August 2020
Hello, I'm DVdm. I noticed that you made a change to an article, Continuous function, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 15:41, 31 August 2020 (UTC)

Edit warring
You currently appear to be engaged in an edit war&#32; according to the reverts you have made on Limit of a function; that means that you are repeatedly changing content back to how you think it should be, when you have seen that other editors disagree. Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus, rather than repeatedly undoing other users' edits once it is known that there is a disagreement.

Points to note: If you find yourself in an editing dispute, use the article's talk page to discuss controversial changes and work towards a version that represents consensus among editors. You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases, it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing. - DVdm (talk) 09:02, 1 September 2020 (UTC)
 * 1) Edit warring is disruptive regardless of how many reverts you have made;
 * 2) Do not edit war even if you believe you are right.

Cauchy-Riemann equation
Please STOP rewriting this page. It is an excellent source for students. I am a physics professor with 40 years of experience and I teach Math methods in Physics. I use this page as a reference for my students. The original text is very didactic and helpful. Yours is not. Please stop messing with it. Chlodvig (talk) 23:52, 2 September 2020 (UTC) Chlodvig
