Textbook Problem

Let *P*(*x*_{1}, *y*_{1}) be a point on the ellipse *x*^{2}/*a*^{2} + *y*^{2}/*b*^{2} = 1 with foci *F*_{1} and *F*_{2} and let *α* and *β* be the angles between the lines *PF*_{1}, *PF*_{2} and the ellipse as shown in the figure. Prove that *α* = *β*. This explains how whispering galleries and lithotripsy work. Sound coming from one focus is reflected and passes through the other focus. [*Hint:* Use the formula in Problem 17 on page 201 to show that tan *α* = tan *β*.]
