s^(3)xquad " 6."sin x sin2x sin3x

int sin x sin2x sin3x

sin3x + sin x = sin2x

sin3x + sin x = sin2x

Find the least positive angle measured in degrees satisfy sin^(3)x+sin^(3)2x+sin^(3)3x-(sin x+sin2x+sin3x)^(3)

sin x+sin2x+sin3x=0 if :

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 :

Find (dy)/(dx) if,y=sin x sin2x sin3x sin4x

(cos 2x sin x + cos 6x sin 3x)/(sin 2x sin x + sin 6x sin 3x) =cot 5x
