If `f(x)=e^(x-[x]+|cos pi x|+|cos2 pi x|+...+|cos npi x|)` then the period of `f(x)` is

If f(x)=e^(x-[x]+|cos pi x|+|cos2 pi x|+...+|cos n pi x|) then the period of f(x) is

The period of f(x)=e^(x)-[x||cos(pi x ) | + |cos(2 pi x)| + ........|cos( n pi x)|) (where [.] is G.I.F) is

The period of the function f(x)=e^(x-[x]+|cos pi x|+|cos2 pi x|+...|cos n pi x|) is

If f(x) = cos x cos 2x cos 4x cos 8x cos 16x then find f' (pi/4)

If f(x) = cos x cos 2x cos 4x cos 8x cos 16x then find f' (pi/4)

If f(x) = cos x cos 2x cos 4x cos (8x). cos 16x then find f' (pi/4)

If f(x) = cos x cos 2x cos 4x cos (8x). cos 16x then find f' (pi/4)
