Definition of ATANH

Returns the inverse hyperbolic tangent of a number.

Sample Usage





  • value - The value for which to calculate the inverse hyperbolic tangent. Must be between -1 and 1, exclusive.


  • Excellentable does not support imaginary or complex numbers, so these are not valid inputs or outputs from hyperbolic functions.

Step 1: To use the ATANH Formula, simply begin with your edited Excellentable:

Step 2: Then begin typing the ATANH formula in the area you would like to display the outcome: 

By adding the values you would like to calculate, Excellentable generates the outcome:
