Prove that : cos^3 2theta+3cos2theta=4(cos^6theta-sin^6 theta)

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

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

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

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

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

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

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

What is the value of [(cos^3 2 theta+ 3 cos 2 theta)div (cos^6 theta- sin^6 theta)] ? [(cos^3 2 theta+ 3 cos 2 theta)div (cos^6 theta- sin^6 theta)] का मान क्या है?
