If sin^(8)theta+cos^(8)theta-1=0 then what is the value of cos^(2)theta sin^(2)theta

Prove the following identities: 2(sin^(6)theta+cos^(6)theta)-3(sin^(4)theta+cos^(4)theta)+1=0sin^(6)theta+cos^(6)theta+3sin^(2)theta cos^(2)theta=1(sin^(8)theta-cos^(8)theta)=(sin^(2)theta-cos^(2)theta)(1-2sin^(2)theta cos^(2)theta)

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

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

If s int h eta+sin^(2)theta1=1, then prove that cos^(12)theta+3cos^(8)theta+cos^(6)theta-1=0 Given that si ln theta=1-sin^(2)theta=1-sin^(2)theta=cos^(2)theta

If sintheta+sin^(2)theta=1 , then prove that cos^(12)theta+3cos^(10)theta+3cos^(8)theta+cos^(6)theta-1=0

If sintheta+sin^(2)theta=1 , then prove that cos^(12)theta+3cos^(10)theta+3cos^(8)theta+cos^(6)theta-1=0

Prove: sin^(8)theta-cos^(8)theta=(sin^(2)theta-cos^(2)theta)(1-2sin^(2)thetacos^(2)theta)

If sin theta-cos theta=0 , then the value of (sin^(8)theta+cos^(8)theta) is

If cos theta+sec theta=-2,theta in[0,2 pi] then sin^(8)theta+cos^(8)theta is equal to
