Ordinary Differential Equations (Math 551) introduces and develops its subject, differential equations, which turn out to provide the fundamental concept used in modeling phenomena in Nature. Applications occur throughout the sciences, both natural and social, but also in practical daily life and business. The emphasis of the course is then divided between the underlying mathematics and the various applications.

Starting in week 09/17–21, on the topic indicated in the weekly schedule.
All weekly assignments are due by 5:00 pm of the end of the week indicated and should be submitted via e-mail attachments, or alternatively handed in either to the instructor in hand, left in the instructor's mailbox in ETV#116. Late assignments will not be accepted, except in cases of proven emergency.
Collaboration policy
Collaboration -- but not blind copying -- on the weekly assignments is strongly encouraged; students should use this to learn from each other. All assignments are open text and other sources, as indicated in the textbook listing above.
Presentation and organization
While a neat presentation of the Student’s work is not required for full credit, it certainly makes it easier to assess the quality of the work and give the proper credit due. In all cases, include sketches if they might help conveying the approach or the calculations. Where necessary, include all units and symbols such as the measure of an integral, arrow on a vector, vertical bars for the absolute value of a quantity, for the magnitude of a vector or for the determinant of a matrix, etc.
