- Homework #5 . . . Solutions: page 1,
page 2.
Addendum to solution #5; I forgot to include the final-state
diagram. It contains the curves in the bifurcation diagram only for the stable periodic points. So, the
final-state diagram will contain the line segment along the x-axis from -1 to 1 (where the fixed point x=0
is stable), the period 1 branches leaving from the point 1 will not be there (they are always unstable),
the period 2 branches leaving from -1 will appear until -2.2 (where the new period 2 orbits appear), the new period 2
orbits will apppear on the final-state diagram from -2.2 until around -2.5 (when they become unstable).
- Marking scheme: #3, 6 marks; #5, 9 marks; #6, 2 marks; #7, 4 marks; #8d, 4 marks; #9, 3 marks. 28 marks
in total.

#10abcd, 6/4/4/2 marks; #14, 4 marks; #16, 4 marks. 49 marks in total.
