Welcome!
editHello, R.zalman, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your recent edits to the page Catenary did not conform to Wikipedia's verifiability policy, and may have been removed. Wikipedia articles should refer only to facts and interpretations verified in reliable, reputable print or online sources or in other reliable media. Always provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles.

- Thanks JBL for the welcome and the explanation. I'll make sure I'll follow guidelines in the future. (R.zalman (talk) 11:08, 3 February 2021 (UTC))
- You are very welcome (and my apologies for the delayed response). The local culture here is tricky and can take getting used to! (In particular, many new math editors expect "here is a proof" to be the standard for adding material; I think that back in the early days, when Wikipedia was very sparse, it would have been, but that now the principle that material should be based on reliable sources is more heavily policed, even when correctness is not in doubt.) I hope that you continue to contribute. One question worth considering is whether some version of the derivation you posted can be found in any reliable sources (e.g., textbooks on calculus of variations). All the best, JBL (talk) 15:09, 9 February 2021 (UTC)
