Merger proposal[edit]

Should local linearity be merged into differentiable function? In the context of analysis, "locally linear" is a synonym for (and possibly the best way of thinking about being) "differentiable". I don't think much of the content at local linearity is useful: it would mostly be adding a sentence somewhere in this article and turning local linearity into a redirect. — Preceding unsigned comment added by Xnn (talkcontribs) 16:26, 28 July 2012 (UTC)

No definition?[edit]

I think the most important part of the article is missing: There is no where in the article a formal definition of differentiability of a function over a point. Or over his domain.Santropedro1 (talk) 23:07, 4 May 2013 (UTC)


The intro says "For a function of several real variables, there is no notion of derivative." How is the Jacobian matrix not a "notion of derivative"? I don't think the line does anything else except confuse. Tomtheebomb (talk) 05:37, 25 January 2014 (UTC)
