can someone please explain how to do this problem ;(

Answer 2

This is an odd question, I keep getting 0. But your answer is probably 2.

tan(2x) is a double angle and can be simplified to : 2tan(x)

I tried solving for when it equals 0 and my answer is still the same. Very odd. I would select 2.

Edit: Original poster confirmed it was 2
