Talk:Examples of differential equations

examples of what?
This page doesn't say what these examples are used for, just provides a list of equations. Is that really what should be done? FrozenPurpleCube 15:36, 14 March 2007 (UTC)

I, too, don't really see what the point of this page is. D-- (talk) 01:58, 27 March 2008 (UTC)

I also don't see the point of this page. I expected a list of famous differential equations, not general solutions to the simplest cases of differential equations. It appears to me that it is an expansion of what the section here, http://en.wikipedia.org/wiki/Ordinary_differential_equation#Examples should have been. I propose adding some portions of this page to that section and deleting the rest. This section, http://en.wikipedia.org/wiki/Linear_differential_equation#First_order_equation, already has some of the information on this page. Chaimike (talk) 03:19, 22 February 2009 (UTC)

Separable DEs
I thought equations in the form $$\frac {dy}{dx} = f(x)g(y)$$ were also considered separable and is solved by $$\frac {dy}{g(y)} = f(x)dx$$ and thus $$\int\frac {dy}{g(y)} = \int f(x)dx$$ Obscurans 19:39, 31 May 2007 (UTC)


 * Someone's addressed this in the article by specifying that the example given is both separable and linear (which your example is, only if $$g(y) = y$$.) I consider that a poor correction, though: equations that are both separable and linear may also be solved by using an integrating factor, and so the example doesn't show the power of separability.  Anyone care to rewrite?  -- Heath 198.82.23.162 (talk) 19:46, 22 January 2010 (UTC)


 * Fixed by adding a new section 71.56.238.250 (talk) 08:55, 9 October 2011 (UTC)

Deletions of "commercial" examples
On October 7, 2011 Byblon33 has simply deleted several MATLAB symbolic codes, citing "commercial examples", at the same time keeping references to WolframAlpha. First, WolframAlpha is as "commercial" as MATLAB. Second, and most important, these deletions do not appear to be justified. These MATLAB codes are very useful to illustrate the theoretical derivation, and some are not so trivial. I hope that they are put back. 71.56.238.250 (talk) 08:55, 9 October 2011 (UTC)


 * I was just contemplating removing the links to WA, thought I'd check here first. It definitely looks like an advert. The MATLAB code could be OK if it did not require packages (was this the case? I don't know), as the language used in .m files is not necessarily commercial. 86.154.152.170 (talk) 01:29, 26 November 2013 (UTC)
