The Answer of Suppose   $ r_{1}=12\left(\cos \frac{7 \pi}{11}+i \sin \frac{7 \pi}{11}\right) $ and  $ r_{2}=3\left(\cos \frac{\pi}{11}+i \sin \frac{\pi}{11}\right) $ . Find the polar form of  $ \frac{r_{1}}{r_{2}} $   . Give the exact answer using radians for $ \theta $  .

Suppose r1=12(cos⁡7π11+isin⁡7π11) r_{1}=12\left(\cos \frac{7 \pi}{11}+i \sin \frac{7 \pi}{11}\right) r1​=12(cos117π​+isin117π​) And r2=3(cos⁡π11+isin⁡π11) r_{2}=3\left(\cos \frac{\pi}{11}+i \sin \frac{\pi}{11}\right) r2​=3(cos11π​+isin11π​)

Suppose $r_{1}=12\left(\cos \frac{7 \pi}{11}+i \sin \frac{7 \pi}{11}\right)$ And $r_{2}=3\left(\cos \frac{\pi}{11}+i \sin \frac{\pi}{11}\right)$
