A) \[\pi /2\]
B) \[\pi /8\]
C) \[\pi /4\]
D) None of these
Correct Answer: B
Solution :
Since, \[|\sin x|+|\cos x|\]is a periodic function with period\[\pi /2\]. \[\therefore \]\[f(x)=|\sin 4x|+|\cos 4x|\]is a periodic function with period\[\frac{1}{4}.\frac{\pi }{2}ie,\,\,\frac{\pi }{8}\].You need to login to perform this action.
