This syllabus is subject to change. We will make every effort to keep to it, but snow days and other disruptions might require changes. Do not make travel plans that would require you to miss class, particularly classes near exam dates.

Readings are sections in Zill First Course in Differential Equations with Modeling Applications, 10th edition. If you use another text, look up the lecture topic in the table of contents or index.

Lectures without a specified topic are buffers for the inevitable lag. Homeworks are due in recitation on most Thursdays.

Please refer to policies for specifics on handing in homeworks, exam procedures, etc.
