" 17."cos x cos2x cos4x cos8x=(sin16x)/(16sin x)

cos x cos 2x cos 4x cos 8x =(sin 16x)/(16sin x)

prove that cos x cos2x cos4x cos8x=(sin16x)/(16sin x)

8cos x cos2x cos4x = (sin6x) / (sin x)

16 sin x cosx cos 2x cos 4x cos 8x in

The value of int_( sin )x cos x cos2x cos4x cos8x cos16x)dx is int(sin x cos x cos2x cos4x cos8x cos16x)dx is equal to

The equation 8cos x*cos2x*cos4x=(sin6x)/(sin x) has a solution if

If f(x)=cos x cos2x cos4x cos8x cos16x then

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 cos2x cos4x cos8x cos16x then f'((pi)/(4)) equals
