Show :
`Sin^4theta + Cos^4theta = 1 - 1/2 Sin^2(2theta)`

Show : Sin^4theta - Cos^4theta = Sin^2theta - Cos^2theta

Show : 1 - Sin^4theta = Cos^2theta ( 1 + Sin^2theta )

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

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

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

The value of (1-2 sin^2 theta cos^2 theta )/(sin^4 theta +cos^4 theta )-1 is: (1-2 sin^2 theta cos^2 theta )/(sin^4 theta +cos^4 theta )-1 का मान है :

If cos^4 theta - sin^4 theta = 2/3 ,then the value of 1 - 2 sin^2 theta is

Find the value of (sin^4theta+cos^4theta)/(1-2sin^2 thetacos ^2 theta)

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

If 3 cot theta= 2 , show that ((4 sin theta - 3 cos theta ))/((2 sin theta + 6 cos theta))=(1)/(3)
