[edit] Mathematical proof: proof by contradiction example

Hello! I moved the example you added regarding the division algorithm to the article's Talk page temporarily because it needed some formatting cleanup and also because I didn't think it was the best example for that section. There's already been some discussion regarding how many examples should be in each section. I do think it was a valuable and productive edit, particularly since the division algorithm is very important, but maybe it would be better for the Nonconstructive proof section of the article (which mentions the fact that proof by contradiction is often used). Feel free to discuss this change, either on my talk page or on the appropriate section of the article's talk page. Thanks, and happy editing! --JaimeLesMaths ^(talk!edits) 22:46, 28 October 2006 (UTC)

[edit] Welcome!

[edit] use of TeX

Please compare and contrast these:

= +-,

The first is what you wrote; the second is standard. At least on my browser, the minus sign looks very different, "cos" looks different, the spacing before and after "cos" looks different, the spacing before and after "+" and "=" looks different, "+" and "=" themselves look different, and the comma at the end looks different. Not only does the second look in all respects better, but also the TeX code is simpler, so it's easier to read it when you're editing. Michael Hardy 20:29, 1 December 2006 (UTC)

[edit] More on the use of TeX

And it is good if you do not force TeX to be PNG inline, per the math stule manual, so <math>x^2</math> should not be written as <math>x^2\!\,</math>. If you prefer to see the formulas as images, you can change your preferences to that effect. Cheers, Oleg Alexandrov (talk) 03:03, 5 December 2006 (UTC)
