A) \[\pi \]
B) \[2\pi \]
C) \[\frac{\pi }{2}\]
D) None of these
Correct Answer: B
Solution :
\[2\sin x\] is a periodic function of period \[2\pi \] and\[3\cos 2x\]is a periodic function of\[\pi \]. \[\therefore \] \[f(x)=2\sin x+3\cos 2x\] has period LCM of\[\{\pi ,\,\,2\pi \}=2\pi \]You need to login to perform this action.
