Header area The table above and the photo on the previous page illustrate just a few of the many features available on the HP 50g Graphing Calcu- lator. These topics, as well as other features of the calculator, are discussed in the following quick start guide. For a complete list of fea- tures of the HP 50g Graphing Calculator, refer to the HP 50g Graphing Calculator User’s Manual, the HP 50g Graphing Calculator...

The 50g is capable of performing operations in both Algebraic and Reverse Polish Notation (RPN) modes. Although Algebraic is the default operating mode, it is highly recommended you take the time to learn RPN, as many of the 50g’s features work more efficiently when performed in RPN.
Manual Conventions This manual makes use of certain conventions with text to differentiate between key presses and on screen display options. • Keyboard keys are represented by CAPITAL letters. he symbols represent the left-shift and right-shift keys, respectively.

4 above before preceding. Now that your 50g is ready to go, let’s look at the screen (see Figure 2). The top section is called the header. The header displays important information about the status of the calculator: RAD XYZ HEX R= 'X' ALG and {HOME}. These groups of letters indicate the calculator is set for radians, Cartesian coordinates, the Hexagesimal number base, real numbers with exact results, 'X' as the default variable, and Algebraic operating mode.
The bottom portion is where the edit, or entry line, and the menu appear. For more information on the keyboard, menus, and the calculator display, see Chapter 1 of the HP 50g Graphing Calculator User’s Manual or the HP 50g Graphing Calculator User’s Guide.
RPN's greatest strength is that it lets you work out problems one small piece at a time. You don't have to type everything into a long equa- tion and worry about using parentheses to set the order of operation. Because the 50g comes from a line of calculators that used RPN exclusively, the calculator is easier to use and functions most effectively in RPN mode.

Figure 4 Upon exiting, you will notice that the left side of the screen has numbers from 1-7 (see Figure 5). Press the 2 key, followed by the key. Press the 3 4 keys, in that order, followed by ENTER. The three numbers appear on different levels of the stack, numbered 1-7.

Figure 8 Figure 9 Figure 10 18. Let's calculate 16/3. However, the numbers are in the wrong order on the stack for this operation. No problem, press the RIGHT cursor key to swap their positions (see Figure 8). Now press and 5.33 (repeating) appears.
The final result, 4.5727… is returned. For more information about RPN, see Chapter 2 of the HP 50g Graphing Calculator User’s Manual or www.hp.com/ calculators. Working in Algebraic Mode from RPN Mode 23.
26. With RPN as the active operating mode, you can still use Algebraic mode at anytime. Press so '' appears on the editline. ³ You can now enter data just as you normally would in Algebraic mode. For example, with '' on the editline, type 2 2 .

29. There are two major types of solvers on the 50g: numeric and symbolic. Let's examine the Numeric Solver first. Press followed by 7(N.SLV). A choose box appears. Press 3 and note how the highlight jumps to the corresponding item. Press 1 to jump back to Solve Equation and press ENTER.

Figure 18 Figure 19 Figure 20 Figure 21 Figure 22 Figure 23 Notice how your solver screen now has fields to enter values for A, B, and C (see Figure 22). Note A is currently highlighted. Type 10 and press ENTER. A now has the value 10, and the highlight moves to B. You can also type simple math problems in an input form.
@-]]!] Figure 24). It is necessary to assign units for all three variables so the 50g knows which units to use during the calculation, as the 50g won’t know which unit to assign to a variable without a unit. Note how the units are preceded by the underscore edit mark in the key sequence above by pressing Now press UP to select C and press the SOLVE menu key.

(see Figure 29). The 50g supports compound units as well, such as m/s. Many units are defined by combinations of other unit types. A well known example is the Newton, a measure of force. Press 1 , the FORCE menu key, followed by the N menu key.
--------------- - 40. The 50g supports many other unit capabilities such as prefixes (giga, kilo, centi, micro, etc.) and is an invaluable tool for physics and engineering problems. Using the built-in unit tools, you can utilize units directly in your calculations and save yourself from time-consuming conversions.

Using the equation library, you can numerically solve, with full unit support, series of related equations quickly by entering a few of the variables. Also included with the 50g is the HP Periodic Table of the Elements. The Periodic Table of the Elements displays a graphical...
on those properties, and calculates molecular weights for chemical formulas. These tools come installed on your calculator, and you are encouraged to explore them after you complete this quick start guide. To access these installed library programs, press APPS and scroll to the bottom of the list using the UP or DOWN cursor keys. If you do not see the Equation Library or The Periodic Table of the Elements in that list, it has been deleted from Port 2 of your calculator.

7, and then press ENTER. Your previous EQ appears, along with A, B ,and C. Notice that even though there is no A in this folder, the 50g searches upwards in memory, discovers an A variable in the directory above, and uses it. This behavior can often surprise new users who get an unexpected answer when using the Computer Algebra System (CAS), because an old X variable is found.
Exact and Approximate modes used during calculations. When using the CAS, be aware of all of the calculator’s current settings by glancing at the header. If you do not verify the settings before calculations, the 50g may not return expected results.
Factoring and Solving 64. Another nice feature about RPN in Exact mode is you can build equations on the stack as you work. Press (x key) (see Figure 56). Notice as you type the equation is built step-by-step in the display. 65.

Replacing the Batteries The HP 50g calculator takes 4 AAA (LR03) batteries as a main power source and one CR2032 lithium battery for memory backup. If the low battery sym- bol appears on the display of the HP 50g calculator, replace the batteries as soon as possible. However, to avoid loss of data, remove the backup battery and main batteries at the same time.
