Intro
The introduction states that the exponential function is the only function equal to its derivative. This isn't quite right; and constant multiple of the exponential function works too. I'll try to find a way to make it correct without being ugly. Warren Schudy 17:14, 9 January 2008 (CST)
- Corrected. Olier Raby 05:18, 13 March 2008 (CDT)
some equations too small
I suggest reformatting the equations stuck in the text of paragraphs 1 and 4, because they are really to small to be easily read. Also, be sure to indent equations with the use of a leading semicolon or two. David E. Volk 10:20, 24 February 2008 (CST)
- Done. Olier Raby 05:18, 13 March 2008 (CDT)
renaming of this article
We will need to rename this article because User:Ro Thorpe is going to make an article about the letter E/e. My immediate thought is to rename it e (exponential base), but input from mathematicians would help. If possible, I would like the primary author to make the move. David E. Volk 13:25, 29 February 2008 (CST)
I'm not totally happy with "e (exponential base)", but it's the best I've heard so far. This isn't a critical decision; someone who knows how to move subpages should just do it. We can always move it again later if we get a better idea! Warren Schudy 14:38, 29 February 2008 (CST)
- I'd suggest e (math) or e (mathematics), and make sure Ro puts a disambiguation link to this article at the top of his article about the letter. Anthony Argyriou 15:54, 29 February 2008 (CST)
- I moved the article and subpages to e (math), created the disambiguation page at E (disambiguation) and made a stub article, with all subpages also for E (letter). David E. Volk 16:37, 29 February 2008 (CST)
- I believe it is better to name it e (mathematics). Olier Raby 05:19, 13 March 2008 (CDT)
Is equation missing a summation sign?
There are many ways to define e. The most common are probably
The above equation would have a value of 1 for n=infinity, suggesting that a summation symbol over n is missing. David E. Volk 09:57, 13 March 2008 (CDT)
