Welcome to Differential Equations.
In these course pages you will find the course syllabus and a weekly schedule of assignments. Additionally, I will post fundamental definitions, axioms, theorems or interesting ideas developed in class. Remember that the class notes will be the most comprehensive and your primary reference.

Daily assignments are listed below. Assignments can be added, deleted or modified as appropriate. Please note that there will be a quiz given each week, but may not be announced!
