The inverse hyperbolic cosine function $\mathrm{arccosh}$ is the inverse function of the hyperbolic cosine function. It may be defined by $$\mathrm{arccosh}(z)=\log \left(z + \sqrt{1+z^2} \right),$$ where $\log$ denotes the logarithm.
Graph of $\mathrm{arccos}$ on $[1,10]$.
Domain coloring of $\mathrm{arccosh}$.
