Introduction

The HP 39gII Graphing Calculator is an easy to use, yet powerful graphing calculator designed for secondary mathematics education

and beyond. This quick start guide covers basic tasks, such as entering and editing expressions, plotting graphs, and making tables of

values. This guide also serves as an introduction to HP Apps. Finally, advanced topics, like working with lists or matrices, are also intro-

duced. It is highly recommended you refer to the HP 39gII Graphing Calculator User’s Guide on the product CD for more information

about any topic presented in this guide. This manual makes use of certain conventions with text to differentiate between key presses and

on-screen display options:

• Keyboard keys are represented by letters or words with the first letter capitalized representing the keys’ functions, for example, Symb

(Symbolic).

• SHIFT, when followed by the Letters or Words representing the keyboard keys and (Letters or Words), indicates the shifted functions

of the keyboard keys printed at the bottom of the keys, for example, SHIFT Math (Cmds).

• Menu items for menu keys are spelled out in CAPITAL letters, followed by the term, menu key.

• Field names, choose box options, and other on screen text appear in BOLD.

• Numbered keys are represented simply by printed numbers: 1, 5, 123.35, etc.

2. Slide up the battery compartment cover.

3. Insert 4 new AAA (LR03) batteries into the compartment.

batteries as soon as possible. Warning! There is danger of explosion if the battery is incorrectly replaced. Replace only with the same or

equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Do not muti-

late, puncture, or dispose of batteries in fire. The batteries can burst or explode, releasing hazardous chemicals.

The Home View

Press the On key or Home to access the Home view. The HP 39gII Home view is divided into four parts, from top to bottom. There is a

Header at the top, with the name of the HP App you're currently using and whether you are in degree (DEG) or radian (RAD) mode. Next

comes the History of calculations. Below that is the Entry Line. Finally, at the bottom is the Menu for the menu keys. The top row of keys

on the HP 39gII keyboard is labeled F1-F6. These are the context-sensitive menu keys. These keys take their functionality from the list of

functions printed at the bottom of the display, which changes as you use the various views of the calculator. There are six menu keys in

all. See Figure 1 for an illustration of these parts of the Home view.

Figure 1

Take a moment to verify the screen is at a contrast that is comfortable to your eye. To adjust the contrast, press On and hold it, then press

either the + (Plus) or the - (Minus) key repeatedly. Each press of the + or - key increases or decreases the contrast, respectively. To turn

the calculator off, press SHIFT followed by On.

Modes

To change the angle measure, the number format, etc., press SHIFT followed by Home (Modes). Use the cursor keys to scroll through the

fields. Use the CHOOSE or CHK menu keys to adjust your preferences, using the CANCL menu key to ignore a change or the OK menu

key to accept one. Once you have set your preferences on the Home Modes page, press the Home key to return to the Home view.

To calculate , enter the expression then press Enter. The HP 39gII displays the results with

12 digits of accuracy.

Now press the Up cursor key twice to highlight the expression you entered. Note that two

additional menu labels are now displayed: COPY and SHOW. The SHOW command

typesets the expression using standard mathematical notation. This command is useful if you

want to check that the expression you entered - with one or more sets of parentheses - is

exactly what you want. In Modes, toggle the Textbook Display field on to automatically

display all expressions entered in Textbook Format.

Deleting and Clearing

Press the COPY menu key to see the expression pasted into the entry line as shown in the

figure to the right. If you had meant to enter , You can change the current expression by

moving the cursor to the right of the 3, then pressing the Backspace key, then typing 5. Press

On (Cancel) to cancel any entry, or Enter to execute the new calculation. Your last few

entries are automatically copied to the clipboard as well. You can copy a number or

expression into the clipboard and then paste it into another field or to the cursor location.
