`(tan theta)/( sec theta - 1) - (tan theta)/( sec theta + 1) = 2 cot theta`

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

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

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

Prove that (tan theta)/(sec theta-1)+(tan theta)/(sec theta+1)=2 "cosec"theta.

Prove each of the following identities : (i) (tan theta)/((sec theta -1)) + (tan theta)/((sec theta +1)) = 2 "cosec" theta (ii) (cot theta)/(("cosec" theta +1))+ (("cosec" theta +1))/(cot theta ) = 2 sec theta

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

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

( sec theta + tan theta -1)/( tan theta - sec theta +1)

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

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