Acsch
Acsch-func
Description
This function is used to return the inverse hyperbolic cosecant.
Syntax
double acsch(double x)
Parameters
x
- 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.
