Introduction

The TI-89 Titanium graphing calculator

This guidebook provides information about a powerful, advanced

graphing calculator available from Texas Instruments: the TI-89 Titanium.

Your TI-89 Titanium comes equipped with a variety of preinstalled

software applications (Apps) that have features relevant to many

different subjects and curriculums.

Using Flash read-only memory (ROM) for the TI-89 Titanium (4 megabytes

[MB] available), you can install additional Apps and increase the

capabilities of your calculator. Installing Apps and operating system (OS)

upgrades is like installing software on a computer. All you need is

TI Connect™ software and a TI Connectivity Cable.

The TI-89 Titanium graphical user interface (GUI) and configurable Apps

desktop make it easy to organize Apps into categories that you create.

Extend the reach of your TI-89 Titanium with accessories, such as the

Calculator-Based Laboratory™ (CBL 2™) systems, Calculator-Based

Ranger™ (CBR™) system, TI-Presenter™ video adapter, and

TI ViewScreenoverhead panel.

The CBL 2 and CBR systems offer static and real-world data collection.

Use the TI-Presenter video adapter to connect the TI-89 Titanium to video

display/recording devices, such as TVs, VCRs, video cameras, and

computer projectors. The TI ViewScreen overhead panel lets you project

an enlarged image of the TI-89 Titanium display so an entire class can

view it.

How to use this guidebook

We’ve added conventions to make it easier for you to get the most out of

this guidebook.

• Key symbols appear throughout the guidebook.

• Many keys can perform more than one function. To use secondary

functions, which are printed above the keys, you must first press 2,

j, or ¹. These extra functions are printed within brackets in this

guidebook.

For example, a procedure might include this key sequence used to

display a menu of special characters:

Press 2¿. (Press and release the 2key, then press the ¿

key, which is the second function of the «key.)

vi Introduction

• Key commands that require you to press and hold two keys at the

same time are indicated by the phrase press and hold. For example,

the instruction to darken the display contrast is:

Press and hold 8and tap «.

• Your graphing calculator uses menus to access many operations.

Menu options often can be selected using one of two methods. For

example,

Press „9:Trig

means that you can choose the Trig option first by pressing „and

then either pressing the 9key or pressing Das many times as

required to select Trig, and then pressing ¸.

The chapters in this guidebook include:

Getting Started – Offers students and educators in all curriculums a

quick overview of the basic operations of the TI-89 Titanium.

Previews – A set of short examples that include step-by-step procedures,

actual keystrokes, and sample displays.

Activities – A set of longer examples that shows how to solve, analyze,

and visualize actual mathematical problems.

Connectivity – How to link your graphing calculator to another

calculator or to a computer using either the USB or the I/O port, with

details about how to transmit variables and applications, and how to

upgrade the operating system.

Memory and Variable Management – How to manage variables

stored in your graphing calculator’s memory and in the data archive, a

protected area of memory separate from RAM (random access memory).

Technical Reference – Includes the syntax and action of each function

and instruction included in the operating system, an alphabetical listing

of operations, error messages, and other reference information.

The remainder of the product information is available in electronic form.

This comprehensive set of electronic chapters is included on the CD-ROM

that came with your TI-89 Titanium. This same information is also

available online as a free download at:

education.ti.com/guides

Getting Started 1

Getting Started

Initial start-up

Installing the AAA Batteries

The TI-89 Titanium uses four AAA alkaline batteries and a backup silver

oxide battery (SR44SW or 303). The backup batteries are already

installed, and the AAA batteries are provided with the product.

1. Remove the battery cover from the back of the calculator.

2. Unwrap the four AAA batteries provided with your product and

insert them in the battery compartment. Arrange the batteries

according to the polarity (+ and -) diagram in the battery

compartment.

3. Replace the battery cover on the calculator. The cover should snap

into place.

Turning on your TI-89 Titanium for the first time

After installing the batteries included with the calculator, press ´. The

Apps desktop appears.

2 Getting Started

Note: If your calculator initializes the preinstalled Apps, a progress bar

will appear with the message “Installation in progress . . . Do

not interrupt!” instead of the Apps desktop. To avoid losing Apps, do

not remove the batteries during initialization. (You can re-install Apps

from either the Product CD-ROM or education.ti.com.)

Adjusting the contrast

The Apps desktop

The Apps desktop is the starting point for operating your TI-89 Titanium.

Your installed Apps appear on the Apps desktop as icons organized in

categories for easy access. From the Apps desktop, you can:

• Open Apps.

• Select and edit categories of Apps.

• View all of the Apps installed on your calculator.

• View the full name of the highlighted App.

• View and edit the time and date.

• Check status line information.

• View split-screen mode information.

Getting Started 3

ÊView full name of highlighted App.

ËView time and date.

ÌPress ¸to open highlighted App.

ÍScroll down to view additional Apps.

ÎCheck status line information.

ÏEdit categories.

To return to the Apps desktop at any time, press O. The last category

selected appears with the last open App highlighted.

Turning off the calculator

Press 2®. The next time you turn on the calculator, the Apps

desktop appears with the same settings and memory contents retained.

(If you turned off the Apps desktop, the calculator Home screen appears.)

You can use either of the following keys to turn off the TI-89 Titanium.

Note: ® is the second function of the ´ key.

The calculator’s Automatic Power Down™ (APD™) feature prolongs

battery life by turning the calculator off automatically following several

minutes of inactivity. When you turn on the calculator after APD:

• The display, cursor, and any error conditions are exactly the same as

before APD.

• All settings and memory contents are retained.

Press: Description

2 ® (press 2

and then press ®)

Settings and memory contents are retained

by the Constant Memory™ feature.

• You cannot, however, use 2 ® if an

error message is displayed.

• When you turn the TI-89 Titanium on

again, it displays either the Home screen

or the Apps desktop (regardless of the

last application you used).

¥ ® (press ¥

and then press ®)

Similar to 2 ® except:

• You can use ¥ ® if an error message is

displayed.

• When you turn the TI-89 Titanium on

again, it will be exactly as you left it.

4 Getting Started

Note: APD does not function when a calculation or program is in

progress, unless a pause is specified in the calculation or program.

TI-89 Titanium keys

ÊFunction keys (ƒ– Š) open toolbar menus, access Apps, and edit

categories of Apps.

ËCursor keys (A, B, C, D) move the cursor.

ÌNumeric keypad performs math and scientific functions.

ÍModifier keys (2, 8, 7) add features by increasing the number of

key commands.
