This video is intended for students who find this material to be difficult, so in the video I proceed slowly and repeat myself a lot. If you find that the video moves too slowly, you can simply try the problems in the Problems document, check the solutions in the Solutions document, and skip to any particular parts of the videos that cover parts of the solutions that you find confusing.
