find  ∫∫_D ((arctan((√(x^2 +y^2 ))))/(x+y))dxdy  D={(x,y) / 0≤x≤1 and 1≤y≤2}
$${find}\:\:\int\int_{{D}} \frac{{arctan}\left(\sqrt{{x}^{\mathrm{2}} +{y}^{\mathrm{2}} }\right)}{{x}+{y}}{dxdy} \\ $$$${D}=\left\{\left({x},{y}\right)\:/\:\mathrm{0}\leqslant{x}\leqslant\mathrm{1}\:{and}\:\mathrm{1}\leqslant{y}\leqslant\mathrm{2}\right\} \\ $$
