Solve the following trigonometric equation : sqrt2 sec theta -tan theta=1 .

sqrt(2)sec theta-tan theta=sqrt(3)

Solve the general vlaue. sqrt2 sec theta + tan theta =1

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

If tan theta + sec theta = n, then sec ^(4) theta - tan ^(4) theta- 2 sec theta tan theta =

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

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

Prove that : sqrt((1-sin theta)/(1+sin theta))= {(sec theta- tan theta, if -pi/2 < theta< pi/2), (-sec theta+ tan theta, if pi/2 < theta< (3 pi)/2):} .
