I have decided to run a Piazza page for our course. Here is the sign-up link: piazza.com/ubc.ca/winterterm22016/math221sec203
For those who are not familiar with Piazza:
Piazza is an online gathering place where students can ask, answer, and explore 24/7, under the guidance of their instructors. The quicker you begin asking questions on Piazza (rather than via emails), the quicker you’ll benefit from the collective knowledge of your classmates and instructors. We encourage you to ask questions when you’re struggling to understand a concept—you can even do so anonymously.
