" (iii) "sqrt((1-cos theta)/(1+cos theta))=(1-cos theta)/(sin theta)=cosec theta-cot theta

(sin theta)/(1-cos theta)=cos ec theta+cot theta

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

sqrt((1+cos theta)/(1-cos theta))=csc theta+cot theta

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 |

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

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

(1)/(1-cos theta)-(1)/(1+cos theta)=(2cos theta)/(sin^(2)theta)=2cot theta xx csc

prove that (1-cos theta)/(1+cos theta)=(csc theta-cot theta)^(2)

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