Notes also available as PDF.
Practice is absolutely critical in this class.
Groups are fine, turn in your own work. Homework is due in or before class on Mondays.
Note that you may email homework. However, I don’t use MicrosoftTM products (e.g. Word), and software packages are notoriously finicky about translating mathematics.
If you’re typing it (which I advise just for practice in whatever tools you use), you likely want to turn in a printout. If you do want to email your submission, please produce a PDF or PostScript document.
