While exploring Scherk2 minimal surface, and hyperbola, these shapes came up:

sinhLeaf:
_FxGraph3D u;v;((exp(u) - exp((-1)*u))/2 + (exp(v) - exp((-1)*v))/2);-3.14159;3.14159;-3.14159;3.14159;15;15;0;0;0;UV

sinhcoshScoop:
_FxGraph3D u;v;((exp(u) - exp((-1)*u))/2 + (exp(v) + exp((-1)*v))/2);-3.14159;3.14159;-3.14159;3.14159;15;15;;;;UV

coshBag:
_FxGraph3D u;v;((exp(u) + exp((-1)*u))/2 + (exp(v) + exp((-1)*v))/2);-3.14159;3.14159;-3.14159;3.14159;15;15;;;;UV

The scripts can be stored in a notepad++ text file.

To repeat how to view in MoI, with Max's _FXGraph3D script already installed, highlight one entire line, press Ctrl+C.
Open MoI, press TAB, press Ctrl+V, press Enter.
Network can be used to make a quick surface.
