In Exercises 60 and 61 we ask you to prove Theorem 9.23 for ellipses and hyperbolas

Consider the ellipse with equation $\frac{x^{2}}{A^{2}} + \frac{y^{2}}{B^{2}} = 1$ where $A > B$ . Let $F$ be the focus with coordinates $(\sqrt{A^{2} - B^{2}}, 0)$ . Let $e = \frac{\sqrt{A^{2} - B^{2}}}{A}$ and l be the vertical line with equation $x = \frac{A}{e}$ . Show that for any point P on the ellipse, $\frac{F P}{D P} = e_{'}$ , where $D$ is the point on $l$ closest to $P$ .
