Welcome
Overdue welcome. Welcome to Wikibooks, יהודה שמחה ולדמן!

 First steps tutorial Wikibooks is for collaborative development of free textbooks.

  Getting help   Made a mistake?   Goodies, tips and tricks
 * Read the Using Wikibooks book for a friendly introduction to the project, or our help pages for more information.
 * You can get friendly help from the community in the user assistance room or our IRC channel.
 * Upload freely licensed files to Wikimedia Commons. You may request permission to upload fair use files locally. Please include author and source information and a non-free use rationale for non-free files.
 * You can restore a previously saved version.
 * Pages should follow the  naming convention.
 * Need to rename a page? Use the move tab (is available once your account is 4 days old - until then, ask for help).
 * To request a page be deleted, add to the top of the page.
 * Was a page you made deleted? Please read the deletion policy, and check the deletion log to find out why. Also check the RFD archives if applicable. You can request undeletion at WB:RFU, or ask the administrator who deleted the page.
 * Please fill in the edit summary and preview your edits before saving.
 * Sign your name on discussion pages by typing &#126;&#126;&#126;&#126;
 * User scripts can make many tasks easier. Look at the Gadgets tab of my preferences; check off the boxes for the scripts you want, and hit save!

You enlarged mathematical symbols
Hello,

you changed formatting of certain pages in Calculus concerning analysis of multiple variables. Could you explain why you did that? Now it's not consistent over the three chapters. --Mathmensch (discuss • contribs) 11:49, 14 May 2017 (UTC) (But I'm glad anyhow that at least one person finds them worth a read, and even a slight modification.)
 * What pages? יהודה שמחה ולדמן (discuss • contribs) 11:51, 14 May 2017 (UTC)

Please don't change the formatting of my wikibooks without seeking council
Hello there, I usually use the European spacing system, which is used in English. Please stick to that, and don't make equations very big, unless you bring up good reasons for doing otherwise. --Mathmensch (discuss • contribs) 15:04, 24 March 2018 (UTC)
 * Which equations are big? יהודה שמחה ולדמן (discuss • contribs) 18:07, 24 March 2018 (UTC)
 * Calculus/The chain rule and Clairaut's theorem --Mathmensch (discuss • contribs) 19:25, 24 March 2018 (UTC)
 * Now I remember. So I just erased that font-size coding.
 * But what is the European spacing system? What is the point of using the long coding? יהודה שמחה ולדמן (discuss • contribs) 19:46, 24 March 2018 (UTC)
 * By the European spacing system, I mean that the first sample is correct, and the second isn't:

This is a random sentence. Here is another. (CORRECT) This is a random sentence. Here is another. (WRONG!)
 * And please don't troll me. I don't have any time. Look at University_level_mathematics, this is my ToDo list. It's not short, agree? --Mathmensch (discuss • contribs) 19:50, 24 March 2018 (UTC)
 * So the problem was not at all with my LaTeX editing? Or should I avoid that too?
 * Now that I have seen your topic-tree table, I hope to see soon more about the geometrical meaning of "complex differentiation". יהודה שמחה ולדמן (discuss • contribs) 21:40, 24 March 2018 (UTC)
 * Essentially, it means that you are complex differentiable iff the Cauchy–Riemann equations hold. The latter may be translated into the usual geometric intuition of partial derivatives. (You can also look into Bornemann's book, which illustrates quite clearly how holomorphic maps are locally preserving a right angle, but I won't discuss this in Complex Analysis in detail.) --Mathmensch (discuss • contribs) 08:34, 26 March 2018 (UTC)
 * Should I avoid LaTeX editing too on your pages? יהודה שמחה ולדמן (discuss • contribs) 21:22, 4 April 2018 (UTC)
 * Do your editing as long as it's sensible (e.g. correcting a mistake). Don't make equations big. --Mathmensch (discuss • contribs) 11:58, 5 April 2018 (UTC)
