3x cos^(3)theta sin3 theta+sin^(3)theta cos3 theta=(3)/(4)sin4 theta

cos^(3)theta sin 3theta + sin^(3)theta cos3theta=3/4

Prove that cos^(3)thetasin3theta+sin^(3)theta cos 3theta=(3)/(4)sin 4 theta .

Prove that cos^(3)thetasin3theta+sin^(3)theta cos 3theta=(3)/(4)sin 4 theta .

Prove that cos^(3)thetasin3theta+sin^(3)theta cos 3theta=(3)/(4)sin 4 theta .

sin4 theta-sin2 theta=cos3 theta

sin theta cos ^ (3) theta-cos theta sin ^ (3) theta = (1) / (4) sin4 theta

prove : cos^3 thetasin3theta+sin^3thetacos3theta=3/4 sin4theta

Prove that sin theta cos^(3)theta - cos theta sin^(3) theta = (1)/(4) sin 4 theta .

The normal to the curve x= 3 cos theta - cos^(3) theta , y=3 sin theta - sin^(3) theta at theta = (pi)/(4) -

Solve sin^(3)theta cos theta-cos^(3)theta sin theta=(1)/(4)
