sin3 theta+sin50=sin80

sin theta + sin3 theta + sin5 theta = 0

If sin theta+sin phi=sqrt(3)(cos phi-cos theta), prove that sin3 theta+sin3 phi=0

If sin theta+sin phi=sqrt(3)(cos phi-cos theta)), prove that sin3 theta+sin3 phi=0

(sin theta+2sin3 theta+sin5 theta)/(sin3 theta+2sin5 theta+sin7 theta)=(sin3 theta)/(sin5 theta)

(sin theta+2sin3 theta+sin5 theta)/(sin3 theta+2sin5 theta+sin7 theta)=(sin3 theta)/(sin5 theta)

Prove that :(sin theta+2sin3 theta+sin5 theta)/(sin3 theta+2sin5 theta+sin7 theta)=(sin3 theta)/(sin5 theta)

Prove that : (sin theta + 2 sin 3theta + sin 5theta)/(sin 3theta + 2 sin 5theta + sin 7theta) = (sin 3theta)/(sin 5theta)

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