Talk:Action-angle coordinates

Proper definition of the action-angle variables edit

I believe that the author of the article confused the notation when talking about the action-angle variables. In particular, the variable   is generally called the angle and   is the action. I would like to correct this if there are no objections. Also, one should probably indicate that the derivation holds only for separable   in proper separated coordinates  .

In accordance with Goldstein's nomenclature, I think you are using the right vocabularies. Please make the necessary correction. Thanks!LaoChen (talk) 05:27, 17 October 2010 (UTC)Reply
