Talk:Derivative (mathematics)

I think I may have dumbed this page down too much? I resorted to using worked examples in some sections because as far as I know that is the only way one really understands what's going on. Might be better suited for Wikibooks, but if it doesn't belong here it can be rewritten. -- 124.171.194.6 (talk) 05:56, 8 May 2010 (UTC)

And yes, I know this WP is designed to be simple English, not stupified in general. I created this per request at w:Talk:Derivative which says it's hard to understand the concept, not that its English is too complex (although that might be the case. -- 124.171.194.6 (talk) 06:05, 8 May 2010 (UTC)

Also, this page could use some images, particularly explaining why the derivative of f(x)=2 is 0 (doesn't increase). I have some graphing software, but don't think I could make it presentable for the encyclopedia, and I couldn't upload it as an anon. -- 124.171.194.6 (talk) 06:05, 8 May 2010 (UTC)

Thank you for your hard work. I agree with you, but why don't you go and ask in Simple Talk? Belle ^{tête-à-tête}

As far as the appropriateness of readability levels, it looks fine to me. Also, FYI, all uploads are done through the Wikimedia Commons and not directly to this Wikipedia. In any event, thank you for working on a sorely underrepresented area of this wiki (mathematics). Kansan (talk) 06:07, 8 May 2010 (UTC)

"For functions that act on the real numbers, is the slope of the tangent line at a point on a graph"... what?
