[edit] Comment from 62.252.64.14

I dont understand this please can someone explain simpler? - Posted by 62.252.64.14 18:46, 30 Dec 2004 (UTC) (moved here from article)

[edit] Are all coefficients unit-less?

All of the coefficients I can think of are unitless. Is this part of the definition of a coefficient when used in equations for physical systems? Are there exceptions? Or am I just wrong?

E_0 = m c^2.

the proportionality coefficient between rest energy and mass is c^2 which is not unitless. --MarSch 16:42, 16 Jun 2005 (UTC)

As far as I can tell, the mathematical definition should imply that coefficients are unitless, however, the physical sciences have been using "coefficient" for factors that include dimensions for a long time, where "constant" or "factor" would be a more informative term. —Preceding unsigned comment added by 58.107.199.33 (talk) 05:27, 23 October 2007 (UTC)

[edit] coefficient of a polynomial

"coefficients" of vectors are called coordinates. Perhaps we should convert this to a list of coefficients. --MarSch 16:45, 16 Jun 2005 (UTC)

[edit] Whoa....

OK, I'm no math genius, and so this article makes NO SENSE whatsoever. Define it so that people who don't know what the word means can figure it out (they're the one's who want to know, after all). In 4x, is the 4 the coefficient? If so, just say that. Please. Cut down on the confusion level. Twilight Realm 21:26, 12 October 2005 (UTC)

See Encarta's definition for an example of a good definition. After the summary, then you can go into the details. Twilight Realm 21:33, 12 October 2005 (UTC)

[edit] MathML?

I guess the formulas should be converted to MathML some time. Just suggesting it here. (BTW, I agree with making the article summary a bit simpler) --Jeremy 00:16, 6 March 2006 (UTC)

[edit] translation-request

Can anyone read japanese version of this article? If one can read and think it is useful, then translate it, please. thank you.--218.251.73.134 07:10, 23 March 2006 (UTC)
