9. Polar Equations

Convert each equation to its rectangular form.

$r=\(\frac{2}{1-\sin\theta}\)$

In Exercises 49–58, convert each rectangular equation to a polar equation that expresses r in terms of θ.

y² = 6x

In Exercises 54–60, convert each polar equation to a rectangular equation. Then use your knowledge of the rectangular equation to graph the polar equation in a polar coordinate system. r = 5 csc θ
