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

Simplify sqrt(1- sin^2theta ) + (1 cos^2theta)

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

Simplify cos^2theta-sin^2theta

Simplify sin^8theta-cos^8theta

Simplify (sin(180^(@)+theta)cos(360^(@)-theta)tan(270^(@)-theta))/(sec^(2)(90^(@)+theta)tan(-theta)sin(270^(@)+theta))

Simplify: (sin8 theta cos theta-sin6 theta cos3 theta)/(cos2 theta cos theta-sin3 theta sin4 theta)

Simplify cos^8theta-sin^8theta

Simplify [(sin theta)/(cos theta)+(cos theta)/(sin theta)]^(2)

[[ Simplify :cos thetacos theta,sin theta-sin theta,cos theta]]+sin theta[[sin theta,-cos thetacos theta,sin theta]]
