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

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

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

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

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

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

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

If (sec theta+tan theta)/(sec theta-tan theta)=5 , and theta is an acute angle, then the value of (3 cos^2 theta+1) /(3 cos^2 theta-1) is: यदि (sec theta+tan theta)/(sec theta-tan theta)=5 , तो (3 cos^2 theta+1) /(3 cos^2 theta-1) का मान ज्ञात करें जहाँ theta एक न्यून कोण है

The value of log[(sec theta+tan theta)(sec theta-tan theta)] is ________
