Your edits in Derivative
Thank you for editing the article Derivative. Although preceding edits have been reverted by another user, you are reinstalling them, without discussing on the talk page if they are convenient. As I agree with the other editor that a single example is sufficient at this place, I'll revert you again. I have to warn you that continuing to insert your example(s) without discussing on the talk page and reaching a WP:consensus may be considered as WP:edit warring and may lead to block you for editing.

About your edits, some more comments are needed. Firstly, please use the button "show preview" at the bottom of the edit window. It allows to save your edits only when they are ready to be published. This makes easier for the other editors to know what has been done. For the same reason, save them with an edit summary.

Beside the fact that one example suffices, your example with the natural logarithm is not convenient here as WP:too technical. In fact, it is unbelievable that somebody, who knows of natural logarithms, does not know what is a derivative. In fact, the natural logarithm is usually defined as the antiderivative of the function 1/x. If not defined in this way, it is defined as a continuous function satisfying the identity log(xy) = log(x) + log(y), and having the derivative 1 for x = 1. All the notions that you use in the proof of your example need the notion of derivative to be proved. This is not surprisingly, because only the derivative allows to distinguish the natural logarithm from the other logarithms. D.Lazard (talk) 09:24, 4 February 2014 (UTC)


 * I agree with D.Lazard. The logarithm example requires much more technique than the article has developed at that point.  All that a reader needs to understand the article up until that point is elementary algebra and the notion of a limit.  Understanding the derivative of the logarithm requires knowing about antiderivatives or Taylor series (because log x can also be defined as the inverse function to ex, which can be defined as a Taylor series; then one can apply the rule for derivatives of inverse functions).  We can't expect the reader to know about these things yet.  The only acceptable examples at that point in the article are very, very, very simple, and the derivative of the logarithm isn't simple enough.  Ozob (talk) 15:02, 4 February 2014 (UTC)

Please refrain from changing genres, as you did to Derivative, without providing a source and without establishing a consensus on the article's talk page first. Genre changes to suit your own point of view are considered disruptive. Please discuss the issue on article's talk page to reach a consensus if you want your edits to be there.

Wikipedia and copyright
Hello Arpan Mathur. All or some of your addition(s) to National Talent Search Examination has had to be removed, as it appears to have added copyrighted material without permission from the copyright holder. While we appreciate your contributing to Wikipedia, there are certain things you must keep in mind about using information from your sources to avoid copyright or plagiarism issues here.


 * You can only copy/translate a small amount of a source, and you must mark what you take as a direct quotation with double quotation marks (") and cite the source using an inline citation. You can read about this at Non-free content in the sections on "text". See also Help:Referencing for beginners, for how to cite sources here.
 * Aside from limited quotation, you must put all information in your own words and structure, in proper paraphrase. Following the source's words too closely can create copyright problems, so it is not permitted here; see Close paraphrasing. (There is a college-level introduction to paraphrase, with examples, hosted by the Online Writing Lab of Purdue.) Even when using your own words, you are still, however, asked to cite your sources to verify information and to demonstrate that the content is not original research.
 * Our primary policy on using copyrighted content is Copyrights. You may also want to review Copy-paste.
 * If you own the copyright to the source you want to copy or are a designated agent, you may be able to license that text so that we can publish it here. However, there are steps that must be taken to verify that license before you do. See Donating copyrighted materials.
 * In very rare cases (that is, for sources that are public domain or compatibly licensed), it may be possible to include greater portions of a source text. However, please seek help at the help desk before adding such content to the article. 99.9% of sources may not be added in this way, so it is necessary to seek confirmation first. If you do confirm that a source is public domain or compatibly licensed, you will still need to provide full attribution; see Plagiarism for the steps you need to follow.
 * Also note that Wikipedia articles may not be copied or translated without attribution. If you want to copy or translate from another Wikipedia project or article, you can, but please follow the steps in Copying within Wikipedia.

It's very important that contributors understand and follow these practices, as policy requires that people who persistently do not must be blocked from editing. If you have any questions about this, you are welcome to leave me a message on my talk page. Thank you. — Diannaa (talk) 23:04, 31 July 2016 (UTC)
