Online Materials

There is a variety of online materials that comes with the textbook. They are all accessible from MyLabsPlus, but you have to hunt and gather. I have collected most of the links in one place. You may find others when you are logged into MyLabsPlus. More explanations are at the end of this page.

Explanations

The Online Textbook

This is the entire textbook in online form, but it is much more than that. There are clickable links embedded in it which take you to tutorial exercises and videos. Watch for these icons:

This leads to a video clip where an instructor works out one of the problems. These are the same videos you get by clicking on the links in the video column. Unfortunately these don't work in the computer labs. Someone set it up so that streamed video gets filtered out. You have to watch these at home.

This leads to a tutorial exercise, provided that you have the MathXL plugin installed. This will work in the lab, but on your private machine you have to install the plugin. See instructions below.

The online textbook cannot be saved to your local machine. It is actually a Flash movie. If it doesn't work, try upgrading your Flash plugin.

The Videos

For every section there are several video clips where an instructor solves a problem similar to a problem in the text. If you access the videos from the online textbook you can see which problem he is working on. If you access the videos from the table above, you can browse the videos for the whole section.

The videos require a Quicktime plugin. If they don't work for you, try upgrading your Quicktime plugin.

Student Worksheets

These are short PDF files you can use to review a section. Each file contains about two pages of review questions, plus the solutions in later pages.

PowerPoint Presentations

These PowerPoint slides summarize the main points of each section. They are probably meant to be used by the instructor to summarize a section, but the students could also use them for review.

Excel Manual

For each section, these handouts describe how to use Excel to solve the problems in this section. For doing the Excel assignments in our class you are probably better off studying our own Excel tutorials, but you may find these handouts useful as well.

Graphing Calculator Instructions

For each section, these handouts describe how to use TI graphing calculators to solve the problems in this section. At least that is the theory.
