Simplify :
`( Sin^4theta - Cos^4theta ) /( Sin^2theta - Cos^2theta )`

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

"(i) "sin^(4)theta-cos^(4)theta=sin^(2)theta-cos^(2)theta

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

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

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

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 :

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

Solve cos^(4)theta-sin^(4)theta=cos^2theta
