Professor Anna Cox's VIDEOS that go with the Learning Guides NOT REQUIRED but for additional help:

Chapter 2 Learning Guide  In my videos, I talk through how to solve the written problems and give additional important information.  (Typo on 2.5 #7 both equations should be cubed)(2.6 answer of 2d should be (neg infinity, -1) union (-1, infinity)).
