Homework Assignments for
M408N, Applied Linear Algebra

This page is always under construction, so you should check it regularly.

The written assignments will appear on this page. Some just involve doing book problems. Others are worksheets. The worksheets that are handed out in class (either lecture or discussion) will later appear here in PDF form, but not necessarily immediately.

All written assignments based on the book are to be turned in at the beginning of discussion section, usually on a Monday. Worksheets will sometimes be due at the end of a discussion section (if the main activity for the discussion is working on the worksheet) and sometimes at the beginning (if you mostly worked it on a previous day and were allowed to finish at home).

Online homework is always on Quest. There will be a pre-class and a post-class assignment for each class meeting. The pre-class assignment is due at midnight the night before the class. The post-class assignment is due at 6PM on the day before the subsequent class. In other words, the pre-class assignment for Tuesday is due Monday night, and the post-class is due Wednesday afternoon; the pre-class assignment for Thursday is due Wednesday night and the post-class is due on Monday afternoon.

The class schedule, and hence the schedule of online homework, can be found here.
