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

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

(sec theta+ tan theta)(sec theta-tan theta) =____.

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

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

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

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

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

Simplify: tan theta[(sec theta, tan theta),(tan theta, -sec theta)] + sec theta[(- tan theta, -sec theta),(-sec theta, tan theta)] .

a sec theta+b tan theta=1,a sec theta-b tan theta=5 then a^(2)(b^(2)+4)
