| angle | The REAL radian value for which to find the hyperbolic cosine. |
| Return: | COSH returns a single REAL value. |
The COSH function returns the hyperbolic cosine of the angle.
Example:
Rad2Deg := 57.295779513082; //number of degrees in a radian
Deg2Rad := 0.0174532925199; //number of radians in a degree
Angle45 := 45 * Deg2Rad; //translate 45 degrees into radians
HyperbolicCosine45 := COSH(Angle45);
//get hyperbolic cosine of the 45 degree angle
