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.

kHow to drawa simple graph(1)

Description

To draw 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.

Result Screen

# Pressing A while a graph is on the display will return to the screen in step 2.

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.

uCommand List

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]

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.

Description

 

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

kAbout 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.

kAbout 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.

Supplementary information is shown at the bottom of each page in a “ (Notes)” block.
