comment How elliptic arc can be represented by cubic Bézier curve?
+1. I wish I had seen this post earlier. I've recently implemented circular arcs in PostScript.

comment Intuition for Absorption and Distributive Laws in Elementary Logic
I suspect you may be throwing yourself off track with the "or all three" part in both of your attempts. For (AL1), there are only 2 terms.

comment Intersect a line with a bicubic Bezier Surface Patch.
Thanks. I'll check those out. I also stumbled across this: Implicitization and parametrization of quadratic and cubic surfaces by μ-bases which looks pertinent.

This really does appear to be the right answer both popularly and pragmatically, so I accept. I'm not giving up, but it's going to take me some time to understand Kajiya. First surprise is his use of homogeneous coordinates, so I'm going back to Maxwell for background, and I found a pdf of Modern Higher Algebra, by George Salmon, 1885, from wikipedia.
