1. ## Re: Trigonomic Equations

Ah, well the question only asked for the solutions in between zero and two pi.

2. ## Re: Trigonomic Equations

All the general solutions are given, the only thing you have to do is determining the solutions in $\displaystyle 0<x<2\pi$.

For example one of the solutions was:
$\displaystyle x=\frac{-\pi}{6}+2k\pi$
And so the ony solution for $\displaystyle x\in ]0,2\pi[$ is:
$\displaystyle x=\frac{11\pi}{6}$

I believe $\displaystyle \frac{7\pi}{6}$ is a valid answer too, it fufilled the equation when I plugged it back in to check.
