The ATANH function returns inverse hyperbolic tangent of the given number. Inverse hyperbolic tangent is nothing but a value and its hyperbolic tangent is a number.
Whereas "Number" is the value whose inverse hyperbolic tangent has to be found. It should be between -1 and 1.
Let us find the inverse hyperbolic tangent value of the given number, using the ATANH function, with the help of the below video.
