ACOTH function

This article describes the formula syntax and usage of the ACOTH function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

Description

Returns the inverse hyperbolic cotangent of a number.

  • 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.
  • This mathematical equation is used:
