40." Prove it ":(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=2cosec theta

Prove that : (sin theta)/(1+cos theta) + (1+cos theta)/(sin theta)= 2 cosec theta .

Prove each of the following identities : (sin theta)/((1+ cos theta)) + ((1+ cos theta))/(sin theta) = 2 "cosec" theta

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

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

prove that (cos theta)/(1-sin theta)+(cos theta)/(1+sin theta)=(2)/(cos theta)

(sin^(2) theta)/(1-cos theta)-(cos^(2) theta)/(1-sin theta)=cos theta-sin theta

Prove that cos^2 theta cosec theta+sin theta=cosec theta

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