Good *ing,
This is a suggestion for William (and/or anyone interested in
developing it... maybe I should try to do it myself, but ;-)
better if someone with more experience tries to).
I think Maxima should have an easy method for plotting para-
metric curves and surfaces..., like
parametricplot2d([3*cosh(t),3*sinh(t)],[t,-2,2]);
to plot a ---guess it--- hyperbola, and
parametricplot3d([cos(theta)*cosh(t),
sin(theta)*sinh(t),t],[t,-3,3],
[theta,-%PI,%PI]);
for a catenoid (?).
I know it could be done using the gnuplot interface, etc... but I
think a straightforward command for omplot (great!) would be best.
Thanks in advance,
Pedro.
