ACOTH
Returns the inverse hyperbolic cotangent of the given number.
Syntax:
ACOTH(number)
- Returns the inverse hyperbolic cotangent of number, in other words the number whose hyperbolic cotangent is number.
- An error results if number is between -1 and 1 inclusive.
Example:
ACOTH(1.1)
- returns the inverse hyperbolic cotangent of 1.1, approximately 1.52226.
