` r = a sec (theta - alpha)`

Eliminate theta between the equation a sec theta + b tan theta + c=0 and p sec theta + q tan theta + r=0

If sec theta + tan theta = 12.5 , then sec theta - tan theta = ?

If sec theta + tan theta = 4 , then sec theta- tan theta =?

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

If sec(theta-alpha), sectheta and sec(theta+alpha) are in AP, where cos alpha ne 1 then what is the value of sin^2 theta + cos alpha ?

If alpha and beta are the solutions of the equation a tan theta+b sec theta=c then (alpha+beta)=

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
