Inverse Hyperbolic Secant Calculator

The calculator will find the inverse hyperbolic secant of the given value.

The inverse hyperbolic secant $y=\operatorname{sech}^{-1}(x)$ or $y=\operatorname{asech}(x)$ or $y=\operatorname{arcsech}(x)$ is such a function that $\operatorname{sech}(y)=x$.

It can be expressed in terms of elementary functions: $y=\operatorname{sech}^{-1}(x)=\ln\left(\frac{1}{x}+\sqrt{\frac{1}{x^2}-1}\right)$.

The domain of the inverse hyperbolic secant is $(0,1]$, the range is $[0,\infty)$.

This function is neither even nor odd.
