## Homework Statement

(1 + tg(x)) * cos^2(x) > 1, solve the inequality

## Homework Equations

tg(x) = sin(x)/cos(x)

cos(x) * sin(x) = 1/2 sin(2x)

## The Attempt at a Solution

I got my final value of:

1-sin^2(x) + 1/2 sin(2x) > 1

but because of the 2 inside the sin

I'm kinda lost so I can't use quadratic formula I presume
