" Show that "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

sin4 theta-sin2 theta=cos3 theta

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 .

(3sin theta-sin3 theta)/(3cos theta+cos3 theta)=

Show that ((cos theta - cos 3 theta) (sin 8 theta + sin 2 theta))/((sin 5 theta - sin theta) (cos 4 theta- cos 6 theta))=1

Solve sqrt(3)cos theta-3sin theta=4sin2 theta cos3 theta

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

( cos 3 theta - sin 3 theta )/( cos theta+ sin theta ) =
