Chapter 1
The Layout of Your Calculator
1.1 Functions Keys
Immediately beneath your calculator’s screen is the following:
These buttons, through , are your function keys. As with regular computers, function
keys all you access to additional features of the different applications you will use. How these are
used in the various applications will be explained in the appropriate sections of the handbook.
1.2 Blue 2nd and Green Diamond
At the bottom left of your calculator, you have the following:
The two buttons and are some of the most important buttons on your calculator.
Almost everything on your calculator is color-coded. To be able to use items or commands that
are blue or green, you must first press the corresponding button: or .
Find the button under .
Above , you have ”@” in blue and ”GRAPH” in green.
If you wanted to use the ”@” command, you would need to first press and then .
If you wanted to use the ”GRAPH” command, you would press and then .

CHAPTER 1. THE LAYOUT OF YOUR CALCULATOR
1.3 Arrow Keys
At the top right of your calculator, you have the following arrow keys:
These will allow you to move up, down, left, or right in graphs, menus, etc.
1.4 Delete and Clear
The button, located on the bottom of the keyboard and to the right of the spacebar, will delete
one space to the left of the cursor.
The button, located to the right of the screen, will clear an the entire line, function, or other
entry that you have highlighted.
1.5 Other Important Buttons
The button acts as your ”shift” button when using any of the letter keys.
The button will act like ”esc” button on a computer. It will exit out of a menu without
saving any changes or choosing any options.
The button will cancel an operation that is in progress: it will stop graphing mid-graph,
stop calculating mid-calculation, etc.

Chapter 2
The Most Basic Basics
2.1 Turning the Calculator On and Off
To turn on your calculator, press located in the lower left corner.
To turn off your calculator, press and then since ”OFF” is above in blue.
Note: Your calculator will turn itself off after a few minutes of inactivity to save power.
2.2 Adjusting the Screen Contrast
To make the screen darker, hold down and press .
To make the screen lighter, hold down and press .
2.3 The App Screen
When you turn your calculator on, you’ll have a screen that looks something like this:
This is the App Screen. From this screen, you can access the Flash applications that you have
on your calculator. You can scroll up or down with the up/down arrow keys to see the other
applications that came preinstalled or that you have downloaded. To return to the App Screen at
any time, use the calculator’s ”QUIT” function. To do so, press followed by .

CHAPTER 2. THE MOST BASIC BASICS
2.4 The Home Screen
The Home Screen that is highlighted in the picture in section 2.3 is where you will do all of the
calculations that you normally think of doing on a calculator, such as adding, subtracting, etc. To
get to the Home screen either:
a. press while ”Home” is highlighted in the App Screen, or
b. press the , since ”CALC HOME” is in green above .
The Home Screen looks like this:
2.5 Pretty Print
One of the nicest things about the TI-89 calculator is the fact that it uses Pretty Print. Pretty print
is the option to display symbolic mathematics in the format that you would normally use when
writing mathematics. On most other calculators, x4−7x2+ 1 would look like ”x∧4−7x∧2+1.”
On the TI-89 Titanium, x4−7x2+ 1 will look like ”x4−7x2+ 1.”
2.6 The Catalog
The calculator has a limited amount of space on the keypad and cannot have a button for every
operation or command that it can carry out. All of the preprogrammed commands are stored in
the calculators catalog. Find the word ”CATALOG” above the button in blue. To access the
catalog, press . This will allow you to see an alphabetical list of all the commands the
calculator has. To make use of any command, you can scroll up or down with the up/down arrow
keys to move the triangle next to the command that you want to use. Once the triangle is pointing
at the command, press and the command will be brought to the application you were using.
You can also jump to any letter by pressing the key that corresponds to the appropriate letter.
Example:
You want to get to the rand( command in the catalog, but you’re currently at abs(. Press and
you will jump to the beginning of the Rs in the catalog. Then use the up/down arrows to scroll
down to rand(.

Chapter 3
The Settings
3.1 The MODE Button
Before you do anything else, you want to make sure the settings on the calculator are what you
will want for most of the mathematics courses you’ll take. Keep in mind you might use different
settings in certain classes, but your instructor will inform you when these settings need to be
changed.
Press , located under to the right of the screen, to access the settings.
There are 3 pages of settings and you can use , , and to view each page. Within
a page, use the arrows to scroll up or down between the options. The following are the settings I
use on my calculator, for the three respective pages. I would recommend that you use the same
settings for most classes. Again, your instructor will indicate when you need to vary from these
settings for your class.
Some options are grayed out, as they are not options you can change.

CHAPTER 3. THE SETTINGS
3.2 Changing a Setting
Press to view the first page of settings.
If your calculator is brand new, your ”Display Digits” option is probably set to ”FLOAT6.”
You want to change that from ”FLOAT6” to ”FLOAT.” To do so, scroll down with the up/down
arrows to the ”Display Digits” setting. Press the right arrow to see the other options available for
the ”Display Digits.” Use the up/down arrows to scroll up to ”FLOAT.” Once you have FLOAT
highlighted, press once to make the change and go back to the MODE window.
Repeat the same process for all other settings you want to change.
IMPORTANT:
To actually save all of the changes you have made, you must press a second time.
Note:
When you press the second time, you will be brought back to the application or screen you
were using prior to pressing .

Chapter 4
Performing Calculations
Go to your Home Screen by pressing .
4.1 Clearing the Home Screen
If you have anything in your Home Screen, you’ll want to clear it out now. To do this, access the
Tools menu, . Option 8 is ”Clear Home.” There are two options for using this command.
a. Scroll down with the arrows keys until Clear Home is highlighted and then press .
b. Press to select the 8th command. (This is a handy short cut.)
You can do this anytime you want to clear everything out of the Home Screen.
4.2 Addition, Subtraction, Multiplication, Division
In the Home Screen, you enter your calculations on the bottom line, the Command Line.
Example:
To add 1+1, type . This will appear in the Command Line.
Now press to have the calculator perform the calculation.
What you typed in will appear on the left and the result will appear on the right.
