These video files are lectures on the step-by-step solutions to problems found in the end of section exercise sets. They are provided in QuickTime format in two versions: "Small" for slower connections and "Large" for users with more bandwidth. The video files are prepared to intelligently stream, so you may begin playing them before the entire file downloads. A status bar across the bottom of the movie file will inform you as to how much of the movie has been downloaded. QuickTime provides tools for controlling the playback of these videos, including play, pause, volume control, and the ability to step forward and backward. You may also use the slider bar to move through the video.
