Well once you get air resistance (which is significant with these) along with any spin, those equations don't quite cut it; some sort of expirementation and creating just an n-th order polynomial approximation might be better (that maps some parameters [distance, angle of camera, power, whatevever] to angle).

Anyhow, my TI-89 doesn't give me anything for those equations so perhaps if I have time in a little bit, I'll solve it by hand.
