[" 3.What "(cat theta)/((1-tan theta))=(1+sec theta cos c cos)],[(1-cos theta)]

(cos theta)/(sec theta-tan theta)=1+sin theta

(sin theta tan theta)/(1-cos theta)=1+sec theta

(tan theta)/(1-cot theta)+(cot theta)/(1-tan theta)=1+sec theta*cos ec theta

Prove that (sec theta+tan theta-1)/(tan theta-sec theta+1)=(cos theta)/(1-sin theta)

Prove that (sec theta+tan theta -1)/(tan theta -sec theta +1)=cos theta/(1-sin theta)

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

Prove that: (sec theta + tan theta -1)/(tan theta - sec theta +1) = (cos theta)/(1- sin theta)

Prove that :(sec theta+tan theta-1)/(tan theta-sec theta+1)=(cos theta)/(1-sin theta)

(tan theta)/(sec theta-1)+(tan theta)/(sec theta+1)=2cos ec| 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)) बराबर है :
