This applet performs cobwebbing for a first-order difference equation [math]x_{n+1} = g(x_n)[/math].

Enter the function [math]g(x)[/math] in the box, and choose an initial condition [math]x_0[/math] by dragging the point on the x-axis or typing a value in the textbox.[br][br]Click 'Iterate' to perform the next step in the cobwebbing.[br][br]Zoom and move the view using the buttons at the right, or hold 'Shift' and click & drag in an empty region.[br][br]You can click 'Reset' to delete the cobwebs, or enable 'Show details' to see the cobwebbing process step-by-step.[br][br]Based on an applet from Math Insight: [url]http://mathinsight.org/applet/function_iteration_cobweb[/url]
