Prove that ((1+cos theta)/(1-cos theta))=("cosec"theta + "cot"theta)^(2)

Prove the following identity : sqrt ((1-cos theta)/(1+cos theta)) = cosec theta-cot theta .

Prove that sqrt((1+cos theta)/(1- cos theta)) = cosec theta + cot theta, (0^(@) lt theta lt 90^(@))

If sqrt((1+ cos theta )/(1- cos theta ))="cosec " theta + cot theta " then " theta lies in the quadrants
