Often you want to avoid explicit trig calculations. They are complex, slow, and introduce rounding errors. So having a way to think about trig that avoids them is useful.

But push come to shove, there is inherent complexity that you aren't going to get around.

Cheers,
Ben

New Seems to me ...
Trig is based on measurements of the triangle itself: what is the length of each side, what are the angles, etc. This method seems to enable doing formulas directly on the coordinates. I could be mis-reading -- okay, I didn't read the whole thing -- but that's what it looked like.
