Inverse Hyperbolic Cosine function plot (Arc hyperbolic cosine, arccosh)
arcosh(x) = ln(x + sqrt(x^2 - 1))
Plotted with cubic bezier-curves. The bezier-controll-points are calculated to give a very accurate result.
Asymptotes are included but commented out.

Symbols are embeded in "Computer Modern" (TeX) font.
