Homework Assignments for

M408N, Applied Linear Algebra

This page is always under construction, so
you
should check it regularly. Assignments with the **due date**
in **bold face** are set in stone.
Other assignments are still tentative.

The homework is due **twice a week** in lecture. The homework has two
parts. One part is problems from the book, which should be written up
and turned in at lecture. The other part is on Quest, and should be done
online **by midnight the night before the lecture**.

The written assignments will appear on this page. The Quest assignments
will appear on (you guessed it) Quest. The very first Quest assignment is
an assessment of your precalculus skills. You will receive an email
with more information about this. The time window is from
noon Fri 8/26 - 10am Mon 8/29.
