` Sin^4theta+ Cos^4theta=?`

Prove: sin^4 theta - cos^4theta = 1 - 2cos^2 theta

Prove that: sin^4 theta - cos^4 theta= 1-2 cos^2 theta .

If A = sin^4 theta + cos^4 theta, then

If sin theta cos theta = sqrt3//4 ,then the value of sin^4theta + cos^4 theta is

If sin theta - cos theta = 0 , then what is sin^4 theta + cos^4 theta equal to ?

Prove that sin^4 theta - cos^4 theta = 1 - 2cos^2 theta

The value of Sin^4 theta+Cos^4 theta+2 Sin^2 theta Cos^2 theta is: Sin^4 theta+Cos^4 theta+2 Sin^2 theta Cos^2 theta का मान है:

The maximum value of sin ^4 theta + cos ^4 theta is

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:
