If `32sin^6theta=10-15cos2theta+bcos4theta+acos6theta`, show that `tan theta tan 5 theta =(a+b-5)/(a-b+7)`.

If 32sin^(6)theta=10-15cos2 theta+b cos4 theta+a cos6 theta ,show that tan theta tan5 theta=(a+b-5)/(a-b+7)

If " "32 sin^(6) theta = 10 - 15 cos 2 theta + b cos 4 theta + alpha cos 6 theta,"show that, " tan theta tan 5 theta = (a+b-5)/(a-b+7).

If cos theta=0.6 , then show that (5 sin theta-3 tan theta)=0 .

(cos6 theta-cos4 theta)/(sin6 theta+sin4 theta)=-tan theta

(sin5 theta-2sin3 theta + sin theta) / (cos5 theta-cos theta) = tan theta

Show that, 32 sin^(6) theta = 10 - 15 cos 2 theta + 6 cos 4 theta - cos 6 theta

If a cos phi=b cos theta, show that a tan theta+b tan phi=(a+b)tan((theta+phi)/(2))

Prove that (sin theta + sin 3theta+ sin 5 theta + sin 7theta)/(cos theta + cos 3theta + cos 5 theta + cos 7theta) = (tan 3theta + tan theta)/(1 - tan 3theta tan theta) .

6sin theta+7cos theta=9 if tan theta=

For any angle theta . (sin2theta+sin4theta+sin6theta+sin8theta)/(cos2theta+cos4theta+cos6theta+cos8theta)=.... (a) tantheta (b) tan 3theta (c) tan5theta (d) none of these
