Trigonometry and WikiProject Mathematics
Hi, I noticed your recent edits at Trigonometry and I thought you might be interested to know about the WikiProject Mathematics which I am attempting to revive. The basic idea is to create a place where people can discuss various aspects of creating mathematics texts on a wiki, such as "How do I get this latex to display correctly?", "How do I make nice pictures?". Also I imagine some amount of discussion of our overall organization, content, etc will be discussed (if it ever takes off). Thenub314 (talk) 15:30, 12 October 2010 (UTC)

Trigonometry/A Square Wave in Sines
I started the page Trigonometry/A Square Wave in Sines. I wanted to give a quick introduction to Fourier series assuming mostly just a background in calculus. So I have thus far avoided words like basis, Hilbert space, etc. But still tried to motivate why you might be not so impossible to believe a general function could be a sum of trig functions. Anyways I thought you might want to take a look, and make minor or major changes depending on your taste. Mostly I wanted to see how I might generate an animated gif which I haven't done before.

 * Thanks. I had noticed, and it is great to have your help with this book.  My priority is on Book 1, not that I won't work on Book 2, as overall trigonometry is not going to be noticed until Book 1 has featured status.  I am not sure about animated graphs - nice but perhaps a little gimmicky - they will need a fall-back for printing.  Animated graphs also could take up a huge amount of time tweaking them.  The Gibbs overshoot I would like zoomed in on the area of interest, and I think the graphs on Trigonometry/Graphs_of_Sine_and_Cosine_Functions with the thicker lines look smoother and better.

Modular Arithmetic: So Easy a Caveman Can Do It
I really believe that a number theory book, with a particular focus on modular arithmetic, would be something in particular interest for both of our fields--you, computer science, and me, mathematics education. The title can be changed; it was just something silly I made on the spot as I heard a Geiko commercial playing in my sister's room. The Scope of the project: ---Part 1- -what is a modulus? -modular arithmetic -problem solving with modular arithmetic -fermat's little theorem and euler's theorem -wilson's theorem -chinese remainder theorem -problem solving using those theorems -for enthusiast's:                 -sophie germain theorem -quadratic reciprocity -quadratic residue -primitive root modulo p                 -legendre symbol -problem solving using the above -Part 2-- -polynomials mod p (irreducibility) -Hasse-Minkowski Theorem -p-adic numbers -Hensel's lemma (lifting lemma) -problem solving with above -Newton Polygon of a polynomial -Eisenstein's Criterion -No Name Criterion (polynomial a_n*x^n+....+a_0 is irreducible if |a_n-1|>|a_n|+|a_n-2|+...+|a_0|) I'm not sure if it has a name, but I remember it being called the no name criterion by several people

This is huge and I think it can be split in half. --User:Shrig94


 * OK we're rolling. Great that you started the book, just needs some more planning and content.  Can do planning on the discussion pages.  Diagrams will be important and need to be planned early. JamesCrook (talk) 21:49, 15 November 2010 (UTC)

Trigonometry
Thanks for your note. I haven't finished reading all the pages yet, and when I have done I may want to suggest alterations in style and ordering. But my main concern at present is to fill in some obvious omissions and add extra material; if this starts unbalancing the structure, we may need to create another volume.--Wisden (talk) 09:46, 3 December 2010 (UTC)

Thanks for the thanks
Glad that my contributions are useful. I think that the sort of material in Trigonometry Book 2 is far too neglected.--Wisden (talk) 08:45, 6 January 2011 (UTC)


 * I agree about book 2 material being far too neglected. The whole idea of fluency with algebraic manipulations and geometry, the idea that it might be fun, seems to have passed too many people by.  There are many beautiful simple results with circles and triangles, and working with them, before one has reached calculus and complex variable, is much needed practice at algebra and geometry. --JamesCrook (talk) 18:01, 6 January 2011 (UTC)

Editorial control
Nice find! This page wasn't linked or placed in a category and so even a pretty experienced Wikibookian like myself wasn't aware of its existence. Glad you found it as I've now got it tagged. – Adrignola discuss 22:32, 15 January 2011 (UTC)

"For enthusiasts"
OK, I've added a bit about true north and magnetic north to the compass bearings page.

I must admit I haven't been looking at current syllabi. Besides anything else, we'd need to consider every syllabus in every country, or at least every English-speaking one. I just thought about what I believe people ought to know. If "for enthusiasts" is the wrong place, and I see your point, by all means let's restructure. We could even contemplate two books, one a comprehensive course and one focused on certain syllabi, similar to the books listed in Subject:Computing, which include A-level Computing and even A-level Computing/AQA.

Angles of elevation do seem to be something that people ought to know. They are, however, useful as a pedagogic exercise, and could be lumped together with Worked Example: Area of a Roof and, which surely are likewise "real-world applications".

So in summary, I want to keep angles of elevation, but am not fussed where it is put.--Wisden (discuss • contribs) 21:41, 5 February 2011 (UTC)

Handbook of Management Scales
Hello James, I wonder if you could have a short look over my English used at the start page of the Handbook of Management Scales, since English is not my first language. Best regards, Andreas 92.231.85.214 (discuss) 23:41, 9 February 2011 (UTC)
