# Starting *Mathematica*

*Mathematica* is available on all computers in all Carleton computer labs. For example, you can use it in the computer labs CMC 301 and CMC 201, which are open until 1 AM. We will use version 6 of the software.

## Installing *Mathematica* On Your Own Computer

If you're satisfied using *Mathematica* on a lab computer, then skip this section. On the other hand, if you have your own computer (running Mac OS X, Linux, or Windows) then you can install *Mathematica* on it and work from there. The official instructions are on this page.
The instructions involve several steps, any one of which might hit a snag. Remember that you can always resort to a lab computer, or talk to the SCIC for help with installation.

## Starting A Tutorial

Once you're sitting at a computer that has *Mathematica* installed, here's what you do. Log in, open a web browser such as Firefox or Internet Explorer, and go to the class web page. There you will see a file called "Tutorial 1: Introduction To *Mathematica*". The actual name of the file is "111.tutorial1.nb". The ".nb" at the end stands for "notebook" — it indicates that the file is a *Mathematica* file.

If you click on this file in your web browser, it will probably look like garbage, because your browser doesn't know the *Mathematica* language. Instead, save the file to your computer, by right-clicking on it (on Mac OS X, Linux, or Windows) or control-clicking on it (on Mac OS X with a one-button mouse). (If you are using Safari on Mac OS X, then the file may have been saved with a ".txt" appended to the end of its name. If so, rename the file to get rid of the ".txt".)

You should be able to open the notebook file just by double-clicking it. If this doesn't work, then open the *Mathematica* program itself, go to the File menu, and open the file from there. At that point, you should be viewing the notebook file. Follow the instructions there. I strongly encourage you to work with a friend.

## Getting Help

For help with installing the software on your own computer, talk to SCIC.

For help with using the software, go to CMC 301; a schedule of friendly helpers is posted in that room. I am also happy to help you in office hours.
