Yes, I'm capable of looking them up. I was only pointing out which equations were hit upon during my education. Actually, one thing your post made me realize is that I did touch upon equation 6 in a fourth year algorithms class. I didn't know it as related to polyhedra, as we used it in relation to vertices, edges, and faces in complexity analysis of geometric algorithms.
