Working with Function Tables

The Lists & Spreadsheet application lets you show a table of function values for any function in the current problem. You can change the settings for the table, delete columns, add values for multiple functions, and edit the expression that defines a function without leaving the Lists & Spreadsheet application.

Switching to a Table

While working in the Lists & Spreadsheet application:

Windows: Press Ctrl+T.

Mac®: Press “+T.

Handheld: Press / T.

The Lists & Spreadsheet application disappears and an empty table is displayed with a list of the functions that are available in the problem.

Note: If you have previously shown a table for a function from the Lists & Spreadsheet application, the table includes that function by default.

Choose the name of the function for which you want to display values.

Values for the function you selected are displayed in the first column of the table.

To move through adjacent cells of the table, press ▲ or ▼. Press Tab to move from the body of the table (cells) to the top two rows (cells for column names and formulas).

To hide the table of values and return to the Lists & Spreadsheet application, repeat Step 1.

Making Changes from a Table

You can change the table of function values using the tools on the Table menu.

▶

To remove a column from the table, click any cell and click Delete Column.

▶

To display the list of functions, click a cell in a column and click Choose. Select a cell in an empty column unless you are replacing values already displayed. Click a function in the list to add its values to the column.

Note: You can also click the drop-down arrow on the top cell of a column to display the list of functions in the problem.

▶

To change the expression that defines a function, click Edit Expression. You can also edit the expression directly on the entry line beneath the table.

Note: When you edit the expression for a function, that function automatically changes in the application used to define the function. For example, if you edit a Graphs & Geometry function in the table, the table values and graph of the function are both updated.

▶

To change the default table settings, choose Edit Table Settings.

The Table dialog box opens. Press Tab to move from field to field and type or select new values for the default table settings:

Table Start: Type the value to use as the first value in the table of values.

Table Step: Type a value for the interval between values.

Independent and Dependent: Click the drop-down arrow to choose Auto or Ask as the method for populating a column with the values of the independent and dependent variables. Auto populates the table starting at the defined table start value and displays an independent and dependent value for each step. Ask lets you select a cell and press Enter to generate a value for a cell.
