Announcements:

Exam 3, NOW DELAYED TO WED MAY 05.
The course notes can always be found here at the top of the page. (Last revision: Tue Apr 27, 6:00pm.)
Permalinks for the course:
Our weekly problem sessions will be held online every Friday, from 10:00am-noon. We'll use the same Zoom link that we use for office hours.
Here's a getting started video for Gradescope, along with Gradescope's official guide to scanning multi-page documents into PDF and a related how-to video.
If you're interested in typesetting math, the system I use to make my handouts is called LaTeX, and it can be downloaded for free (in Windows format) at http://www.miktex.org. If you own a Mac (system OS X) or a Linux computer, you already own a copy of this program, as it's been a standard Unix program for about 20 years. And for our purposes, the key point is that under any system, LaTeX can produce pdf output that is ideal for online homework submission.

LaTeX is well worth learning, if you have some free time; it's used for manuals and technical reports throughout nerd-dom. For self-study, I highly recommend the LaTeX book by Leslie Lamport, which you can purchase here.
