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

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

Prove the following identities: (sec-tan theta)/(sec theta+tan theta)=1-2sec theta tan theta+2tan^(2)theta

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

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

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

(cot theta)/((1-sin theta)(sec theta + tan theta)) is equal to :

(cot theta)/((1-sin theta) (sec theta + tan theta)) is equal to:

(cot theta)/((1-sin theta)(sec theta+tan theta)) is equal to: (cot theta)/((1-sin theta)(sec theta+tan theta)) का मान ज्ञात करें |

(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.
