" (27) "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

prove that , tan(2tan ^(-1) sqrt((1+cos theta )/(1- cos theta )))+tan theta =0

tan ( 2 tan ^(-1)sqrt((1+cos theta)/(1-cos theta)))+ tan theta =0

Consider the following: 1. sqrt((1-cos theta)/(1+cos theta)) = "cosec" theta -cot theta 2. sqrt((1+cos theta)/(1-cos theta))="cosec" theta +cot theta Which of the above is/are identity/ identities?

sqrt((1+ cos theta)/( 1- cos theta)) + sqrt((1- cos theta)/( 1 + cos theta )) ( 0 lt theta lt pi ) is

tan(2tan^(-1)sqrt((1+cos theta)/(1-cos theta)))+tan theta=0

Prove that :sqrt((1+cos theta)/(1-cos theta))=cos ec theta+cot theta

If sqrt((1+ cos theta )/(1- cos theta ))="cosec " theta + cot theta " then " theta lies in the quadrants

Prove the following identity : sqrt ((1+cos theta)/ (1-cos theta)) = cosec theta+cot theta

If tan theta =(4)/(3) , then the value of sqrt((1+cos theta)/(1-cos theta)) is :
