Purpose:
takes an angle specified in radians (to convert degrees to
radians multiply degrees by 180/Math.PI) and returns the hyperbolic
cosine for the angle as a double data type.

Syntax:
Cosh(doublenumber)

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

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

Quick Example
Cosh(90) // Returns 6.1020164715892E+38
