Old Assignments

Week 1: Several of you might be interested in forming a Team and entering the Math Modeling Contest. This is a national competition, where a good performance wins glory and good offers to graduate schools. Interested students should contact Dr. Kristin Duncan. You should begin by reading the Introduction section in the lecture notes, then read p. 1-7 in the text and the Logistic Growth notes from Math 121.There is a hyperlink to the Excel spreadsheet of the material presented in class on fitting discrete dynamical systems to yeast populations. The homework assignment is on p. 7: Problems 2, 3, 4, 5, 8, 9, 10 (Modify Problem 3 c to be the sequence {1, 3, 7, 15, 31, ...}The solution to the given problem requires a cubic equation, so is not reasonable, but bonus points will be given for anyone finding the solution.) and Project 1.1. These problems are due Thursday, Feb. 1. In addition, there is a problem directly associated with the lectures, which will be due Thursday, Feb. 8.

Week 2: Note the change in Problem 3c above. This week continues the material on discrete dynamical systems. Read the lecture notes on Nonlinear Dynamical Systems and U. S. Population. The homework assignment is a problem directly associated with the lectures on Logistic growth and Ricker's model, which will be due Thursday, Feb. 8. More homework associated with Logistic growth and Nonlinear dynamical models are found through the hyperlink and are also due Thursday, Feb. 8. In addition, there are homework problems for the Nonautonomous dynamical models found through another hyperlink and are due Thursday, Feb. 15.

Week 3: Read the lecture notes on Nonlinear Dynamical Systems and U. S. Population. The homework assignment is a problem directly associated with the lectures on Logistic growth and Ricker's model, which will be due Thursday, Feb. 8.
