Nuts and bolts about the class:
- The course information handout, including the course description, course requirements, grading policy, and prerequisites.
- The departmental Math 221 course syllabus, including the homework assignments for the semester, in PDF format. We will follow the schedule in the syllabus above as much as possible, but we'll certainly have to make some adjustments throughout the semester.
- Some pointers on how to succeed in diffeq's (or any math) class.
Graphics shown on overhead transparencies or on the computer display during class:

Supplemental handouts and review sheets, in PDF format:
- Information on plotting slope fields for a single first order DE with Maple.
- A quick guide to sketching direction fields.
- A summary of basic integration formulas.
- A summary of useful formulas for exponential, log, and trig functions.
- Information on plotting phase plane direction fields for a system of first order DE's with Maple.
- A quick guide to sketching phase planes.
- Homogeneous linear systems and the phase plane, together with the 9 direction fields.
- The table of Laplace transforms.
