Hello, I am wondering if arccoth(x) and arctanh(x) have the same derivatives? I ask this because I got:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\frac{d}{{dx}}arc\coth (x) = \frac{1}{{1 - x^2 }} = \frac{d}{{dx}}\arctan h(x)

[/tex]

I don't think their derivatives should be the same. Does it have anything to do with domain restrictions? Any help appreciated.
