Predefined Functions – cotanh

Function name: cotanh – Cotangent hyperbolicus
Synopsis: cotanh(x)


Input data type Output data type
real real
complex complex
quaternion unsupported

Description:

ChaosPro automatically detects the input data type.

In order to calculate cotanh(z) (z = any complex number) ChaosPro performs the following calculation: 

                 sinh(2x)-i*sin(2y)   cotanh(z) = --------------------                 cosh(2x)-cos(2y)

For the definition of sinh(x) and cosh(x) see:
