Spring 2018

All assignments are due in class on the date shown.  On the first page of homework assignments, write a list of any assigned problems that you did not finish (it should be a short list).  Show your work.  I strongly encourage you to work in groups, but you must write up the results yourself.

By 9:00 on the morning of the seminar date (if there is one), email me a listing of:

Date due Assignment
Wed 1/17 Math questionnaire
Wed 1/24 (seminar day Mon 1/22) Experiment 3.6 (p. 25), for the doubling function D only (the Maple worksheet iterateDoublingMap.mw may be helpful, or Excel, or this applet if Java works on your computer)
3 (p.26) #1, 3, 5-10, 13, 14
4 (p.34) #1, 5, 6, 7
Fri 2/2 (seminar day Wed 1/31) 5 (p.50) #1(a,c,j,k), 2(a,b,d), 3, 4(a,b), 5, 6

Let cn be the red blood cell count at time n (measured in cells per microliter).  If
cn+1 = (1 − a)cn + b(cn)r e^(−scn)  and
b=1,100,000, r=8, and s=16, show that there are two stable and one unstable fixed points when a=0.2.  How do you interpret this result in terms of the red blood cell count?
Fri 2/9 (seminar day Wed 2/7)
6 (p.67) #1(a,b,e,f,j), 2-8, 10
Fri 2/23
(You don't have to turn these in, but you're responsible for the material on the midterm.)
7 (p.80) #1-3, 16-18
