Your edits in Fundamental theorem of calculus and elsewhere

I have reverted your edits of Fundamental theorem of calculus, which consist essentially in replacing, for the differentiation sign, the italic d by upright d. You argue, without sourcing your assertions, that the upright d is the most common international convention. This has been discussed here, and it appears that most textbook use italic d. Thus your assertions are wrong. Moreover, the Wikipedia manual of style says here: "Some authors prefer to use an upright (Roman) font for dx, and Roman boldface for i. Both forms are correct; what is most important is consistency within an article. It is considered inappropriate for an editor to go through articles doing mass changes from one style to another." Therefore, please, stop to replace italic d by upright d and revert your similar edit of other articles which have not yet been reverted by others. If you continue to try to impose upright d for differentiation, this will be disruptive editing, and you may be blocked for editing. D.Lazard (talk) 18:56, 23 February 2014 (UTC)[reply]
