Online Materials

There is a variety of online materials that comes with our textbook. They are all accessible from MyMathLab, but you have to hunt and gather. I have collected all the links in one place. More explanations are at the end of this page.

These links go into Pearson Publishing web sites. Some links only work if you are logged into MyMathLab in a different window, so that your browser has acquired a cookie.

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.

This leads to a tutorial exercise, provided that you are using Internet Explorer on a Windows machine and 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.

Same as the previous item, except that the problem comes from the problem section instead of the tex

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.

The videos cannot be saved to your local machine, but we have the source for all videos (2.09 GB total). They will fit on one DVD, 4 CDs, or a 4 GB flash drive. If you leave out chapters 8 and 9, which we don't cover and which are not even in the ISU textbook edition, they will fit on 3 CDs or a 2 GB flash drive. Contact Fritz Keinert (keinert@iastate.edu, 294-5223) if you want to burn a copy. The textbook representative has given us permission to do that.

Each individual video is a few MB in length. That should work fine as streaming video for individuals, but it is not recommended to have a whole classroom watch videos at the same time, unless they come from a local CD or DVD.

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. At the time of this writing, these links are broken. We are waiting for the publisher to fix that.

For graphing calculator help, use the links at the bottom of the table above. Those do work, and describe several calculators in detail (just not specifically for this course).

Plugins

Everything in the table above, except the tutorial exercises, works in any web browser equipped with the standard plugins (Flash, PDF, Quicktime).

For the tutorial exercises, you need to have the MathXL player installed, which only exists for Internet Explorer on a Windows machine. It is installed in both Math Department computer labs. For your personal machine, the MyMathLab Installation Wizard will walk you through the installation.

The Installation Wizard will attempt to install or upgrade the MathXL player plus plugins for TestGen, Flash, PDF and Quicktime, maybe even more stuff. That may take considerable time and several reboots. You can kill the installation process after the MathXL player has been installed. We don't use TestGen, and your Flash, PDF and Quicktime plugins are likely to be new enough to work. If something doesn't work for you, you can always go back and do the full install process.
