" (iii) "64cos^(3)theta sin^(4)theta=cos7 theta-cos5 theta-3cos3 theta+3cos theta

Prove that, 64cos^(3) theta sin^(4) theta = cos 7 theta - cos 5 theta - 3 cos 3theta+3 cos theta

3. sin^(3)theta+cos^(3)theta=(sin theta+cos theta)(1-sin theta cos theta)

2cos theta-cos3 theta-cos5 theta-16cos^(3)theta sin^(2)theta=

2cos theta-cos3 theta-cos5 theta-16cos^(3)theta sin^(2)theta=

If cos theta+cos7 theta+cos3 theta+cos5 theta=0, then theta=

2 cos theta - cos 3 theta - cos 5 theta - 16 cos^(3) theta sin^(2) theta =

Prove that: (sin^(3) theta + cos^(3) theta)/(sin theta + cos theta) = 1-sin theta cos 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?

Prove that (cos^3 theta-sin^3 theta)/(cos theta-sin theta) = 1+cos theta sin theta

(cos3 theta+2cos5 theta+cos7 theta)/(cos theta+2cos3 theta+cos5 theta)=cos2 theta-sin2 theta tan3 theta
