Are you sure of that? I doubt it.

I wonder if he knows that cos tends to go with x and sin tends to go with y wrt a circle and/or ellipse when the angle goes from 0...pi2?
fwiw, an ellipse radii is generally two floating points, x and y. When x is equal to y, its a circle. For some reason, I think of an ellipse as a circle rotated in 3d space. ;^) Try not to flame me too bad? ;^o
