u Grafer
I allmänhet visas de knapptryckningar som behövs för
att rita en graf på uppslagets vänstra sida, med själva
grafen på den högra sidan. Du kan rita samma graf på
din räknare genom att följa stegen under Procedur
ovanför grafen.
Leta efter den graf du vill rita till höger, och fortsätt till
motsvarande sida för den grafen. Stegen under
”Procedur” förutsätter att räknaren har de inställningar
som gäller efter att du har tryckt på RESET.
Stegen under ”Förberedelser” och ”Exekvering” på den vänstra sidan
motsvarar stegen under ”Procedur” på höger sida.
Exempel:
Vänster sida Höger sida

Icon Mode Name Description
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 perfo rm financial calculation s and to draw
(Financial) cash flow an d 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.
SYSTEM Use this mode to initialize memory, adjust contrast, and to
make other system settings.

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 Spreadsheet Mode
commands, you can also perform statistical calculations and

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 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.
