User:Thyg/Scherk's second surface

Scherk's second surface is the minimal surface defined by the equation $$\sinh x \, \sinh y = \sin z$$. It is the conjugate surface to Scherk's first surface.

Scherk's second surface has Weierstraß-Enneper representation thus $$ p = \frac{1}{1 - z^4} $$, $$ q = z\,\! $$.
