    Trigonometric equations question

    Hi, I'm very confused with solving the following trigonometric equation:

    Solve for $\displaystyle x$ for 0 (less than or equal to) $\displaystyle x$ (less than or equal to) $\displaystyle 2 \pi$

    $\displaystyle sin x tan x + tan x - 2sinx + cos x =0$


    Im very confused, and would greatly appreciate any help.


    Thanks,

    Start by reducing this problem into terms of only $\displaystyle \sin x$ and $\displaystyle \cos x$ by using $\displaystyle \tan x = \frac{\sin x }{\cos x}$

    After this look for a common denominator i.e in this case $\displaystyle \cos x$
