Exceptions can only be accepted in case of time conflicts with other courses, or serious illness with a physician's certification.

Computer Lab: The availability of computer packages such as Maple, Mathematica, Mathcad and Matlab provides an opportunity to easily conduct numerical experiments and to tackle realistic and more complicated problems. The lab classes will be used with two goals in mind: (a) demonstrate concepts seen in class, (b) allow you to become familiar with computer software to solve differential equations. In this course mainly Matlab will be used. In addition to the packages mentioned above, many illustrative examples can be found at Addison-Wesley's Interactive Differential Equations website. You are encouraged to explore these examples as you proceed in the course.

There will be 2 computer labs in Weber 206:   --  Regular class on other days.
Lab 1:
 Friday, September 4, 2015
Lab 2:
 Friday, September 25, 2015
On these days the class will meet in Weber 206. You have access to the lab at other times as well, as long as it is not in use by another course. In the first lab session you will be given a username and a password for the computers in the lab. Do not share this information with others. More lab information: click here (pdf) and here.
