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

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).

cos^(3)2 theta+3cos2 theta=4(cos^(6)theta-sin^(6)theta)

Prove that cos^6 theta+ sin^6 theta= 1-3sin^2 theta cos^2 theta

sin ^(6) theta+cos ^(6) theta+3 sin ^(2) theta . cos ^(2) theta=

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 sin theta+sin ^(2) theta+sin ^(3) theta=1 then cos ^(6) theta-4 cos ^(4) theta+8 cos ^(2) theta=

sin^(6)theta+cos^(6)theta+3sin^(2)theta cos^(2)theta=1

If sin theta + sin^(2) theta =1 then cos^(4) theta + cos^(8) theta + 2 cos^(6) theta =
