Name
ATANH
Synopsis
Use ATANH to determine the inverse hyperbolic tangent of a number.
To Calculate
=ATANH(Number)-
Number This required argument must specify a number between -1 and 1.
Example
Figure 14-3 illustrates how you can use the hyperbolic functions. Since ATANH is the inverse of TANH, you will notice that the value that is returned by ATANH is equal to the value that was passed to TANH.
