Find dy/dx if y=sin(3x)sin^3x Share with your friends Share 0 Atul Shaw answered this Dear student,Assuming the eqn. to be:y= sin(3x) sin3 xdydx= sin3 x (cos 3x)×3+sin(3x)×3sin2 x cos x=3sin2x (sin x cos 3x+sin 3x cos x)=3 sin2 x (sin(x+3x)) (sin (A+B)=sin A cos B+cos A sin B)=3sin 4x sin2 xRegards 1 View Full Answer
