The function `f(x)=x-[x]` is a periodic with period.

The function f(x)=|cos| is periodic with period

The function f(x)=|cos| is periodic with period

If f(x) is a periodic function with period T, then

The function f(x)=|sin4x|+|cos2x| is a periodic function with period

Statement 1: The function f(x)=x^(2)+tan^(-1)x is a non-periodic function.Statement x .The sum of two non- periodic functions is always non-periodic.

If f(x + 2a) =f(x - 2a), then f(x) is a)a periodic function with period 4a b)a periodic function with period 2a c)a periodic function with indeterminate period d)a non periodic function

If f(x) is periodic function with period, T, then
