Prove: `(tan theta)/(sec theta-1)=(tan theta+sec theta+1)/(tan theta+sec theta-1)`

tan2 theta(sec8 theta-1)=tan8 theta(sec4 theta-1)

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

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

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

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

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

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

Prove the following identities: (tan theta+sec theta-1)/(tan theta-sec theta+1)=(1+sin theta)/(cos theta)

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

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