Description

This function is used to return the inverse hyperbolic cosecant.

Syntax

 double acsch(double x)

Parameters

x is any real number except 0, which returns missing value. Note that any number whose absolute value is greater than ~3E153 is computationally out of bounds and will also return missing value.

Return

Return the inverse hyperbolic cosecant of that number.

Example

dd=acsch(-10);
dd=; //Should return -0.0998.
