Question

tan ^2x+sec^2x=3 solve this problem

Answer 1

Given, tan^2 x + sec^2 x = 3 can be written as

            tan^2 x + 1+ tan^2 x = 3

           2 tan^2 x = 3 - 1

           2 tan^2 x = 2

             tan^2 x = 2/2

                          = 1

                tan x = -1,1

                      x = pi/4, 3pi/4,5pi/4,7pi/4.


Hope this helps!

Answer 2

Tan^2x+1=sec^2x
So tan^2x =1
X=45°
