Prove the following identities : sqrt ((1 - cos A) /(1 + cos A)) = cosec A - cot A

sqrt((1-cos A)/(1+cos A))+sqrt((1+cos A)/(1-cos A))=2cosec A

Prove that : (1 + cos A)/(1 - cos A) = (cosec A + cot A)^(2)

Prove the trigonometric identities: sqrt((1-cos theta)/(1+cos theta))=csc theta-cot theta

sqrt((1+cos theta)/(1-cos theta))=csc theta+cot theta

sqrt((1-cos theta)/(1+cos theta))=cosec theta-cot theta (Prove It)

Prove the following identities : cosec A (1 + cos A) (cosec A - cot A) = 1

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