uGraphs
As a general rule, graph operations are shown on
facing pages, with actual graph examples on the right
hand page. You can produce the same graph on your
calculator by performing the steps under the Procedure
above the graph.
Look for the type of graph you want on the right hand
page, and then go to the page indicated for that graph.
The steps under “Procedure” always use initial RESET
settings.
The step numbers in the “SET UP” and “Execution” sections on the left hand page
correspond to the “Procedure” step numbers on the right hand page.
Example:
Left hand page Right hand page
3. Draw the graph. 3 5(DRAW)(or w)
u uu u uCommand List
The Program Mode Command List (page 8-7) provides a graphic flowchart of the various
function key menus and shows how to maneuver to the menu of commands you need.
Example: The following operation displays Xfct: [VARS]-[FACT]-[Xfct]
u uu u uPage Contents
Three-part page numbers are centered at the top of
each page. The page number “1-2-3”, for example,
indicates Chapter 1, Section 2, page 3.
u uu u uSupplementary Information
Supplementary information is shown at the bottom of each page in a “ (Notes)” block.
* indicates a note about a term that appears in the same page as the note.
# indicates a note that provides general information about topic covered in the same section
as the note.

Use this mode for arithmetic calculations and function
calculations, and for calculations involving binary, octal,
decimal, and hexadecimal values and matrices.
Use this mode to perform single-variable (standard
deviation) and paired-variable (regression) statistical
calculations, to perform tests, to analyze data and to draw
statistical graphs.
Use this mode to store functions, to generate a numeric
table of different solutions as the values assigned to
variables in a function change, and to draw graphs.
Use this mode to store graph functions and to draw
multiple versions of a graph by changing the values
assigned to the variables in a function.
Use this mode to store recursion formulas, to generate a
numeric table of different solutions as the values assigned
to variables in a function change, and to draw graphs.
Use this mode to draw graphs of implicit functions.
Use this mode to solve linear equations with two through
six unknowns, quadratic equations, and cubic equations.
Use this mode to store programs in th program area and
to run programs.
Use this mode to perform algebraic calculations.
Use this mode for step-by-step solution of expressions.
Use this mode to determine the expression type and
solve mode, and for interactive equation solutions.
Use this mode for step-by-step solution of expressions.
Use this mode to manage data stored in memory.
Use this mode to initialize memory, adjust contrast, and
to make other system settings.

k About the Function Menu
Use the function keys (1 to 6) to access the menus and commands in the menu bar
along the bottom of the display screen. You can tell whether a menu bar item is a menu or a
command by its appearance.
• Command (Example: )
Pressing a function key that corresponds to a menu bar command executes the command.
• Pull-up Menu (Example: )
Pressing a function key that corresponds to a pull-up menu opens the menu.
You can use either of the following two methods to select a command from a pull-up menu.
k About Display Screens
This calculator uses two types of display screens: a text screen and a graphic screen. The
text screen can show 21 columns and 8 lines of characters, with the bottom line used for the
function key menu. The graph screen uses an area that measures 127 (W) × 63 (H) dots.
• Input the key to the left of the command on the pull-up menu.
• Use the f and c cursor keys to move the highlighting to the command you want, and then press w.
The symbol ' to the right of a command indicates that executing the command displays a
submenu.
To cancel the pull-up menu without inputting the command, press i.
Text Screen Graph Screen
The contents of each type of screen are stored in independent memory areas. The contents of each type of screen are stored in independent memory areas.
