ATANH

Formulas / ATANH
Calculate the inverse hyperbolic tangent of a number.
ATANH(number)
  • number - a real number between 1 and -1, not including 1 or -1

Examples

  • =ATANH(0.76159416)

    This formula returns 1.00000001, which is the inverse hyperbolic tangent of 0.76159416.

  • =ATANH(-0.1)

    The ATANH function also supports negative numbers. For example, this formula returns -0.100335348, which is the inverse hyperbolic tangent of -0.1.

Summary

The ATANH function calculates the inverse hyperbolic tangent of a real number between -1 and 1, excluding -1 and 1. It requires a number argument to return the result.

  • The ATANH function takes a required real number argument between -1 and 1, but the argument must not be -1 or 1.
  • The ATANH function returns the inverse hyperbolic tangent of the number argument.
  • Note that ATANH(TANH(number)) equals number.
