Use Cartesian coordinates to express the equations for the ellipses determined by the conditions specified in Exercises 32–37.

$foci (\pm α, 0), major axis 4 α$

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 $P$ .

In Exercises 48–55 convert the equations given in rectangular coordinates to equations in polar coordinates.

$y = x + 1$

Use Cartesian coordinates to express the equations for the ellipses determined by the conditions specified in Exercises 32–37.

$foci (0, \pm \frac{3 \sqrt{3}}{2}), minor axis 3$

Use Cartesian coordinates to express the equations for the hyperbolas determined by the conditions specified in Exercises 38–43.
