A) \[\frac{\pi }{2}\]
B) \[\frac{\pi }{3}\]
C) \[\frac{\pi }{4}\]
D) None of these
Correct Answer: C
Solution :
Here \[r=\sin \theta +\cos \theta \] and \[r=2\sin \theta \] \[\therefore \] \[2\sin \theta =\sin \theta +\cos \theta \Rightarrow \sin \theta =\cos \theta \] \[\Rightarrow \] \[\tan \theta =1\Rightarrow \theta =\frac{\pi }{4}\].You need to login to perform this action.
