Definition:Inverse Hyperbolic Cosecant/Real/Definition 1

Definition
The inverse hyperbolic cosecant $operatorname{csch}^{-1}: \R \to \R$ is a real function defined as:


 * $\forall x \in \R: \operatorname{csch}^{-1} \left({x}\right) = \left\{{y \in \R: x = \operatorname{csch} \left({y}\right)}\right\}$

where $\operatorname{csch} \left({y}\right)$ denotes the hyperbolic cosecant function.

Also known as
The inverse hyperbolic cosecant function is also known as the hyperbolic arccosecant function.
