हल कीजिए : ` sin 4 theta = sin theta`

sin 4 theta * sin 6 theta =

sin4 theta.sin6 theta=

( sin 2 theta + 2 sin 4 theta + sin 6 theta )/(sin 4 theta + 2 sin 6 theta + sin 8 theta ) =

Solve the following equations and write general solutions 4 sin theta sin 2 theta sin 4 theta = sin 3 theta

If : 0 lt theta lt pi/2 and sin 7theta + sin 4 theta + sin theta=0 , then : theta =

If sin 6theta = sin 4theta - sin 2theta , then theta =

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

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 4 theta + 2 sin 8 theta + sin 12 theta = ?
