हल कीजिए - `sin 9 theta = sin theta`

Solve : sin 9 theta = sin theta.

(sin 3 theta + sin 5 theta + sin 7 theta + sin 9theta)/(cos 3 theta + cos 5 theta + cos 7 theta + cos 9 theta )=

(sin 3 theta + sin 5 theta + sin 7 theta + sin 9theta)/(cos 3 theta + cos 5 theta + cos 7 theta + cos 9 theta )=

( sin 3 theta + sin 5 theta + sin 7 theta + sin 9 theta)/( cos 3 theta + cos 5 theta + cos 7 theta + cos 9 theta) is equal to

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

Solve the equation sin 9 theta=sin theta

Solve the equation sin9 theta=sin theta

If" " 0 < theta < pi/2, " then show that " sin theta sin 2 theta sin 3 theta le 9/16

If sin theta =4/5 , find the vlaue of sin3 theta . यदि sin theta =4/5 , sin3 theta का मान प्राप्त कीजिए
