Getting AcquainteduGraphs

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 draw a simple graph (1)

Description

To draw a graph, simply input the applicable function.

Set Up

1. From the Main Menu, enter the GRPH • TBL 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 5-3-1.

3.Draw the graph.

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]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.

kAbout the Function Menu

Use the function keys (1to 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.

• 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. kAbout 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.
