What is the value of [(cos 3 theta + 2cos 5 theta+ cos 7 theta)/(cos theta + 2cos 3 theta + cos 5 theta)] + sin 2 theta tan 3 theta ? [(cos 3 theta + 2cos 5 theta+ cos 7 theta)/(cos theta + 2cos 3 theta + cos 5 theta)] + sin 2 theta tan 3 theta का मान क्या है?

Find the value of (cos6 theta+6cos4 theta+15cos2 theta+10)/(cos5 theta+5cos theta+10cos theta)

The value of (cos6theta+6cos4theta+15cos2theta+10)/(cos5theta+5cos3theta+10costheta) is :

If 3cos theta+4cos theta=5 then 4sin theta-3cos theta is equal to

If sin7theta=cos5 theta , then general value of theta is:
