Added a phrase that clarifies the nature of the extended exterior differential system

| Aug 9, 2015 at 3:51 | comment | added | Ali Taghavi | Thank you again for your answer.I need more background to understand it.But just a question:Am I mistaken to think that the expression of $\Delta$ in terms of $X_{i}$ depends sensitivly on "Orthonormality" of the frame?So Is my question in the post equivalent to the same question with etra restriction orthonormality of X_{i}?I think 2 answers to this questions are assuming this extra restriction. | |
