`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`

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

8 sin theta * cos theta * cos 2 theta * cos 4 theta = A) sin 4 theta B) sin 8 theta C) sin 16 theta D) cos 8 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 .

sin 7 theta * sin theta+sin11theta * sin 3theta= A) sin 4 theta * sin 10theta B) cos 4 theta * cos 10 theta C) sin 8 theta * sin 4 theta D) cos 8 theta * cos 14 theta

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

If sin theta + cos theta = a " then " sin^(4) theta + cos^(4) theta =

1 + (cos 2 theta + cos 6 theta)/(cos 4 theta) = (sin 3 theta)/(sin theta).

If sin theta+cos theta=a then sin ^(4) theta+cos ^(4) theta=
