A) $r ^ { 2 } = 9 \sec \theta \csc \theta$
B) $r ^ { 2 } = 3 \sec \theta \csc \theta$
C) $r ^ { 2 } = 3 \sin \theta \cos \theta$
D) $r ^ { 2 } = 9 \sin \theta \cos \theta$
E) $\theta = 9 \sin \theta \cos \theta$

Quizplus · Accepted Answer

To convert the rectangular equation $25xy = 225$ to polar form, use the relationships $x = r\cos\theta$ and $y = r\sin\theta$. Substituting these into the given equation yields $25(r\cos\theta)(r\sin\theta) = 225$, which simplifies to $r^2\cos\theta\sin\theta = 9$. This can be rewritten using trigonometric identities as $r^2 = 9\sec\theta\csc\theta$, matching choice A.
