$CosH
Hyperbolic cosine
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $CosH function.
The $CosH function returns the hyperbolic cosine of an argument that is given in radians. If the magnitude of the argument exceeds 175.366, an error message is printed and a 0 is returned.
Syntax
%num = $CosH(x)
