Syllabus

 

Announcements

Maple spreadsheet for power series solutions near a regular point. With IE, right-click and save it. IE would change the extension to *.xml for some reason. Change it to *.mw which is the Maple extension.

Lecture Notes for 7.1 - 7.5 (only).

Typical phase portraits (low resolution but readable).

EXAM 1: Thu 09/21, 6:30 - 7:30pm WTHR 104   You can use one sheet of notes, both sides    Covers 5.1-5.4 and 7.1-7.6 without 7.4.    Old Exams        

EXAM 2: Thu 10/12 6:30-7:30pm BRNG 2280    You can use one sheet of notes, both sides    Covers 7.7-7.9 and 9.1-9.3.
