D) $r = 4 \cos \theta$

Question

Quizplus · Accepted Answer

The equation $y = 4$ in Cartesian coordinates can be converted to polar coordinates using the relationship $y = r\sin\theta$. Substituting $y = 4$ gives $4 = r\sin\theta$, which can be rearranged to $r = \frac{4}{\sin\theta} = 4\csc\theta$.
