coth(x)

Input: x · Output: no output

What it is

The other three hyperbolics: coth(x) = cosh(x)/sinh(x), sech(x) = 1/cosh(x), csch(x) = 1/sinh(x). x is a real number or Complex. coth/csch have a pole at x=0 (and, for a Complex argument, at every x = i*k*pi) — evaluating there is an error, not a silent inf/NaN. sech has no real pole (cosh is never zero).
