(cos x)/(cosec theta-1)+(cos theta)/(cosec theta+1)=2tan theta

(cos theta)/(cosec theta+1)+(cos theta)/(cosec theta-1)=2tan theta

(iii) (cos theta)/(csc theta+1)+(cos theta)/(csc theta-1)=2/cottheta

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

((sec theta + tan theta) (1- sin theta))/(cosec theta (1 + cos theta)(cosec theta - cot theta)) is equal to: ((sec theta + tan theta) (1- sin theta))/(cosec theta (1 + cos theta)(cosec theta - cot theta)) बराबर है :

(1/(cos theta)-1/(sin theta))+1/(cosec theta-cot theta)-1/(sec theta+tan theta) =?

((sec theta+tan theta)(1-sin theta))/ (cosec theta(1+cos theta)(cosec theta-cot theta)) is equal to: ((sec theta+tan theta)(1-sin theta))/ (cosec theta(1+cos theta)(cosec theta-cot theta)) का मान किसके बराबर है?

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

(tan theta)/(sec theta+1)+(cot theta)/(csc theta+1)=csc theta+sec theta-csc theta sec theta

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

Prove each of the following identities : (i) (1+ cos theta)(1- cos theta)(1+ cot^(2) theta)=1 (ii) "cosec" theta (1+ cos theta)("cosec" theta - cot theta)=1
