Graphs
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

The PRGM 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]

S • SHT Use this mode to perform spreadsheet calculations. Each file
(Spreadsheet) contains a 26-column
⋅
999-line spreadsheet. In addition to
the calculator’s built-in commands and S • SHT mode
commands, you can also perform statistical calculations and
graph statistical data using the same procedures that you use
in the
STAT mode.
GRAPH Use this mode to store graph functions and to draw graphs
using the functions.
DYNA Use this mode to store graph functions and to draw multiple
(Dynamic Graph) versions of a graph by changing the values assigned to the
variables in a function.
TABLE 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.
RECUR Use this mode to store recursion formulas, to generate a
(Recursion) numeric table of different solutions as the values assigned to
variables in a function change, and to draw graphs.
CONICS Use this mode to draw graphs of conic sections.
EQUA Use this mode to solve linear equations with two through six
(Equation) unknowns, quadratic equations, and cubic equations.
PRGM Use this mode to store programs in the program area and to
(Program) run programs.
TVM Use this mode to perform financial calculations and to draw
(Financial) cash flow and other types of graphs. to make
LINK Use this mode to transfer memory contents or back-up data
to another unit or PC.
MEMORY Use this mode to manage data stored in memory.

k k k k 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.
• Next Menu
Example:
Selecting displays a menu of hyperbolic functions.
• Command Input
Example:
Selecting inputs the sinh command.
• Direct Command Execution
Example:
Selecting executes the DRAW command.
k k k k k About Display Screens
This calculator uses two types of display screens: a text screen and a graph 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.
Text Screen Graph Screen
The contents of each type of screen are stored in independent memory areas.
Press !6 (G T) to switch between the graph screen and text screen.
