" frove that "(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)-2cosec theta

(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=2cos ec theta

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

(sin theta)/(cosec theta)+(cos theta)/(sec theta)=1

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

" 4."(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=(2)/(sin theta)

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

Prove that : (1-sin theta cos theta)/ (cos theta (sec theta - cosec theta)) times (sin^2 theta - cos^2 theta)/(sin^3 theta + cos^3 theta) = sin theta

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