Understanding the TI-Nspire™ Tools
This section provides an overview of the tools used when working with TI-Nspire™
documents on a handheld, including variables, catalog, symbols, and math templates.
Creating TI-Nspire™ Variables
Variables can be any portion or attribute of an object or function created within an
application. Examples of attributes that can become variables are the area of a
rectangle, the radius of a circle, the value contained in a spreadsheet cell or the
contents of a column, or a function expression. When you create a variable, it is stored
in memory within the problem. You will find more information about variables in the
chapter titled Using Variables.
Using the Catalog
Use the catalog to access a list of TI-Nspire™ commands and functions, units, symbols
and expression templates. Commands and functions are listed alphabetically.
Commands or functions not beginning with a letter are found at the end of the list (&,
/, +, -, and so on). To open the catalog:
1. From an open document, press k to open the catalog.
2. Press the number key corresponding to the appropriate tab.
For example, press 2 to show a list of math functions.
3. Press 6 until the item you want to insert is highlighted.
A syntax example for the selected item is displayed at the bottom of the screen.
