#LIST ALL THE ATTENDANCE QUESTIONS FOLLOWED BY THEIR ANSWERS

1) Using Maple, find the stable fixed points of x -> 3.6x(1-x) and stable fixed points by hand

f:=3.6x-3.6x^2
SFP(f,x)

There are no stable fixed points. Maple generates an empty list. 
There are two unstable fixed points.

f'(x) = 3.6 - 7.2x
f'(0) = 3.6 (unstable)

2) What is the other Feigenbaum constant?
There are two Feigenbaum constants: the delta constant and the alpha constant. Both represent the ratios in a bifurcation diagram for non-linear maps.
