Calculus reading for 2-27

If you look at the course calendar you will see that you need to read section 2.4 for Monday the 27th. I realize, however, that many of you still don’t have textbooks. Since I forgot to scan the section yesterday, I’ll give you an option. You can read section 2.4, or you can watch this video instead.
