Login here to run Matlab and Maple remotely. For Maple, go to Standard Software -> Computational Packages
Or, use the web applet version.
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
