# Thread: Solving a trig equation

1. ## Solving a trig equation

cos 2x tan x ( tan x - 1 ) + 2 = 0,x from 0 to 2pi

2. Is there any more work you can show us?

As a method I would use a double angle formula with cos2x

EDIT: Now that this has been moved, I'm wondering what the question is. I assumed it was an integration problem but that's not very clear.
