`sqrt((1+cos theta)/(1-cos theta))=`

Prove each of the following identities : (i) sqrt((1+ sin theta)/(1- sin theta)) = ( sec theta + tan theta) (ii) sqrt((1- cos theta)/(1+ cos theta))= ("cosec" theta - cot theta) (iii) sqrt((1+ cos theta)/(1- cos theta))+ sqrt((1- cos theta)/(1+ cos theta)) = 2 "cosec" theta

If y=sqrt((1+cos2 theta)/(1-cos2 theta)) then (dy)/("d"theta) at theta = (3pi)/4 is

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 |
