🌟 Part 1: Introduction
Definition
The ATANH function in Microsoft Excel returns the inverse hyperbolic tangent of a number.
Purpose
The primary purpose of the ATANH function is to compute the value whose hyperbolic tangent is a given number. In other words, if you apply the ATANH function to the result of the TANH function, you’ll return the original number: ATANH(TANH(number)) equals number.
