Two points have polar coordinates as follows: θ=130°,r=.35 (point A) and θ=70°,r=.6 (point B). There is a surrounding circle, r=1, that acts as a mirror, and you wish to send a light ray from point A to point B by bouncing it once off the circle. What two alternative directions could you send it in (use an angular measure paralleling the θ coordinate it would have if directed from the origin)?

(In reply to re(4): The objective of the problem by Charlie)

Your calculations are correct SilverKnight, using Charlie´s results. Please, post your final transcient equations and then the final results, I think is fair to also post the final equations of the whole problem, where the angle to be obtained is the only variable in the whole equation. For example: Theta*Sin(Theta)+Theta²*Cos(Theta)=.2 (This is a transcient equation)
