The polar equation is r = 2 + cos(theta).
Given,
A choir is performing in front of an audience. a microphone is placed in front of the choir to capture sound.
The polar equation represents the microphone the choir is using i.e
On edge i.e r = 2 + cos(theta)
Hence, The polar equation is r = 2 + cos(theta).
