Hello, I am wondering if arccoth(x) and arctanh(x) have the same derivatives? I ask this because I got:
[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.
