    Re: Trigonomic Equations

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

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

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