[edit] comments
lagrage did some crazy math problems ". It was Lagrange who developed the Mean Value Theorem. "
I don't like this in the first paragraph. It makes it look as if the mean value theorem was his most important work. Can it pleased be moved lower down in the article ? Theresa knott 14:33 2 Jul 2003 (UTC)
This is a work in progress. Everything but the first paragraph is cut and pasted. If you know of something LaGrange did, then add it in. Also, some argue that the MTV is the most important theorem in calculus. Pizza Puzzle
Can you tell me why you keep in spelling his name LaGrange, rather than Lagrange? See this search http://www.google.com/search?q=lagrange%20site%3A.fr for how the French spell it (and they should know) and this one http://www.google.com/search?q=mathematician+lagrange for the mathematician. Notice how all of the few mis-spellings are on U.S. sites, but the consensus on both sides of the Atlantic by a large margin is "Lagrange". -- The Anome
- According to the MacTutor article, he sometimes signed his name Lodovico LaGrange, in his youth. So it's not really a misspelling as such, although obviously we shouldn't use it. --Zundark 10:40, 19 Oct 2003 (UTC)

- 2 years later... I am reading the book Disquisitiones Arithmeticae and Gauss spells 'La Grange' and 'La Place', but it's the only place I have seen them spelled this way. -ReiVaX 15:47, 20 October 2005 (UTC)
I was watching Star Hunter and they mentioned Lagrange points. Something about orbiting planets. ??? -gbleem
- See Lagrangian point. (This was hard to find from the article, so I'll add it as a see-also.) --Zundark 10:40, 19 Oct 2003 (UTC)
[edit] lagrange's error bound
Does anyone know what is lagrange's error bound?
[edit] Number Theory at risk
I wonder what makes The theory of numbers neglected (in "the neglected but singularly fascinating subject of the theory of numbers").
"Considered the greatest mathematician of the 18th century..." What about Euler? It has to be a close call anyway. And who is doing this considering?
- Actually I'd say that the theory of numbers is not neglected. The Riemann hypothesis, for example, has had a huge amount of work done on it. And I agree, Euler was probably the most important mathematician in the 18th century, and one of the most influental ones ever. --Ignignot 18:40, 6 December 2005 (UTC)
[edit] 24.253.120.206
A user at 24.253.120.206 has been performing many edits recently, which have been largely to restructure the article and add links. If you are performing so many edits, would you mind both signing in, and using the preview button more? --Ignignot 19:06, 12 December 2005 (UTC)
[edit] M.A.T.H (Mathmaticians and Their History)
Surely the above text is superfluous? Tricky 20:40, 14 March 2006 (UTC)
[edit] Greatest of C18?
"... arguably the greatest mathematician of the 18th Century"!? is anyone forgetting Euler? is there really argument about this? -Storkk 10:53, 30 June 2006 (UTC)
- People seem to be agreeing with me (3/3 in talk page) that there's not much argument that Euler was the greatest of the 18th C. I've waited a while for any dissenting opinions, so i'll now try to restructure it. --Storkk 15:14, 4 July 2006 (UTC)

- Actually, this claim is From `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball, the source for nearly the entire article. I also have other references that support this claim. In fact, Euler was considered and, thus, the word "arguably" was inserted in contrast to the references aforementioned. --68.224.247.234 22:19, 16 August 2006 (UTC)
[edit] Isoperimetrical problem
Although Lagrange contributed to a solution of the tautochrone problem, the problem referenced in the article is intended to be the isoperimetrical problem. In fact, the biography is entirely based on `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball. --68.224.247.234 22:20, 16 August 2006 (UTC)
Lagrange indeed solved the isoperimetrical problem. The citation for this is already provided — refer to `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball, which is listed in the references. --68.224.247.234 19:59, 6 October 2006 (UTC)
- ok, so the isoperimetrical problem article needs to be updated to remove the claim that Jakob Steiner solved it, right? Does the book you mention give a reference to a paper that Legrange published? Primary sources are always nicer to have. I guess I'm concerned that some of these old books just repeat incorrect information and/or represent national biases about who should be credited. Wrs1864 23:17, 6 October 2006 (UTC)
