" If "f(x)=sin x sin2x sin3x," find "f''(x)

If f(x) = |(sin x + sin 2x + sin 3x, sin 2x , sin 3x),(3 + 4 sin x, 3, 4 sin x),(1 + sin x, sin x, 1)| then the value of int_0^(-pi//2) f(x) dx equals :

f(x)=(1)/(sin x cos x) find ,f'(x)=?

f(x)=sin sin sin x is a function

If f(x)=|(sin x+sin x 2x+sin3x,sin2x,sin3x),(3+4sinx,3,4sinx),(1+sinx,sinx,1)|, then the value of int_0^(pi/2) f(x) dx is

If f(x)=cos x+sin x, find f((pi)/(2))

If f(x)=|(sin x+sin 2x+sin3x,sin2x,sin3x),(3+4sinx,3,4sinx),(1+sinx,sinx,1)|, then the value of int_0^(pi/2) f(x) dx is

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

If f(x)=xe^(x) sin x then find f'(x) .
