$$\int \frac{1}{\left(2 \sin{\left(x \right)} + \cos{\left(x \right)}\right) + 2}\, dx = C + \log{\left(\tan{\left(\frac{x}{2} \right)} + 1 \right)} - \log{\left(\tan{\left(\frac{x}{2} \right)} + 3 \right)}$$

-log(3 + tan(1/2)) + log(3) + log(1 + tan(1/2))
$$- \log{\left(\tan{\left(\frac{1}{2} \right)} + 3 \right)} + \log{\left(\tan{\left(\frac{1}{2} \right)} + 1 \right)} + \log{\left(3 \right)}$$

=
-log(3 + tan(1/2)) + log(3) + log(1 + tan(1/2))
$$- \log{\left(\tan{\left(\frac{1}{2} \right)} + 3 \right)} + \log{\left(\tan{\left(\frac{1}{2} \right)} + 1 \right)} + \log{\left(3 \right)}$$
-log(3 + tan(1/2)) + log(3) + log(1 + tan(1/2))
