I think I figured out plane-plane and quadric-quadric intersections, but if Astner or someone would like to clarify for me...
Well plane-plane interactions are going to produce lines.
So, there is going to be some line that satisfies both equations at once. Converting to Cartesian coordinates usually worked for me because I was good with fractions and hate trig.
Spherical is also useful, though? I mean, like, the thing you are learning about was probably taught to you just a couple days ago. Read your notes and go to class!
