It seems that one can't plot z as a constant function.
Neither of the following worked:
plot3d([u, v, 2], [u, -3,3],[v, -3,3], ['grid, 30, 30]); or
plot3d( 2, [x, -3,3],[y,-3,3],['grid, 30, 30]);
I also haven't been able to figure out how to plot more than one surface
in the same plot.
Here is a plot I'd like to be able to do:
A single figure showing: the plane 2 units above the xy-plane and
parallel to it, a plane parallel to the xz-plane and 2 units in the
positive y direction, a plane parallel to the yz-plane and 2 units in
the positive x direction and a sphere centered at (3,3,3) with a radius
of one.
Is this possible in maxima?
Again thanks to anyone willing to help.
