A to Z of Excel Functions: the ATANH Function

12 September 2016

Welcome back to our regular A to Z of Excel Functions blog.  Today we look at the ATANH function.

 

The ATANH function

It’s time to talk a complete load of hyperbolics.  The ATANH function returns the inverse hyperbolic tangent of a number (“number”).  This number must be between -1 and 1 (excluding -1 and 1).  The inverse hyperbolic tangent is the value whose hyperbolic tangent is number, so ATANH(TANH(number)) must equal number.

The ATANH function employs the following syntax to operate:

ATANH(number)

The ATANH function contains only one argument:

  • number: this is required and should be any real number between 1 and -1, not including the two extremities.

 Please see my example below:
