + iq) from Chart VII-VIIlB, hold the minor axis 55 horizontal.
Enter on the curvilinear coordinates with x on ellipses and g on hyperbolas. At the
proper intersection read off on the rectilinear background in u and v. Proceed inversely
to find the inverse function sinh"1 (u + iv).
To find cosh (x + iq) from the same chart, hold the major axis CC horizontal. Enter
on the curvilinear coordinates with x on ellipses and q on hyperbolas. Read off on the
rectilinear background.
All four quadrants appear in this and the following chart, so that it is not necessary
to limit the value of q to less than 2 quadrants.
GRAPHIC CHART VII-VIIIc
This Chart gives the graph of sinh (x + iq) and cosh (x + iq) from x = 2.0, at least
as far as x = 3.90. The procedure is precisely the same as that for VII-VIIlB already
described.
TABLE VIII
cosh (x + iq) = « + iv
RECTANGULAR HYPERBOLIC COSINES or A RECTANGULAR VARIABLE
Table VIII may be regarded as an inversion of Table VII; because:
cosh 6 = — i sinh (6 + iir/z) (70)
or in quadrant imaginaries,
cosh 6 = — i sinh (6 + i i). (71)
That is the hyp. cosine of any complex quantity (x + iq) is — i times the hyp. sine
of that quantity with an additional quadrant in the imaginary. Thus
cosh (0.5 + io,6) = — isinh (0.5 + i 1.6)
= — * (— 0.42158 + 20.66280)
= + 0.66280 + * 0.42158.
All of the entries in Table VII thus reproduce themselves by inversion in corresponding
parts of Table VIII, a fact which serves as a numerical check upon both.
In order to find the value of cosh (x + iy), quadrant the imaginary quantity y, by
dividing it with IT/ 2, as in entering Table VII. The complex quantity (x + iy) will
now be expressed as (x -\- iq); or will in effect have been transferred from the XY to
the XQ plane. Next throw out multiples of 4 from q, so as to leave a remainder less
than 4. If this remainder exceeds 2, deduct 2 from it, but change the sign of the total
result thereupon deduced. • If the remainder, however, is not greater than 2, then,
the result is taken directly from the table.
Example: To find cosh (1+25 ) = cosh (x + iy).
Quadranting, we have cosh (i + 13.183) = cosh (x + iq).
Deducting 2 from q, cosh (i + i 1.183).
[198]
EXPLANATORY TEXT
With this we enter Table VIII. The nearest entry is x + iq = i +^1^2, the result
for which is — 0.47684 + i 1.11768. This has to be corrected by interpolation from
q = 1.2 to q = 1.183. Reverse the sign of the result to 0.47684 — i 1.11768 for the
deduction of 2 quadrants.
Example 2: Required cosh (0.25 + 2*30 ) = cosh (x + iy).
Quadranting, this becomes cosh (0.25 + i 19.099) = cosh (x + iq).
Rejecting imaginary quadruples = cosh (0.25 + 2*3.099)
= cosh (x + iq).
Deducting 2 quadrants = cosh (0.25 + i 1.099)
= — cosh (x + iq).
The nearest entry is 0.25 + ii.i for which the result is (— 0.16135 + * 0.24950).
Applying the negative sign on account of the two deducted quadrants, the final result
is, neglecting interpolation,
cosh (0.25 + i 30) = 0.16135 ~~ * o-2495o = u — iv.
INTERPOLATION BY SIMPLE PROPORTION
A first approximation can be obtained by interpolating according to simple pro-
portion.
Example: Required cosh (0.55 + 2*0.55) = cosh (x + iq)
having given
cosh (0.6 + 20.5) = 0.83825 + i 0.45018. cosh (0.6 + i 0.6) = 0.69680 + 10.51506.
cosh (0.5 + 2*0.5) = 0.79735 + i 0.36847. cosh (0.5 + 20.6) = 0.66280 + 2*0.42158.

Diff. for x 0.05 = 0.02045 ~l~ 20.04086. Diff. for x 0.05 = 0.01700 + 2*0.04674.
cosh (0.55 + i 0.6) = 0.67980 + 20.46832.
cosh (o.55 + 2o.jj) = 0.81780 + 20.40933. cosh (0.55 + 2*0.5) = 0.81780 + 10.40933.
Diff. for q cxi = —0.13800 + 2*0.05899.
Diff. for (70.05 = —0.06900 + 2*0.02950.
cosh (0.55 + 2*0.55) = 0.74880 + 20.43883.
Correct value = 0.75018 + * 0.43963.
INTERPOLATION BY TAYLOR'S THEOREM
For a higher degree of precision than simple proportion affords, reference may be
had to Taylor's theorem in the following form : —
cosh (6 + A0) = cosh 6 + A0 sinh Q + - cosh 6 + sinh 0 + . . .

= 0.73233 + 3*0.39624.
The tabulated value = 0.73233 + « 0.39624.
In view of the similarity of the interpolation operations by Taylor's theorem to
those already discussed in relation to Table VII, further examples are probably not
needed.
EFFECTS OF CHANGES OF SIGN IN THE ENTERING QUANTITY
Since if cosh ( x + iy) = u + iv (72)
cosh (— x + iy} = u — iv (73)
cosh ( x — iy) = u — iv (74)
cosh (— x — iy) = u + iv (75)
changing the 'sign of either the real or imaginary entering component only changes the
sign of the imaginary component in the result; while changing the sign of the enter-
ing quantity as a whole, has no effect on the sign of the result.

CIRCULAR COSINES OF COMPLEX " ANGLES "
It is well known that if 6 be any angle, real or complex,
cos 6 = cosh (i6). (76)
Consequently,
cos (x + iy) = cosh (— y -f ix) (77)
or, quadranting the imaginary component,
cos (x + iy) = cosh (— y -f- i 2x/ir) = u + iv. (78)
To find the circular cosine of any complex quantity x + iy, we enter Table VIII
with (— y -f * x/ 1. 5 708). The result is the desired cosine.
Example: Required cos (0.4 + i 1.2).
Thus we require cosh (— 1.2 + i 0.2546).
We now enter Table VIII with x = — 1.2 and q = 0.2546 the nearest entry being
x = — 1.2 and q = 0.25, for which the result is 1.67283 — * 0.57765.
Hence cos (0.4 + * 1.2) = 1.67283 — i 0.57765 neglecting interpolation from q = 0.25
to q = 0.2546.
GRAPHIC CHART INTERPOLATIONS

been described in connection with sines, on pages 197-198.

RECTANGULAR HYPERBOLIC TANGENTS OF A RECTANGULAR VARIABLE
Entering Process
Let tanh (x + iy} be the required function. Quadrant the imaginary component,
as described under Tables VII and VIII; that is, divide y by IT/ 2; so that y/(*/2) — q.
The required function is now expressed in the form tanh (x + iq). Throw out mul-
tiples of 2 from q and retain only the remainder as q. Enter Table IX with (x + iq),
and find the result directly as u ± iv. It is a well-known property of tanh (x + iy),
that it is periodic in iy, and that the period is i.ir circular radians; or, in quadrants,
i.2. That is
tanh I x + * (y -f mr) \ = tanh (x + iy). (79)
where n is any integer; or, in quadrant measure of the imaginary,
tanh \ x + i (q + 2n) j = tanh (x + iq). (80)
Example: Required tanh (0.25 + *3o) = tanh (x + iy).
Quadranting, tanh (0.25 + i 19.099) = tanh (x + iq).
Rejecting multiples of 2, tanh (0.25 + i 1.099) = tan^ (x + *'?)•
We now enter Table IX with x = 0.25 and q = 1.099, the nearest entry to which
x = 0.25, q = i.i. The result is 2.95122 — i 1.75011.

Interpolation may be approximately effected by simple proportion, first in x and then
in q, as indicated in connection with Tables VII and VIII; or, when a higher degree of

The correct value is 0.84752 + * 0.71229.
As the third correction term is inconvenient for computation, it is often preferable
to obtain a precise interpolation of tanh (x + iy) in working out the correct inter-
polations of sinh (x + iy) and cosh (x + iy) by the methods already illustrated, and
then to take their ratio.

EFFECTS OF CHANGES OF SIGN IN THE ENTERING QUANTITY
If tanh ( x + iy) u + iv (86)
then tanh ( x — iy) = u — iv (87)
tanh (— x + iy) = — u + iv (88)
and tanh (— x — iy) = — (u + iv). (89)
Consequently, changes in the sign of the entering quantity produce corresponding changes
of sign in the result.

= — i (— u + iv)
= v + iu. (92)
Consequently, to find tan (x — iy) from Table IX, enter it with y as x and with x/(ir/2)
as q. Invert the components of the result and the required function is obtained. Thus

required tan (i+ 2* 2). We enter with x = 2 and q = 0.6366. The nearest entry is
x — 2.0 and q = 0.65 for which u + iv = 1.01623 + i 0.03318. Therefore, inverting,
tan (i + i 2) = 0.03318 + i 1.01623
neglecting the interpolation from q = 0.65 to q = 0.6366.
GRAPHIC INTERPOLATION BY MEANS or CHARTS IXA, IXs, AND IXc
These charts contain all of the entries in Table IX, and also a certain number of
additional results. They present circles intersecting circles orthotomically; i.e., by
rectangular intersection. It is clear that for values of x less than o.io, the curves run
off Chart IXA. In fact the first curve shown of x = o.oi extends as far as u = 100.
By taking x small enough, the corresponding values of u and v may become indefinitely
great. The entire UV plane is covered to infinity once between x = o and x = o°,
q = o and q = ^ It is covered once more for each 2 quadrants increase in q.
When entering for tanh (— x ± iq); or for the inverse operation tanh"1 (— u ± »),
it must be remembered that the confocal conic-section diagrams VII and VIII
are complete for negative as well as for positive values of x and q; but that only half
of the UV plane is presented in Charts IX. The full graph is indicated in Fig. 32,
by the aid of which the functions corresponding to negative real values are readily
apprehended.
TABLE X

POLAR HYPERBOLIC SINES or A RECTANGULAR VARIABLE
This table corresponds completely to Table VII, already considered, except that it
offers results in polar instead of rectangular coordinates.
To find sinh (x + iy) expressed in polar coordinates, quadrant the imaginary, and
express the entering variable as (x + iq). Reject multiples of 4 in q, and if the re-
mainder exceeds 2, reject 2 but change the sign of the total result.

INTERPOLATION BY CHARTS X-XlA AND X-XIs
These charts present the polar coordinate results on rectangular coordinate sheets,
so that they are not true graphs, but are merely to be regarded as interpolation dia-
grams.
To find sinh (x + fy), proceed as in the use of the tables and quadrant the imaginary
so as to obtain the entering quantity in the form (x + iq}> Enter with the curvilinear
coordinates, taking the more nearly vertical wavy lines for x and the more nearly hori-
zontal lines for q, starting from the line SS as the zero of q. Read off the result on
the rectangular background to the left-hand scale of ordinates.
When we leave X-XlA and enter X-XlB,it is noticeable that the curves of constant
x approach vertical straight lines and the curves of constant q approach horizontal
straight lines. At and beyond x = 3.0, we may approximate to the modulus r at any
required q, by taking the value of r at q = 0.5 and simple proportional parts between
this and r at q = o or r at q = i.o. The change in modulus r between q = 0.5, and
either of the above limits is very nearly e~z/2- Thus at x = 3.5 and q = 0.5, r by the
tables is 16.55774. At q = o, r = 16.54263, a change of — 0.01511, and at q = i.o
r = 16.57282, a change of + 0.01508. The value of c~3-6/2 will be found to be 0.01510,
and over the entire range of q from o to i.o, the change in r follows in nearly simple
proportion.
Beyond x = 3.2, the limit of Chart X-XIs, the values of r can be obtained
by the above rule applied to Table X and with the aid of Chart VII-VIIIc. The
values of the amplitude y beyond x = 3 closely approximate to q quadrants. That
tx
is sinh (x -f- iq) approximates to — ^£, with q in quadrant measure.
TABLE XI
cosh (x -\- iq) — * /7
POLAR HYPERBOLIC COSINES OF A RECTANGULAR VARIABLE
Table XI corresponds completely with Table VIII, except that it gives results
expressed in polar instead of rectangular coordinates. It is entered with (x -f iq} just
as in Table VIII.
[205]
Interpolation may be effected by simple proportion, as in the case of Table X, or
when a higher degree of precision is required, it may be carried on by Taylor's theorem.
In the latter case, it is more convenient to refer to the corresponding entries in Table
VIII, interpolating according to formula (716). The rectangular coordinates duly
interpolated are then transformed into polar coordinates, as in the last example on
page 225.
INTERPOLATION BY CHARTS X-XlA AND X-XIs
When Charts X-XI are used to find cosh (x + iy) , the imaginary is first quadranted
by dividing with ?r/2, so as to obtain the entering variable in the form cosh (x + iq).
Starting then from q = o at the horizontal line CC, near the middle of the chart, the
underscored figures correspond to q for a little more than the first quadrant. The
manifest repetition of the curves enables the lower half of the sheet, however, to be
used for the second quadrant. The result is read off on the rectangular background
to the right-hand scale of argument.
Beyond x = 3.2, the limit of Chart X-XlB reference may be had to Chart VII-
VIIlB; or the approximate formula may be used:
ex
cosh (x + iq} = — /£. (93)

degrees.
TABLE XII
tanh (x + iq) = r /y
POLAR HYPERBOLIC TANGENTS OF A RECTANGULAR VARIABLE
Table XII corresponds completely with Table IX, except that it gives results
expressed in polar instead of rectangular coordinates.
If we desire to find tanh (x + iy), we must first divide y by IT/ 2 so as to obtain the
entering quantity in the form (x + iq). Multiples of 2 are then rejected in q leaving
a remainder less than 2. With this remainder the table is entered.
Interpolation may be made by simple proportion to a moderate degree of precision.
GRAPHIC INTERPOLATION BY MEANS OF CHARTS XIlA, B, c, D
These charts cover between them the full range of Table XII. To find tanh (x + iq)
from them with q less than 2, find the proper chart, and enter orr'the curvilinear co-
ordinates keeping the underscored number for q. Read off the result on the rectilinear
background.
For tan (x + iy) and also for the effects of changes of sign, see directions in the dis-
cussion on Table IX.
To find tanh""1 (r/r), enter immediately on the rectangular background of r and 7
in the proper chart, and read off at the correct intersection the corresponding values
on the curvilinear coordinates. The result will appear in terms of (x + iq). The
imaginary q must be dequadranted, or multiplied by 7r/2, in order to be expressed in
terms of (x + iy).
[ 206]

TABLE XIII
/ (4 + iq) = u + iv or r /y
RECTANGULAR AND POLAR FUNCTIONS OF THE RECTANGULAR VARIABLE (4 + iq)
In this table the hyperbolic sine, cosine and tangent of (4 + iq) are collected from
q — o to q = 2.0. The results are expressed both in rectangular coordinates (u + iv),
and in polar coordinates r /y.
It will be seen that the moduli of the tangents vary between 0.99933 and 1.00067,
or differ from unity by two thirds of one per mil, at most. The arguments also differ
from o° by less than 0.04°, or about 2'. 17" of arc.
Beyond x = 4, it is evident that the hyp. sine and cosine differ by so small a per-
centage, that no tabulation of these differences would ordinarily be required.
TABLE XIV
e*/2 and log 10 (ex/2)
SEMI-EXPONENTIALS
This table enables the hyp. sine or cosine of any rectangular variable (x + iq) to
be found for values of x greater than 4 and less than 10. It is shown in the preceding
table that when x reaches 4, the ratio of the sine to the cosine never differs from unity
by more than two-thirds of i per mil. This deviation from unity rapidly diminishes as
x is further increased. Consequently, the sine and cosine may each be computed from
the formula.
sinh (x + iq) = cosh (x -f- iq) = — /q. (94)
Example: Required the value of sinh (8.51 -f- i 25.75). The first step is to quad-
rant the imaginary by dividing with x/2, as on page 191. This gives the required func-
tion in the form sinh (8.51 + i 16.393). Rejecting multiples of 4.0 in q, we may then
write it sinh (8.51 + 3*0.393). Turning to the top of page 143, we find ex/2 = 2482.082
for x = 8.51; so that the result is 2482.082 70.393 quadra-nt. Expressing the argument
in .degrees by multiplying with 90 and we have 0.393 X 90 = 35.37°. Thus
sinh (8.51 + i 16.393) = cosh (8.51 + i 16.393) = 2482.082 /35°.37.

it follows that when Ax is a small quantity, it suffices to multiply the tabular value of

correction term, is of sufficient magnitude to need consideration.

REAL HYPERBOLIC FUNCTIONS
This is a short table of real, as distinguished from complex hyperbolic functions for
convenience of reference. It was prepared and published by the author in 1903 in re-
lation to continuous-current electric circuit applications, taking the sines, cosines, and
tangents from Ligowski's tables, and adding the corresponding computed reciprocals
for the cosecants, secants, and cotangents. Much more extensive tables of real hyper-
bolic functions are, however, available. See Bibliography, page 211.
TABLE XVI
SUBDIVISIONS or A DEGREE
This is a short table for convenience in changing the expression of a circular angle
from decimals of a degree to minutes and seconds, or inversely. By its aid, three-
decimal subdivisions of a degree may be converted into minutes and seconds of arc, by
direct inspection; or minutes and seconds may be read off as decimals of a degree ta
three-digit accuracy.
METHODS EMPLOYED IN COMPUTATION
Tables I to V, inclusive, were computed as one group, and Tables VII to XIII,
inclusive, as a separate group.
Tables I to V were computed, at first, by using the formulas: —
sinh (x + iy) = V sinh2 x + sin2 y /tan"1 (tan y / tanh x) = ri /yi. (96)
cosh (x + iy) = Vcosh2# — sin2;y /tan"1 (tan y • tanh x) = r2 /72. (97)
tanh (x + iy) = (ri/r2) /TI ~ 72- (98)
At a later stage of the work, the following formulas, kindly suggested by Professor
Bouton, were substituted: —
sinh (x + iy) = Vcosh 2X • sin z /tan"1 (tan y / tanh x) = ri fji. (99)
cosh (x + iy) = V cosh sx • cos z /tan"1 (tan y • tanh x) = r% /jz. (100)
tanh (x + iy) = tan z /y\ — 72- (101)
[208]
EXPLANATORY TEXT
Where the auxiliary circular angle z is defined by :
cos 2y
- = COS 2Z. (102)
cosh 2X
The arithmetical work was conducted with the aid of five-place logarithms, and was
checked by tabulating successive first and second differences in the tabulated results.
Tables VII to XII were computed by means of the following formulas: —
sinh (x + iy) = sinh x cos y -f- i cosh x sin y. (103)
cosh (x -f- iy) = cosh x cos y + * sinh x sin y. (104)
, f . . sinh 2X sin 2y
tanh (x + ty) = — r- — - -f * — — — ^ (105)
cosh 2# -f cos 2y cosh 2* + cos 2y
A standard schedule was prepared and seven-place logarithms used in the compu-
tation. The value of tanh (x + iy) was arrived at in two ways, first by dividing (103)
by (104), and second by the independent formula (105). If these two methods did not
give identical results for tanh (x -f- iy) to five decimal places, when expressed both in
rectangular and polar coordinates, the steps of the computation were gone over afresh.*
Complete agreement being secured, leads to the inference that the values of sinh, cosh,
and tanh (x + iy) are correct, at least as far as their logarithms.
Finally, all of the tables have been reduced to graphic form in the Atlas, each entry
of the tables being marked off on its proper chart with a sharp needle, and the ruling
pen drawn through the successive punctures. In this process a certain number of
errors were discovered and rectified. The tables were then set up in type from the
MSS. used in making the charts, and were proofread three times. By this procedure
it is hoped that the outstanding errors are neither large nor numerous.
BIBLIOGRAPHY AND APPLICATIONS OF HYPERBOLIC FUNCTIONS
Hyperbolic functions of a real variable are employed extensively in mathematics
generally. In particular, they are used in the solution of cubic equations.
In navigation, real hyperbolic functions enter in connection with Mercator sailing.
In cartography, real hyperbolic functions are used in preparing maps on certain pro-
jections, especially on Mercator's projection, which appears to have been the first
application of hyperbolic functions.
In statics, real hyperbolic functions naturally present themselves in relation to the
properties of the catenary and of the funicular polygon; also in the discussion of the
forms and stresses of elastic bodies.
In dynamics, the same functions present themselves in the theory of vibrations,
and in the motion of bodies through a resisting medium.

EXPLANATORY TEXT
A good summary of the historical development of real hyperbolic functions is given
in Becker and van Orstrand's "Hyperbolic Functions," Smithsonian Mathematical
Tables, 1909, together with a fine compendium of formulas involving these functions.*
In electrical engineering, the earliest published application of real hyperbolic func-
tions is perhaps in T. H. Blakesley's "Alternating Currents of Electricity," London,
1889, which also appends a short table of these (real) functions. The real functions
were also introduced by Sir J. J. Thomson, in "The Electrician," Vol. XXVIII, page
599, 1891. "On the Heat Produced by Eddy Currents in an Iron Plate Exposed to an
Alternating Magnetic Field."
The fundamental differential equation of the alternating potential-current, steady-
state distribution along a uniform conductor, involving hyperbolic functions, nominally
real, seems to have been first published by O. Heaviside in 1893, "Electromagnetic
Theory," Vol. I, page 450.
The first published application of complex hyperbolic functions to the last-named
problem was by the author, "On the Fall of Pressure in Long-Distance Alternating-
Current Conductors," Electrical World, N. Y., Vol. XXIII, page 17, January, 1894
and "The Electrician," London (abstract), Vol. XXXII, page 239, January 5, 1894.
Complex hyperbolic functions also present themselves in the discussion of Hertzian-
wave reflections, and in other branches of electrical engineering. They naturally enter
the subject of confocal ellipses and hyperbolas, such as Captain Weir's Azimuth diagram
of these confocals, for indicating the azimuth of a celestial object in terms of the hour-
angle, latitude and declination. (Godfray's "Astronomy," § 222.)
The mathematical discussion of hyperbolic functions is found in GreenhilTs "Differ-
ential and Integral Calculus," Macmillan and Co., 1896; Ligowski's "Tafeln der Hyper-
belfunctionen und der Kreisfunctionen," Berlin, Ernst & Korn, 1890; McMahon's
"Hyperbolic Functions," Wiley and Sons, N. Y., 1896; Becker and van Orstrand's
"Hyperbolic Functions," Smithsonian Institution, 1909; Vassall's "Nouvelles Tables
des Logarithmes," Paris, Gauthier-Villars, 1872; as well as other text-books.

are: "The Application of Hyperbolic Functions to Electrical Engineering Problems,"

of Electrical Currents in Telephone and Telegraph Conductors," Constable & Co.,

of this volume.
NEW TABLES INTRODUCED IN THE SECOND EDITION
Tables I to V in this volume were computed for the range of 45° to 90° in the slope
or argument 5 of the entering vector quantity; because at that time it did not appear
that there would be any need for the range from o° to 45°. Alternating-current lines
used for the transmission or distribution of power have linear hyperbolic angles a, the
slope of which is commonly between 80° and 90°, rarely falling as low as 45°. It has
been shown during recent years, however, that railway-signal engineers employ track-
signaling circuits, formed of the rails. These are metallic circuits of low frequency,
small linear capacitance and large distributed linear leakance. The linear hyperbolic
angles a of such circuits develop slopes lying within the range 5 = o° to 45°. It has
therefore become desirable to cover this range, at least as far as p = i. For that pur-
pose, Tables XVII to XXI have been inserted. They run by steps of 0.05 in p, from
o to i.o, and by steps of 5° in 5, from o° to 45°. This new tabulated material is
available for use in track-signaling and similar computations. It is hoped to incorpo-
rate it graphically into the associated Chart Atlas at the first opportunity.
Table XVII presents sinh p/£ as a polar planevector. It corresponds to and may
be regarded as an extension of Table I. Similarly Tables XVIII, XLX, XX and XXI
correspond respectively to Tables II, III, IV and V. Whereas, however, Tables I to V
are carried to five decimal places in the sizes and three decimal places in the slopes of
the evaluated quantities, the new tables are carried to six decimal places in sizes and
four decimal places in slopes. They thus aim at one higher order of precision.*
Table XXII is similar to Table XI and expands the region covered by the first six
entries of the latter into a correspondingly magnified field. It has been found that in

dealing with short lengths of alternating-current line, having negligible linear induc-
tance as well as negligible linear leakance, and therefore having a semi-imaginary linear
angle, there is frequent need for a magnified table of this kind. It may be noted that
whereas Table VI expresses slopes in degrees and minutes, Table XXII expresses them
as degrees, and four-place decimals of a degree.
Table XXIII is a useful collection of 238 formulas, with a few insertions, taken
from Becker and van Orstrand's book of Tables of real hyperbolic functions, referred to
