Can someone tell me how to show that the value of(adsbygoogle = window.adsbygoogle || []).push({});

x/[Sqrt(x^2+r^2)*r^2]

approaches 1/r^2 when x approaches infinity? Cant figure out how to show this analytically, but by plotting the function it is obvious.

Btw, how do I get latex graphics to work?? It doesn't really work when I preview the post.

Thanks!
