Use Cartesian coordinates to express the equations for the parabolas determined by the conditions specified in Exercises 22–31.

$r = \frac{α}{1 + \sin θ}$

In Exercises 32–47 convert the equations given in polar coordinates to rectangular coordinates.
$θ = - \frac{π}{6}$

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

$foci (\pm 6, 0), directrices x = \pm 1$

Let $A > B > 0$ . Show that the distance from any point on the graph of the curve with equation $\frac{x^{2}}{A^{2}} + \frac{y^{2}}{B^{2}} = 1$ to the point $(- C, 0) is D_{2} = \frac{A^{2} + C x}{A^{2}}, where C = \sqrt{A^{2} - B^{2}} .$

Sketch the graphs of the equations

$r = \frac{2}{1 + 2 \cos θ}$ and $r = \frac{2}{1 + 2 \sin θ}$

What is the relationship between these graphs? What is the eccentricity of each graph?
