Hi guys, I have a question about finding a lagrangian formulation of a theory.(adsbygoogle = window.adsbygoogle || []).push({});

If I have a system for which I know the equations of motion but not the form of the lagrangian, is it possible to find the lagrangian that will give me those equations of motion? Is there a systematic way of doing this?

Thanks to anyone who can help!
