The period of `cos5 theta` is

The period of cos( theta/2) is

The period of cos(theta/2)

The period of cos(theta/2)

Period of sin theta - sqrt2 cos theta is

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

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?

If 3 sin theta + 5 cos theta =5, then the value of (5 sin theta - 3 cos theta ) is

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