Shit.
Clango's punchline came via LadyJ from a few different maths geniuses, but I thought it was wrong, and "fixed it.
In other words, I fucked it up.
It was supposed to be (rhino)(elephant)cos(theta) - apparently this is the forumla for a "cross product", and obviously the source of the joke. I have never heard of a cross product, and figured it was supposed to mean something about the hypotenuse of a right triangle, with the two animals on the othet two sides.
Now I feel like a moron, and LadyJ's maths friends are going berserk. :(
Hari-kiri time, I think.
