u Grafer
Som regel vises grafoperationer på modstående sider,
hvor grafeksemplerne vises på højre side. Du kan
frembringe den samme graf på din lommeregner
ved at udføre de trin, der vises under overskriften
Procedure oven over grafen.
Find den type graf, du ønsker, på højre side, og gå
derefter til den side, der er angivet for den pågældende
graf. Trinnene beskrevet under "Procedure" udføres
altid med de oprindelige RESET indstillinger.
Numrene ved afsnittene "Opsætning" og "Fremgangsmåde" på venstre side
svarer til numrene ved "Procedure" på højre side.
Eksempel:
Venstre side Højre side

u Kommandoliste
Liste over kommandoer i tilstanden PRGM (side 8-7) viser et rutediagram over de
forskellige menuer med funktionstaster og viser, hvordan du kommer frem til den menu
med kommandoer, du skal bruge.
Eksempel: Følgende handling viser Xfct: [VARS]-[FACT]-[Xfct]

u Sidens indhold
De tredelte sidetal er centreret øverst på hver side.
F.eks. angiver sidetallet "1-2-3", at det er kapitel 1,
afsnit 2, side 3.

u Ekstra oplysninger
Ekstra oplysninger vises nederst på hver enkelt side i blokken " Noter".
*
angiver en note om en term, der forekomer på samme side som noten.
# angiver en note, der giver generelle oplysninger om et emne, som behandles i samme
afsnit som noten.

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 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.
SYSTEM Use this mode to initialize memory, adjust contrast, and to
make other system settings.
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 Spreadsheet Mode
commands, you can also perform statistical calculations and
graph statistical data using the same procedures that you use
in the STAT Mode.

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

k How to draw a simple graph (1)
Description
Todraw a graph, simply input the applicable function.
Set Up
1. From the Main Menu, enter the GRAPH Mode.
Execution
2. Input the function you want to graph.
Here you would use the V-Window to specify the range and other parameters of the
graph. See 5-2-1.
3. Draw the graph.
