Introduction
TI InterActive! is a document-creation program with the math
features of a powerful TI graphing handheld. It lets you build
documents that contain not only text and pictures but also
dynamically connected graphing and calculation objects.
What makes a TI InterActive! document different?
What can I do with TI InterActive!?
The interactive math objects in a TI InterActive! document set it
apart from the documents that you create with other Windows®
applications. Your documents can use data from the Internet,
TI data-collection tools, and supported TI graphing handhelds—
TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-89, TI-92, TI-92
Plus, Voyage™ 200.

Starting TI InterActive!
To install TI InterActive! on your computer:
1. Close all open programs. Open programs can slow the
installation process.
2. Insert the TI InterActive! CD in your CD-ROM drive.
3. If the installer does not start automatically, click the
Windows Start button, and then click Run. Type
D:\setup.exe,
and then press Enter on the computer
keyboard. (Substitute the letter of your CD-ROM drive if it is
not D.)
4. Follow the installation instructions that are displayed. When
the installer has completed, it returns you to the Windows
desktop. You might need to reboot the computer before using
TI InterActive!.
After completing the installation, it’s a good idea to start
TI InterActive! and test the connections that you plan to use.
¦
There will be a new icon on your desktop. Double-click it.
Depending on your machine and its configuration, it may take
a few seconds for the application to open. TI InterActive! starts
with the cursor at the top of a blank document.

areas of your network or server. If you are using a dial-up
connection, check to ensure that your modem is working
properly.
Testing your e-mail connection
Many Web sites contain a button or block of text that you can
click to send an e-mail message to support personnel. Perform
this test to make sure your e-mail program is registered as your
e-mail client.
1. Click the Windows Start button, and then click Run.
2. In the text box, type

Exercise 1: Performing Calculations in a Document
You perform many calculations in TI InterActive! documents by
inserting a Math Box object. Data that you store and functions
that you define in a Math Box can be used by subsequent
objects, such as graphs, tables, and other Math Boxes.
This exercise shows you how to:
¦
Enter and format ordinary text.
¦
Access and use the Math Palette.
¦
Use a Math Box object to perform simple calculations in a
document.
¦
Enter math and other special functions symbols.
¦
Save a TI InterActive! document.

Entering and formatting text
Evaluating a math expression
Entering text in a TI InterActive! document is similar to entering
text in most text editors and word processors. For this exercise,
you enter a page title and then change the font and point size.
1. Type
Homework
on the first line of your document.
2. Highlight the typed text and select a different font type and
size from the font dialog box (Format 8 Font).
3. Place the cursor at the end of the line and press the Enter key
on the computer keyboard to start a new line.
Suppose you want to evaluate an expression such as

and
display both the expression and its result within the document.
1. Click the Math Box button
on the TI InterActive! toolbar.
An empty Math Box is inserted, accompanied by the TI Math
Palette.
The Math Box looks like

You can, however, change the form of any Math Box result by
setting the Computation Mode of the box.
1. Click anywhere in the existing Math Box to select it. A solid
border appears around the Math Box to show that it is
selected.

Saving a TI InterActive! document
TI InterActive! uses a .tii extension to identify its documents.
1. On the TI InterActive! toolbar, click the Save button
.
Because you have not yet saved this document,
TI InterActive! displays the Save As dialog box.
2. If necessary, navigate to the folder where you want to store
the document.
3. In the File name box, type a name (such as
first report
) for
the document.
4. Click Save.
Note:
You can also export a document to other formats. Choose
Export from the File menu. The options are Html Web Page, Word
Compatible, Rich Text Format, and Plain Text.

Exercise 2: Storing Values as Variables
You can store a value as a named variable and then use the name
to refer to that value in subsequent Math Boxes and graphs. When
TI InterActive! evaluates an expression containing the name, it
substitutes the value stored under that name.
This exercise shows you how to:
¦
Define a variable and assign a value to it.
¦
Display a variable’s value in a document.
¦
Remove a variable.
¦
Perform symbolic calculations.
¦
Reposition TI InterActive! objects in a document.
¦
Reset all variables.
