If `sin theta+ sin^(2)theta=1`, then prove that `cos^(2) theta+cos^(4) theta=1.`

If sin theta+sin^(2)theta=1, prove that cos^(2)theta+cos^(4)theta=1

If sin theta+ sin^2 theta = 1 , prove that cos^2 theta+ cos^4 theta = 1 .

If sin theta+sin^(2)theta=1 Prove that cos^(2)theta+cos^(4)theta=1

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

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

Given that sin theta+2cos theta=1 then prove that 2sin theta-cos theta=2

If x=(2sin theta)/(1+cos theta+sin theta), then prove that (1-cos theta+sin theta)/(1+sin theta) is equal to x

Prove that : sin^(4)theta + cos^(4)theta = 1 - 2 cos^(2) theta + 2 cos^(4)theta
