If `f'(x)=sinx+sin4xcosx` then `f^(prime)(2x^2+pi/2)=`

If f'(x)=sin x+sin4x cos x then f'(2x^(2)+(pi)/(2))=

If f'(x)=sinx+sin4x.cosx, then f'(2x^(2)+pi/2) is

If f'(x)=sinx+sin4x.cosx, then f'(2x^(2)) is

If f'(x)=sinx+sin4x.cosx, then f'(2x^(2)) is

If f'(x)=sinx+sin4x.cosx, then f'(2x^(2)) is

Let f(x) be a differentiable function such that f'(x)=sinx+sin4xcosx. Then f'(2x^(2)+(pi)/(2))"at "x=sqrt((pi)/(2)) is equal to

Let f(x) be a differentiable function such that f'(x)=sinx+sin4xcosx. Then f'(2x^(2)+(pi)/(2))"at "x=sqrt((pi)/(2)) is equal to

If f(x)=|x|^(|sinx|), then find f^(prime)(-pi/4)
