1. ## Help with hyperbolic cotangent

I need some serious help solving for x in terms of known mathematical constants on this one:

$xln(2pi)=arctan(coth(((x(pi))/2))$

Good luck

take the tangent of both sides and then use identities, I do not think it will be that bad.

I know about that, but I cannot find anywhere on the web that gives me an identitiy relating coth and tangent like that. Think you could help me out there?

I would suggest convertin it into its exponential form.
