*Mathematica* Basics—Lists
### Introduction
*Mathematica* uses lists as an efficient way of expressing many of it own
built-in commands, and also when managing data. Lists are always denoted in
*Mathematica* by their enclosure in braces. e.g. {a,b,c} is a list in
*Mathematica*. The notebook that you're about to start is intended to get
you used to the basics of working with *Mathematica* lists.
#### Evaluating Commands
Remember, as we said in the introduction to the first notebook, in order to
tell *Mathematica* that you want it to actually evaluate what you have
typed, hit the ENTER key over on the extreme right side of your keyboard on the
numeric keypad. Again, don't confuse this with the RETURN key, which merely
starts a new line of text.
You can now switch to an actual *Mathematica* practice notebook by
clicking on the icon on the left. It may take a while to start up! Don't forget to come back
here when you're done! (You can also return here just to reread the instructions.) See you in a few
minutes.
Welcome back! You may be wondering how well you did. Click on the icon on the left to see the answers you should have gotten. (Only the answers are given, so if you don't match our results you need to figure out what you did wrong.)
You're now done with this lab. Next you may go to the Table of Contents for the *Mathematica* Basics Labs, or go to the Table of Contents for all of the Differential Equations
Labs, or simply quit. |
