tan theta+tan theta(90-theta)=sec theta+sec(90-theta)

Prove that : tantheta+tan(90^(@)-theta)=sectheta*sec(90^(@)-theta)

Prove that : tantheta+tantheta+tan(90^(@)-theta)=sectheta*sec(90^(@)-theta)

tan theta+tan(90^(@)-theta)=sec theta xx sec(90^(@)-theta)

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

Simplify sectheta[(sec theta,tan theta),(tan theta,sec theta)]-tan theta[(tan theta, sec theta),(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)] .

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

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