हल कीजिए : ` sin m theta +sin n theta =0`

5. sin m theta=sin n theta

cos m theta-sin n theta=0

Solve the following trigonometric equation : sin m theta + sin n theta = 0 .

Solve that equation : sin m theta+sin n theta=0

sin theta + sin3 theta + sin5 theta = 0

If sin 6 theta + sin 4theta + sin 2theta= 0 , then general value of theta is (n is integer)

Prove by Principle of Mathematical Induction, that : sin theta + sin 2 theta + sin 3 theta + ........ + sin n theta= (sin (n+1)theta/2 sin frac (n theta)(2))/(sin frac (theta)(2)) for all n in N.

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

If sin 7theta + sin 4theta + sin theta = 0, 0 le theta le pi//2 , then theta =
