(10^(3))/(20)(1-cos theta)/(1+cos theta)=(cot theta-csc theta)^(2)

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

cos theta . Cosec theta = cot theta

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

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

(cot theta sec theta)^2-(cos theta. cosec theta)^2=1

Prove that (i) (1- sin theta)/(1+ sin theta)=(sec theta - tan theta )^(2) (ii) ((1+cos theta))/((1- cos theta))= ("cosec" theta + cot theta)^(2)

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

Prove that ((1+cos theta)/(cos theta))((1-cos theta)/(cos theta))cosec^(2)theta=sec^(2)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)) का मान किसके बराबर है?

Prove that ((1+cos theta)/(1-cos theta))=("cosec"theta + "cot"theta)^(2)
