As part of solving a DE I need to make this friendlier to integrate:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{2u}{1+u^{-2}}[/tex]

I figured trying to divide it couldnt hurt. I got:

[tex]u^{-1}+u^{-3}[/tex]

I can't type out all the steps easily, I'm on a mobile device at the moment. That answer looks suspect, did I do it correctly?
