# Hyperbolic arc tangent online calculator (inverse hyperbolic tangent)

You can calculate the hyperbolic arc tangent (inverse hyperbolic tangent) of a given number to input the atanh word and numbers in the above form as follows.

In the above example, the calculator shows the hyperbolic arc tangents of -0.7, 0, 0.7, 0.999999. The atanh word works as a command to calculate the hyperbolic arc tangent. All numbers you input should be separated by one space.

Let's input atanh and numbers in the above form!

## Error handling

The hyperbolic arc cosine function is the inverse of hyperbolic tangent so the domain of hyperbolic arc tangent is $(-1,\ 1)$. If you input a number that is smaller than (or equal to) -1 or bigger than (or equal to) 1, the calculator skips.

In this case, -5, 1, 777 are not in the function's domain. The calculator returns only the atanh() of 0.3 and -0.9999.
