Talk:Cobweb plot

I propose editing the "Interpretation" section as follows, my edit in brackets, for further clarification:

"On the cobweb plot, a stable fixed point corresponds to an inward spiral, while an unstable fixed point is an outward one. [It follows from the definition of a fixed point that these spirals will center at a point where the diagonal y=x line crosses the function graph.] A period 2 orbit is represented by a rectangle, while greater period cycles produce further, more complex closed loops. A chaotic orbit would show a 'filled out' area, indicating an infinite number of non-repeating values." Jw116104 (talk) 23:53, 23 September 2010 (UTC)

I think there should be one more column after the definition,method and interpretation columns names as applications of cobweb plot.The main use of cobweb plot is in military purposes.Detailed description is in http://escholar.salve.edu/cgi/viewcontent.cgi?article=1015&context=pell_theses.This column is very useful because everybody should know where actually the concept of cobweb plot is used and its major uses. Another important application is that it is used to study the behaviour of solutions to recurrence equations.Detailed description can be found out in http://www.wseas.us/e-library/conferences/2010/Tunisia/EDUTE/EDUTE-09.pdf. —Preceding unsigned comment added by Saichow2k (talk • contribs) 15:20, 24 September 2010 (UTC)

I propose adding visual examples of behavior near a fixed point x for several ranges of the derivative f'(x). In particular, I propose adding examples of behavior for f'(x) in the following intervals: (-\infty, -1), (-1, 0), [0, 1), and (1, \infty). The behaviors are: Diverging spiral, converging spiral, converging (but not spiraling), and diverging (but not spiraling).Nm160111 (talk) 15:44, 11 September 2012 (UTC)

Possible 'Not to be confused with'?

I came here looking for something like this: http://img72.imageshack.us/img72/8048/oparin.jpg

It looks like a cobweb IMO, so I'd expect more people to look for 'cobweb graph' or something similar and end up here instead. 80.132.51.147 (talk) 20:28, 10 July 2014 (UTC)

Don't even DREAM of saying what the logistic map IS . . .

. . . in the graphs that mention it in the right-hand column. Why would anyone editing Wikipedia want a website visitor to actually understand something?

First caption: "Construction of a cobweb plot of the logistic map, showing an attracting fixed point."

Second caption: "An animated cobweb diagram of the logistic map, showing chaotic behaviour for most values of r > 3.57."

It is true that the second caption has the words "logistic map" as a link to its article. But just how much trouble is it to write y = Kx(1-x)?Daqu (talk) 01:32, 12 March 2015 (UTC)
