Purpose:
converts an angle measured in radians to a hyperbolic tangent. (you can convert
the radians to degrees by multiplying them by Math.PI/180)

Syntax:
Tanh(doublenumber)

Parameters Description
doublenumber double percision floating point
number representing an angle measured in radians.

Result Data Type Description
double represents the hyperbolic tangent of the angle specified in
parameter1. If parameter1 is equal to NegativeInfinity,
-1 is returned. If parameter1 is NaN,
NaN (Not a Number) is returned. If parameter1
is PositiveInfinity, +1 is returned.

Quick Example
Tanh(30 * 180 / Math.PI) // Returns 1
