Cosh

Function: cosh (<x>) - Hyperbolic Cosine.

x(u,v):=1/cosh(u)*cos(v);
y(u,v):=1/cosh(u)*sin(v);
z(u,v):=1/cosh(u)*sinh(u);
plot3d([x(u,v),y(u,v),z(u,v)], [u,-0.5*%pi,1*%pi], [v,0*%pi,1.95*%pi], [grid,50,20],[palette,get_plot_option(palette,3)]);

There are also some inexact matches for cosh. Try ?? cosh to see them.
