(not applicable to other areas). NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. [. . . ] You can then press a cursor key or tap the graph controller arrows to move the pointer to the location you want, and read the coordinates that appear on the display. To start the trace operation and display the pointer, make the 3D Graph window active, and then tap =, or tap [Analysis] and then [Trace]. · Each time you press the cursor key or tap a graph controller arrow, the pointer moves the distance specified by the [grid] value on the 3D View Window dialog box. · Inputting a value while a trace operation is being performed displays a dialog box for inputting an x- and y-coordinate. Inputting values for each of the coordinates on this dialog box causes the pointer to jump to the corresponding location when you tap [OK]. To cancel the trace operation, tap on the icon panel. Tip · The initial default setting for the coordinate display is rectangular coordinates (Rectangular). Tapping O, [Settings], [Setup], and then [3D Format] displays the 3D Format dialog box, which you can use to select polar coordinates (Polar) or to hide coordinate values entirely. · For details about the settings you can configure on the 3D Format dialog box, see "3D Format Dialog Box" on page 14-3-6. Inserting Text into a 3D Graph Window You can insert text into a 3D Graph window and delete it as required. For more information, see "To write text on the Graph window" on page 3-6-2, and "To clear figures inserted using the Sketch menu" on page 3-6-5. 20050501 5-5-2 Other 3D Graph Application Functions Calculating a z-value for Particular x- and y-values Use the following procedure to calculate a z-value for given x- and y-values on the displayed graph. u ClassPad Operation (1) Draw the graph and make the 3D Graph window active. · This displays a dialog box for specifying the x- and y-values. (3) Enter values for x and y, and then tap [OK]. · This displays the x-, y-, and z-coordinate values on the 3D Graph window. The message "z-Cal" on the 3D Graph window indicates a z-Cal operation is in progress. · Inputting a value while you have a graph displayed, will display a dialog box for specifying an x- and y-value. You can use the dialog box to specify other x- and y-values. · To cancel the z-Cal operation, tap on the icon panel. 20050501 Chapter 6 Using the Sequence Application The Sequence application provides you with the tools you need to work with explicit sequences and recursive type sequences. 6-1 6-2 6-3 6-4 Sequence Application Overview Inputting an Expression in the Sequence Application Recursive and Explicit Form of a Sequence Using LinkTrace 20050501 6-1-1 Sequence Application Overview 6-1 Sequence Application Overview This section describes the configuration of the Sequence application window, and provides basic information about its menus and commands. Starting up the Sequence Application Use the following procedure to start up the Sequence application. u ClassPad Operation On the application menu, tap H. This starts the Sequence application and displays the Sequence Editor window and the Table window. Sequence Application Window When you start up the Sequence application, two windows appear on the display screen: the Sequence Editor window and Table window. Tabs: Select either [Recursive] or [Explicit]. Sequence Editor window (a) (b) Table window: For creation and display of tables. (a) Title: Shows the equation used in the calculations. The title is not displayed when an item in column n is selected. (b) Column names Tap to copy the area selected in the message box to the clipboard. Message box Shows the value of the currently selected table cell. Tap to paste the clipboard contents at the current cursor position in the message box. 20050501 6-1-2 Sequence Application Overview Sequence Application Menus and Buttons This section explains the operations you can perform using the menus and buttons of the Sequence application's windows. k Sequence Editor Window Menus and Buttons O Menu To do this: Configure settings for all applications Display the soft keyboard Display the Sequence Editor window Display the Table window Display the Graph window Display the Sequence RUN window Start up the Main application Close the currently active window Select this O menu item: Settings Keyboard Sequence Editor Table Graph Sequence RUN Main Close Edit Menu To do this: Cut the currently selected object and place it onto the clipboard* Select this Edit menu item: Cut Copy Paste Select All Clear All Copy the currently selected object and place it onto the clipboard* Paste the current clipboard contents onto the screen Select all objects on the screen* Clear the active window * These commands are available only for line edit operation when the Graph or Table window is active.
