The ACOTH function returns the inverse hyperbolic cotangent of a number.
- This function was introduced in Excel 2013 and so is not available in earlier versions.
|number||The value that you want to calculate the hyperbolic arccotangent of – must be less than -1 or greater than +1, i.e. the absolute value of number must be greater than 1|
|2||=ACOTH(6)||0.168||Returns the hyperbolic arccotangent of 6|
|3||=ACOTH( -5 )||-0.2027||10:33:32|
Common Function Error(s)
|Problem||What went wrong|
|#VALUE!||Occurs if the supplied number argument is not a numeric value|
|#NUM!||Occurs if the supplied number argument is between -1 and +1 (inclusive), i.e, the absolute value of number is ≤ 1|
The hyperbolic arccotangent is the inverse of the hyperbolic cotangent. The equation used to calculate the hyperbolic arccotangent is:
