k Folder Name Rules

The following are the rules that apply to folder names. Folder names can be up to 8 bytes long. The following characters are allowed in a folder name. Upper-case and lower-case unaccented characters (character codes 65 to 90, 97 to 122) Upper-case and lower-case accented characters (character codes 257 to 416, 513 to 672) Subscript characters (character codes 480 to 491, 496 to 512, 737 to 746, 752 to 766) Numbers (character codes 48 to 57) Underscore (character code 95) Folder names are case-sensitive. For example, each of the following is treated as a different folder name: abc, Abc, aBc, ABC. A reserved word (system variable names, built-in function names, command names, etc.) cannot be used as a folder name. A number, subscript characters or the underscore (_) cannot be used as the first character of a folder name.
Creating and Using Variables
This section explains how to create a new variable (general variable), and provides a simple sample calculation that illustrates how to use a variable.

k Variable Name Rules

The rules for naming variables are identical to those that cover folder names. For more information, see Folder Name Rules above.
1-7-6 Variables and Folders
k Single-character Variable Precautions
Your ClassPad supports the use of single-character variables, which are variables whose names consist of a single character like a or x. Some ClassPad keys (x, y, Z keypad keys, math (mth) soft keyboard X, Y, Z, [ keys, V key set keys, etc.) are dedicated single-character variable name input keys. You cannot use such a key to input a variable name that has more than one character. For example, pressing the keypad keys x and y in succession is interpreted by the ClassPad as the multiplication expression x y, and not as the characters xy. In order to input a variable name made up of two or more characters, use the alphabet (abc) keyboard. For more information, see Using Single-character Variables on page 1-6-12.
k Creating a New Variable
The most common way to create a new variable is assigning a value or expression to the applicable variable name. Use the variable assignment key (W ) to assign data to a variable.

Function: Solves one equation with respect to a variable, and then replaces the same variable in another expression with the obtained result. Syntax: eliminate (Eq/Ineq/List-1, variable, Eq-2 [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To transform y = 2x + 3 to x =, and substitute the result into 2x + 3y = 5 Menu Item: [Action][Equation/Inequality][eliminate]

u getRight

Function: Extracts the right-side elements of an equation or inequality. Syntax: getRight (Eq/Ineq/List [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To extract the right side elements of y = 2x2 + 3x + 5 Menu Item: [Action][Equation/Inequality][getRight]
2-7-42 Using the Action Menu

u getLeft

Function: Extracts the left-side elements of an equation or inequality. Syntax: getLeft (Eq/Ineq/List [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To extract the left side elements of y = 2x2 + 3x + 5 Menu Item: [Action][Equation/Inequality][getLeft]

u absExpand

Function: Divides an absolute value expression into formulas without absolute value. Syntax: absExpand (Eq/Ineq [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To remove the absolute value from |2x 3| = 9 Menu Item: [Action][Equation/Inequality][absExpand]

u andConnect

Function: Combines two equations or inequalities into a single expression. Syntax: andConnect (Eq/Ineq-1, Eq/Ineq-2 [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To rewrite x > 1 and x < 3 into a single inequality Menu Item: [Action][Equation/Inequality][andConnect]
Function: Returns the result of the logical AND of two expressions. Syntax: Exp/Eq/Ineq/List-1 and Exp/Eq/Ineq/List-2 Ineq (inequality) includes the (not equal to) relational operator. Example: To obtain the result of the logical AND of x2 > 1 and x < 0 Menu Item: [Action] [Equation/Inequality] [and]
2-7-43 Using the Action Menu
Function: Returns the result of the logical OR of two expressions. Syntax: Exp/Eq/Ineq/List-1 or Exp/Eq/Ineq/List-2 Ineq (inequality) includes the (not equal to) relational operator. Example: To obtain the result of the logical OR of x = 3 or x > 2 Menu Item: [Action] [Equation/Inequality] [or]
Function: Returns the logical exclusive OR of two expressions. Syntax: Exp/Eq/Ineq/List-1 xor Exp/Eq/Ineq/List-2 Ineq (inequality) includes the (not equal to) relational operator. Example: To obtain the logical exclusive OR of x < 2 xor x < 3 Menu Item: [Action] [Equation/Inequality] [xor]
Function: Returns the logical NOT of an expression. Syntax: not (Exp/Eq/Ineq/List [ ) ] Ineq (inequality) includes the (not equal to) relational operator. Example: To obtain the logical NOT of x = 1 Menu Item: [Action][Equation/Inequality][not]

The above operation is possible only when List (list1 through list6 or a list variable created by you) is selected for the Basic Format dialog box [Table Variable] item. Note that Table Input is the default, so you need to change the [Table Variable] setting in order to generate a table using list values.
3-4-4 Using Table & Graph
k Table Generation Precautions
Table generation is performed using the currently selected function that is of the current function type selected on the Graph Editor window toolbar.

Current function type

Though the selected current function type is y= in the above screenshot, there is no y= type function selected on the Graph Editor window. Tapping # to generate a table when the above condition exists causes the error message No Functions Selected to appear. An inequality cannot be used to generate a table.
Editing Number Table Values
Changing an x-value in the number table automatically calculates and displays the corresponding y-value. Example: To change the x-value in line 3 of the number table from 1 to 2.5 To generate a table, see To generate a number table by specifying a range of values for x using the Table Input dialog box on page 3-4-2.
(1) Tap the cell in line 3 of column x of the number table to select it.
(2) Perform the key operation: z2.5. Pressing z causes the Enter Value dialog box to appear with a minus sign () in the [x-value] input box. Continue with the rest of the key operation to input the required value, and then tap [OK]. This changes the value in the selected cell to the one you input.
The y-value is updated automatically in accordance with the new x-value.
3-4-5 Using Table & Graph
An error message appears and the number table contents are not changed if you enter an illegal value for x (such as 6 0). The data in a Y column (Y1, Y2, etc.) of a table cannot be modified.
Deleting, Inserting, and Adding Number Table Lines
You can use the following procedures to delete, insert, and add number table lines.
u To delete a number table line (1) Tap the x-value of the line you want to delete.
This line will be deleted.
(2) Tap [T-Fact] and then [Delete].
u To insert a number table line (1) Tap the x-value of the line below the location where
you want to insert a line.

k Generating a Summary Table Using Automatically Set x-Values
With this method, the summary table is generated using a range of values from to.
(1) On the Basic Format dialog box, select View Window for the [Summary Table] setting, and specify the value you want for [Cell Width Pattern]. This example uses a [Cell Width Pattern] setting of 4 Cells. To open the Basic Format dialog box, tap O, [Settings], [Setup], and then [Basic Format]. For additional details about Basic Format settings, see 14-3 Setup Menu Settings. (2) Input the function y = x3 3x on the Graph Editor window. Generation of summary tables is supported for y= type functions only. Clear the check boxes of all other functions on the Graph Editor window, if necessary. Select the check box next to y = x3 3x and press E. If the check boxes of more than one y= type functions are selected, the one with the lowest line number (y1, y2, y3, etc.) is used for number table generation. (3) Tap 6 to display the View Window dialog box.
3-4-11 Using Table & Graph
(4) Tap [Memory] and then [Undefined]. This causes all settings on the View Window dialog box to change to Undefined.
(5) Tap the [OK] button to close the View Window dialog box. (6) Tap 4. This starts summary table generation, and displays the result on the Table window. Note that generation of a summary table can take a bit of time.
You can scroll the window to view all of the contents of the table.
3-4-12 Using Table & Graph
Tapping $ here graphs the function using the View Window settings automatically configured for summary table generation.
A monotone increasing function or other special function may not be solvable by the ClassPads internal summary table calculation. If this happens, use the procedure under Generating a Summary Table by Specifying All of the Values for x (page 3-4-14) to calculate the elements of the summary table. In addition to View Window parameters, you can also select previously stored list data to specify the range of a summary table. On the Basic Format dialog box (displayed using the [Setup] menu), select the [Cell] tab, click the Summary Table down arrow button, and then select the name of the list you want to use on the menu that appears. If you draw a graph or generate a summary table while Undefined is specified for View Window parameters, the ClassPad calculates appropriate parameters and configures View Window settings accordingly.
k Generating a Summary Table Using View Window
With this method, the summary table is generated using the range you define for the View Window xmin and xmax parameters.
(1) On the Basic Format dialog box, select View Window for the [Summary Table] setting, and specify the value you want for [Cell Width Pattern]. This example uses a [Cell Width Pattern] setting of 4 Cells. For details about Basic Format settings, see 14-3 Setup Menu Settings. (2) Input the function y = x3 3x on the Graph Editor window. Generation of summary tables is supported for y= type functions only. Clear the check boxes of all other functions on the Graph Editor window, if necessary. Select the check box next to y = x3 3x and press E. If the check boxes of more than one y= type functions are selected, the one with the lowest line number (y1, y2, y3, etc.) is used for number table generation. (3) Tap 6 to display the View Window dialog box.

You can also use drag and drop to input an expression displayed on the Main application window into the 3D Graph Editor window. To do this, perform the same steps as those for the Graph & Table application. For more information, see Quick Graphing of an Expression Using Drag and Drop on page 3-3-9.

5-3-1 Drawing a 3D Graph

5-3 Drawing a 3D Graph
This section explains how to draw a 3D graph, as well as how to change the angle of a graph and how to rotate a graph.
Configuring 3D Graph View Window Parameters
3D Graph View Window parameters let you specify the maximum and minimum values for the x-, y- and z-axis. You can also specify the number of lines you would like for drawing the grid. For the xgrid enter the number of lines you would like drawn within the interval from xmin to xmax. For example, if xmin = 3, xmax = 3 and xgrid= 15, 15 almost vertical lines will be used to display your graph. The ygrid lines will be almost horizontal. After drawing a 3D graph, pressing the = key cycles the 3D Graph [Axes] setting (page 14-3-6) in the following sequence: Off On Box Off, and so on. Before drawing a graph, be sure to first configure View Window parameters as required to ensure proper display of the graph.

11-7-1 Presentation File Transfer Precautions
11-7 Presentation File Transfer Precautions
Note the following important precautions when transferring a presentation file to another ClassPad unit or to a computer. A presentation file is actually a kind of user folder (called a presentation folder) that contains the images that make up the presentation. Every time you create a presentation the Presentation application also generates files for managing it, and stores the files in a folder named Presystm. Whenever you transfer a presentation to another ClassPad unit or a computer, be sure to include both its presentation folder and the Presystm folder. The presentation will not be able to play correctly on the destination device if you do not transfer the proper folders correctly.

Caution

Transferring a Presystm folder from one ClassPad unit to another causes the Presystm folder on the receiving unit to be replaced by the received Presystm folder. This effectively deletes all of the presentation files currently in the memory of the receiving unit. If you do not want to lose your Presentation data, be sure to back the contents of your ClassPad memory before receiving a presentation folder or Presystm folder from another source.

Learn more about cell referencing on the next page.
13-4-6 Editing Cell Contents
Inputting a Cell Reference
A cell reference is a symbol that references the value of one cell for use by another cell. If you input =A1 + B1 into cell C2, for example, the Spreadsheet will add the current value of cell A1 to the current value of cell B1, and display the result in cell C2. There are two types of cell references: relative and absolute. It is very important that you understand the difference between relative and absolute cell references. Otherwise, your spreadsheet may not produce the results you expect.
k Relative Cell Reference
A relative cell reference is one that changes according to its location on the spreadsheet. The cell reference =A1 in cell C2, for example, is a reference to the cell located two columns to the left and one cell up from the current cell (C2, in this case). Because of this, if we copy or cut the contents of cell C2 and paste them into cell D12, for example, the cell reference will change automatically to =B11, because B11 is two columns to the left and one cell up from cell D12. Be sure to remember that relative cell references always change dynamically in this way whenever you move them using cut and paste, or drag and drop.
When you cut or copy a relative cell reference from the edit box, it is copied to the clipboard as text and pasted as-is without changing. If =A1 is in cell C2 and you copy =A1 from the edit box and paste it into cell D12, for example, D12 will also be =A1.
k Absolute Cell References
An absolute cell reference is the one that does not change, regardless of where it is located or where it is copied to or moved to. You can make both the row and column of a cell reference absolute, or you can make only the row or only the column of a cell reference absolute, as described below. This cell reference: $A$1 $A1 A$1 Does this: Always refers to column A, row 1 Always refers to column A, but the row changes dynamically when moved, as with a relative cell reference Always refers to row 1, but the column changes dynamically when moved, as with a relative cell reference

Graph Menu

After selecting data on the spreadsheet, use the [Graph] menu to select the type of graph you want to draw. You can also use the [Graph] menu to specify whether to graph data by column or row. The following explains each of the [Graph] menu commands, and shows examples of what happens to the Graph window when you execute a command.
The following examples show the appearance of graph screens after tapping r on the icon panel so the Graph window fills the entire screen. Each command is followed by a button in parentheses to show the graph toolbar button that performs the same action as the command.

u [Graph] - [Pie] ( Z )

When you select a pie chart, only the first series (row or column) of the selected data is used. Tapping any of the sections of a pie graph causes three values to appear at the bottom of the screen: the cell location, a data value for the section, and a percent value that indicates the portion of the total data that the data value represents.

u [Graph] - [Scatter] ( X )
In the case of a scatter graph, the first series (column or row) of selected values is used as the x-values for all plots. The other selected values are used as the y-value for each of the plots. This means if you select four columns of data (like Columns A, B, C, and D), for example, there will be three different plot point types: (A, B), (A, C), and (A, D). Scatter graphs initially have plotted points only. You can add lines by selecting [Lines] on the [View] menu.

u [Graph] - [Row Series]

Selecting this option treats each row as a set of data. The value in each column is plotted as a vertical axis value. The following shows a graph of the same data as the above example, except this time [Row Series] is selected.

u [Graph] - [Column Series]
Selecting this option treats each column as a separate set of data. The value in each row is plotted as a vertical axis value. The following shows a typical clustered column graph while [Column Series] is selected, and the data that produced it.
