Math and Trignometric - ACOTH Function

Description

The ACOTH function returns the inverse hyperbolic cotangent of a number.

Syntax

ACOTH (number)

Arguments

Argument Description Required/Optional
Number The absolute value of Number must be greater than 1. i.e., Number must be must be less than -1 or greater than +1. Required

Notes

  • The equation used to calculate the hyperbolic arccotangent is −

    $$a\coth\left ( x \right ) = \frac{1}{2} Ln\frac{\left ( x + 1 \right )}{\left ( x - 1 \right )}$$

  • The hyperbolic arccotangent is an analog of the ordinary (circular) arccotangent.

  • If Number is less than 1, ACOTH returns the #NUM! error value.

  • If the absolute value of Number is less than 1, ACOT returns the #VALUE! error value.

Applicability

Excel 2013, Excel 2016
