Returns the acoth of x to a multiple of eps with error less in

acoth(x) = ln((x + 1)/(x - 1))/2 is the real number v for which
coth(v) = x.
acoth(x) is the real number v for which coth(v) = x.
It is given by
acoth(x) = ln((x + 1)/(x - 1))/2
EXAMPLE
> print acoth(2, 1e-5), acoth(2, 1e-10), acoth(2, 1e-15), acoth(2, 1e-20)
