Textbook:

• W. Boyce and R. DiPrima, Elementary Differential Equations (9th edition); Wiley, 2009.


• You are expected to read the sections of the textbook we cover every week as we proceed through the course.


• Here are some notes on Linear Algebra that we will also discuss in class: Notes on Linear Algebra

Online java applets:

• Java applet for plotting direction fields for a single ODE, found on the webpage of Robert B. Israel at UBC


• A java applet for simulating (damped) harmonic oscillators, found on the webpage of the Acoustics & Vibrations Laboratory at the University of Illinois at Chicago


• Another java applet for simulating (damped or forced) harmonic oscillators, found on the webpage of Aaron Heap at SUNY Geneseo


• Java applet for plotting direction fields for 2 by 2 autonomous systems, found on the webpage of Robert B. Israel at UBC


• Another Java applet for plotting direction fields for 2 by 2 autonomous systems, by Scott A. Herod at Rutgers


• Yet another Java applet for plotting direction fields for 2 by 2 autonomous systems, by Scott A. Sarra of Marshall University

Grading Scheme:

• Final Exam: 200 points.


• Two mid-term Exams: 100 points each, held in class on October 15, 2012 (Monday) and on November 19, 2012 (Monday).


• Quizzes: 10 points each. These are to be held every Thursday during your recitation (unless otherwise specified). These will be about homework problems that are assigned the previous Thursday (see below). The two lowest scores will be dropped.


• Maple Labs: 10 points each. There will be 5 of them throughout the semester (the first being lab 0 which will not be graded). You can find the instructions and the seed files here. They will typically be due two weeks after they are assigned during the recitation.


• Lab 0 is due Sept 20.


• Lab 1 is due Oct 4.


• Lab 2 is due Oct 25.


• Lab 3 is due Nov 15.


• Lab 4 is due Dec 6.

Homework:

• Homework will be assigned every Thursday. While this will not be part of your grade, you are encouraged to do as much of that in as possible. In addition, you will be quizzed about them the next Thursday in class.


• All homework will be assigned from the textbook unless otherwise specified.
