" (ii) "(sin theta-cos theta+1)/(sin theta+cos theta-1)=(1+sin theta)/(cos theta)

Prove the following identities: (sin theta-cos theta+1)/(sin theta+cos theta-1)=(1+sin theta)/(cos theta)

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

(sin theta-cos theta + 1) / (sin theta + cos theta-1) = sec theta + tan theta

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

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

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

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

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

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

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