Simplify `y=sin^3 theta + cos^3 theta`.

Simplify sin^8theta-cos^8theta

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

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

The value of (sin^3 theta + cos^3 theta)/(sin theta+ costheta)+((cos^3 theta - sin^3 theta))/(cos theta - sin theta) is

Simplify (sin theta+cos theta+1)/(sin theta+cos theta-1)-(1+sin theta-cos theta)/(1-sin theta+cos theta)

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

Simplify: cos^(3)theta+sin^(3)theta=

(sin theta+cos theta)(1-sin theta cos theta)=sin^3 theta+cos^3 theta

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