9. Polar Equations

Graph each polar equation. Also, identify the type of polar graph.

r² = 4 cos 2θ

Identify whether the given equation is that of a cardioid, limaçon, rose, or lemniscate.

$r=3+2\(\cos\]\theta\)$

Match each equation with its polar graph from choices A–D.

r = 2/(cosθ + sinθ)

Graph $r^2=9\(\sin\)2\(\theta\)$

In Exercises 35–44, test for symmetry and then graph each polar equation. r = 2 + 3 sin 2θ
