Inverse Hyperbolic Tangent function plot (Arc hyperbolic tangent, arctanh)
artanh(x) = ln((1 + x) / (1 - x)) / 2
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.
