CC MATHEMATICS   CHAOS AND CALCULUSSYLLABUSASSIGNMENTS

Assignment 9/10:  due Thursday 9/12 at 9AM

Turn in individual solutions. You may work together in solving the problems, or get help from others, but the final write-up should be your own. Do not turn in anything you cannot explain completely.

Calculus p. 95  #32, 34, 37, 40, 42, 44, 47, 57, 67 (you do not need a graphing calculator)
                p100 #4, 12
                p 106 #15

1.  Using the website Bifurcation Diagram Applet, locate a 5-cycle windows in the 
    bifurcation diagram of the logistic map.  Write down the s value where the 5-cycle seems to
    begin, and the s value where 5-cycle appears to break down into complete chaos.  Then find
    a 7-cycle window and a 9-cycle window (try looking to the left of your 5-cycle window), and
    do the same for them.  

Assignment 9/11:  due Friday 9/13 at 3PM

Work in pairs on this assignment.  Turn in one solution for you and your partner.  Make sure both of you contribute and
understand the solutions.

Calculus  p. 126 #25 (do you know the significance of this for statistics?), 26c, 27, 31, 33
                p. 139 #13b, 13h 

1.   A slight variation of the logistic map is given by xn+1=sxn(1-xn2)
    a.  Is the graph of xn+1as a function of xn symmetric about xn=1/2 (try some values on
        opposite sides of 1/2 to test this)?
     b.  For what value of xn is xn+1 maximum?
    c.  Using your answer to b to determine the maximum value s can have and still have
        the dynamics bounded between 0 and 1.   
    d.  Make plots of xn+1as a function of xn for x=1/2, 1, and 2, for xn between 0 and 1.
    e.  For what values of s does this map have a single fixed point?  What is the fixed point?
        Determine whether the fixed point is stable or unstable, and explain why.
    f.  For what values of s does the map have more than one fixed point?  Solve for all fixed points
        as a function of s.  Determine when these fixed points are stable.  
2.  Play Derivative puzzles 1, 2 and 3 at the Differentiation game  website, and turn in rough sketches of the answer grids.
