If everything was typed correctly, a main window and several other windows appear. Three of these other windows are of interest:
Note: If any of the windows appear ``dead'', then iconify them and reopen them. This happens on some window managers.
The Main Windowhas all the menus etc and the one we will work from the most.
Click on and then or tap and the equations will be iterated for 200 steps. Click on ot tap to change the window size. Fill in as follows
In the Initial Data Window, change the initial value to .01 and click on .
Change the parameter r from 2.5 to 3.2 in the parameter window and click on . Note that you have a period 2 solution. This may be hard to see with this many points. Rewindow to expand around a small region, for example
Now change r to 3.5. Click on or tap to clear the window and click on either in the Parameter Windowor tap in the Main Window. What do you see now? A period 4 solution should be clearly evident. Choose r=3.75 and look again. You might want to make the window cover more iterates.
Exit the simulation now by clicking on
