I am trying to do the integration(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int_{0}^\infty \frac{x}{(x^2+c^2)^3} dx [/tex]

At first I tried doing it with contour integration, but yielded zero. Later I figured out that it can actually be done simply by making a change in variable (squeezing the x in the numerator into the dx). Is it possible to do it with contour integration (though not necessary)?
