` {(1- tan theta) ( 1+tan theta)} / (cosec ^2 theta)`

Prove each of the following identities : ((1+ tan^(2) theta) cot theta)/("cosec"^(2) theta ) = tan theta

tan theta+(1)/(tan theta)=sec theta cosec theta

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

Prove that: (1 + cot theta - "cosec" theta) (1+ tan theta + sec theta)=2

((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 :

Prove each of the following identities : (tan theta)/((1-cot theta)) + (cot theta)/((1- tan theta)) = (1+ sec theta "cosec" theta)

Prove that : (tan theta)/(sec theta -1) + (tan theta)/(sec theta + 1) = 2 cosec 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?
