A question from coroneos that's really annoying me.

The question is

$\int \frac{dx}{3sinx+4cosx}$

The answer is
$\frac{1}{5}ln(\frac{1+2tan\frac{x}{2}}{2-tan\frac{x}{2}})$

But i keep getting
$\frac{1}{5}ln(\frac{1+2tan\frac{x}{2}}{tan\frac{x}{2}-2})$

I have no idea why, or whether or not they are the same..... can anyone help me
