## What is the atanh or inverse hyperbolic tangent?

Inverse hyperbolic tangent is the inverse of the hyperbolic tangent, which is the hyperbolic sine over the hyperbolic cosine. It can also be written using the natural logarithm:

arctanh(x)=\frac{\ln(\frac{1+x}{1-x})}{2}

### Arctanh as a formula

Inverse hyperbolic tangent is often written as arctanh, but usually abbreviated as "atanh" or "artanh", as in the following equation:

arctanh(y) = atanh(y) = artanh(y)

Where it is the inverse of hyperbolic tangent, or:

x=arctanh(y)\\y=tanh(x)
