This is fantastic! Thank you very much. I could have really used this
this last semester when I taught multivariable calculus, and I'll
definitely use this this next semester when I teach the same class!
If you have the time or inclination, maybe you could also generalize
this to a cylindrical coordinate plotting function. In fact, I wonder
how easy it would be to make a function that took a coordinate
transformation and gave back a plotting function in those coordinates:
Maybe something like:
def generate_plotting_function(transform):
"""
transform is a list of 3 functions
"""
def new_function(f, var_1, var_2, *args, **kwds):
g=[h(f,var_1,var_2) for h in transform]
parametric_plot3d(g, var_1, var_2, *args, **kwds)
spherical_plot=generate_plotting_function((r*cos(t)*sin(p),
r*sin(t)*sin(p), r*cos(p)))
cylindrical_plot=generate_plotting_function((r*cos(t)*z, r*sin(t)*z, z))
(I'm sure there are errors in the above; I wasn't careful about the
variable names above, for example).
Thanks,
Jason
