Q_(2)*cosec theta(1+cos theta)(cosec theta-cot theta)=1

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

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

prove that (cosec theta + cot theta)/(cosec theta- cot theta) = (cosec theta +cot theta)^2

If sqrt((1-cos theta)/(1+cos theta)) xx sqrt((cosec theta-cot theta)/(cosec theta+cot theta))= (1-r)/(1+r) , then the value of r is: यदि sqrt((1-cos theta)/(1+cos theta)) xx sqrt((cosec theta-cot theta)/(cosec theta+cot theta))= (1-r)/(1+r) है, तो r का मान ज्ञात करें |

(1+cosec theta - cot theta)/(1+cosec theta + cot theta)=

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