" 35."(k-cos theta)/(1+cos theta)=(cot theta-cosec theta)^(2)

prove that (1-cos theta)/(1+cos theta)=(csc theta-cot theta)^(2)

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

cos theta . Cosec theta = cot theta

Prove that (i) (1- sin theta)/(1+ sin theta)=(sec theta - tan theta )^(2) (ii) ((1+cos theta))/((1- cos theta))= ("cosec" theta + cot theta)^(2)

(cot theta sec theta)^2-(cos theta. cosec theta)^2=1

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

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

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

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

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