Proper definition of the action-angle variables

I believe that the author of the article confused the notation when talking about the action-angle variables. In particular, the variable $\mathbf {w}$ is generally called the angle and $\mathbf {J}$ 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 $S$ in proper separated coordinates $q_{i}$ . PtolRek (talk) 20:44, 15 October 2010 (UTC)[reply]

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]
