csc theta(1+cos theta)(csc 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)) का मान किसके बराबर है?

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

prove that (1-cos theta)/(1+cos theta)=(csc 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 |

The value of (1+ cos theta)(1- cos theta) "cosec"^(2) theta =

( 1 + cos theta) ( 1 - cos theta ) cosec^2 theta =

Prove that (1+cosec theta -cot theta)/(1+cosec theta+cot theta)=(1-cos theta)/sin 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)) बराबर है :

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