सिद्ध करें कि
`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

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

Prove that : (sin theta)/(1+cos theta) + (1+cos theta)/(sin theta)= 2 cosec theta .

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

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

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

If pi lt theta lt 2pi then sqrt ((1+cos theta)/(1-cos theta))= a. cosec theta+cot theta , b. cosec theta - cot theta , c. cot theta-cosec theta , d. -cosectheta - cot theta
