I have this eq.:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]y'=\frac{1}{(1+x^2+y^2)}[/tex]

I'm able to show that it has a unique solution for [tex]-\infty<x<\infty[/tex], and that the solution is an odd funktion.

What can I say about the limit of the solution as x grows towards infinity?
