`"2(sin^(4)theta+cos^(4)theta)=1`

2(sin^(2)theta+cos^(2)theta)-3(sin^(4)theta+cos^(4)theta)+1 is equal to a.0 b.1 c.2 d.none of these

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

The value for 2(sin^(6)theta+cos^(6)theta)-3(sin^(4)theta+cos^(4)theta)+1 is

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)

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

If sin^(2)theta-cos^(2)theta=(1)/(4) , then the value of (sin^(4)theta-cos^(4)theta) is :

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

If sin^(4) theta+cos^(4)theta=(1)/(2) , then find sin theta cos theta .
