Is there a way to prove this algebraically without the use of calculus? And without resorting to 3d visual demos, which have caused me more confusion than clarity.

If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.

I think he meant a geometric proof. Like, with the pythagorean theorem. There are "proofs" that show that the pythagorean theorem is indeed correct. -shrug- Poly might know. |
