If `f(sin x) = sin 3x`, then `f(cos 30^@)` is equal to

If f(sin x)=sin3x, then f(cos30^(@)) is equal to

If f(x) = e^(x) sin x , then f^((6)) (x) is equal to

If f(x)= |cos x- sin x| , then f'((pi)/(3)) is equal to …….

If f(x) = (cos^2 x + sin^4 x)/(cos^4x + sin^2 x) , then f(2016) is equal to

If f(x)=sin(cosx) , then f'(x) is equal to

If f(x)=|cos x-sin x|, then f'((pi)/(2)) is equal to

If f(x)=(cos^2x+sin^4x)/(sin^2 x+cos^4x), for x in R, then f(2002) is equal to

If f(x)=(cos^(2)x+sin^(4)x)/(sin^(2)x+cos^(4)), for x in R, then f(2002) is equal to
