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

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

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

Prove that : sin theta cos^3 theta - cos theta sin^3 theta = 1/4 sin4theta .

4 sin theta * cos^(3) theta-4 cos theta * sin ^(3)theta= A) 4 cos theta B) cos 4 theta C) 4 sin theta D) sin 4 theta

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

sin4 theta-sin2 theta=cos3 theta

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

(sin3 theta+cos3 theta)/(cos theta-sin theta)=1+2xx sin2 theta

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