Talk:List of integrals of inverse hyperbolic functions

Not such a serious error
Note that $$\scriptstyle{\mathrm{arctanh}(y) - \mathrm{arccoth}(y) = (2 n + 1) i \frac{\pi}{2}}$$ (for integer $$\scriptstyle{n}$$). So changing between arctanh and arccoth merely changes the constant of integration. It is true however that arccoth is more appropriate for real arguments greater than one (or less than minus one), since then complex arithmetic is avoided. --catslash (talk) 21:20, 23 September 2013 (UTC)
