" 14.Prove that "(1-cos theta)/(sin theta)=(sin theta)/(1+cos theta)

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

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

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

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

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

Prove that (1+cos theta)/(sin theta)=(1+sin theta+cos theta)/(1+sin theta-cos theta) .

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

Prove that: ((1)/(cos theta)-(1)/(sin theta))(1+(sin theta)/(cos theta)+(cos theta)/(sin theta))=sec theta tan theta-cosec theta cot theta

Prove that : (cos theta)/(1-tan theta)+(sin theta)/(1-cot theta)=sin theta+cos theta

Prove that : (cos theta)/(1-tan theta) + (sin theta)/(1-cot theta) = sin theta + cos theta
