I've been trying to deterimine the path of a particle. And somewhere in the solution, I need to solve this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{d^2x}{dt^2} = -\frac{L}{x}[/tex]

where L is a positive number (actually length). And ideas how this can be solved? I was just reluctant to try series expansion (frob., etc) since the problem isn't finished with the solution of this, and it'd be better if I had finite terms to go on.
