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(2): The objective of the problem
Well... I *think* I did it correctly... and I believe that Charlie verified/confirmed my calculations, but....
I reserve the right to be wrong--in this problem and ALL future ones! :-)
