EXAMPLE - Trigonometry Hyperbolic Functions
This example illustrates how to apply hyperbolic trigonometric functions to your transformations. All of the functions take inputs in radians:
Hyperbolic Sine. See SINH Function.
Hyperbolic Cosine. See COSH Function.
Hyperbolic Tangent. See TANH Function.
Hyperbolic Cotangent. Computed as 1/TANH.
Hyperbolic Secant. Computed as 1/COSH.
Hyperbolic Cosecant. Computed as 1/SINH.

In the following sample, input values are in degrees:
X |
|---|
-30 |
0 |
30 |
45 |
60 |
90 |
120 |
135 |
180 |
Transformation:
In this example, all values are rounded to three decimals for clarity.
First, the above values in degrees must be converted to radians.
