I have two Mathematica questions for the assembled multitudes.
(1) I would like to take two quadric surfaces, e.g. two paraboloids
8-(x^2)-(y^2),(x^2)+3(y^2), graph the two together AND Then
graph the intersection on the xy plane "below" the two surfaces.
In general, how do we get the surfaces to "cast a shadow".
(2) Even if I calculate the intersection of the above myself,
(x^2)+2(y^2)=4, how can I get Mma to graph this. In general,
how do we graph functions expressed implicitly?
Thanks,
