4 sin ((pi)/(3) + theta)sin ((pi)/(3)- theta)=

The value of sin theta sin ((pi)/(3) - theta) sin ((pi)/(3) + theta) lies in (p,q) then p= and q=

Prove that 4sin theta sin((pi)/(3)+theta)sin((2 pi)/(3)+theta)=sin3 theta

The value of sin theta sin((pi)/(3)-theta)sin((pi)/(3)+theta) lies in [pi,theta], then pi=... and theta=...

Show that 4 sin ((pi)/(3) - theta ) sin ((pi)/(3) + theta) =3-4 sin ^(2) theta

sin((pi)/(2)+theta)+sin((3 pi)/(2)+theta)+sin((5 pi)/(2)+theta)+sin((7 pi)/(2)+theta) is equal to

4sin(pi/3+theta)sin(pi/3-theta)=

Prove that: 4sin theta sin(theta+(pi)/(3))sin(theta+(2 pi)/(3))=sin3 theta

Prove that 4 sin theta sin(pi/3 + theta) sin (pi/3-theta) = sin 3 theta
