## Question

### Solution

Correct option is

4

As we know the graph of both (x) = 2cos x and g(x) = |sin x|

∴ Their point of intersection are number of solutions

Thus from the above graph the two functions intersect at two points between [0, 2π] and we know cos x is periodic with period 2π, so it has same number of solutions for the interval [2π, 4π]

∴ Total number of solutions of
