सिद्ध कीजिए : `(sin theta ) /(sec theta + tan theta - 1) + (cos theta)/(" cosec " theta + cot theta - 1) = 1`

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

(cosec theta -sin theta ) (sec theta - cos theta ) (tan theta + cot theta ) = 1.

( 1 + tan theta + sec theta ) ( 1 + cot theta - cosec theta ) =

sin 2 theta * (tan theta + cot theta)= A) sec theta B) csc theta C)1D)2

( sec theta + tan theta )/("cosec " theta + cot theta ) -(sec theta - tan theta )/( " cosec" theta - cot theta )=

("cosec " theta - sin theta ) ( sec theta - cos theta ) ( tan theta + cot theta ) =

If tan theta=1 , then (sin theta+cos theta)/(sec theta+cosec theta)=

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

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)
