Math question of the day: Imagine there's a circular mirror with 2 tiny holes. I put a laser pointer on one of the holes so that after a laser beam will bounce towards the 2nd hole. Derive a formula that will compute "theta" = the angle of the laser pointer relative to the line segment formed by first hole and center, given "phi" = angle formed by the center of the circle and the 2 holes, and n = number of bounces BEFORE reaching the 2nd hole. Illustration of the problem is included.

look at the illustration, get theta given phi and n.

clue from physics:\[\angle _{incidence} = \angle_{reflection}\]
