Mathematica Basics - Lists
Introduction
Mathematica听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听Mathematica听by their enclosure in braces. e.g.听{a,b,c}听is a list in听Mathematica. The notebook that you're about to start is intended to get you used to the basics of working with听Mathematica听濒颈蝉迟蝉.
Evaluating Commands
Remember, as we said in the introduction to the first notebook, in order to tell听Mathematica听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听Mathematica听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听Table of Contents for the听Mathematica听Basics Labs, or go to the听Table of Contents for all of the Differential Equations Labs, or simply quit.
