Hello,

Is it possible to create a table containing (x, y) coordinates in the spreadsheet directly from a function graph in the drawing window? Similar to the basicaction 2ND TABLE on a TI-84 calculator (see attachment)

Kind regards,

Jan

You have 2 ways to get local infos about a function:

- In the spreadsheet, create a column for x values, say starting from cell A2, then, if your function is f, type in cell B2

=f(A2)

and drag down the cell B2 (see attached file)

- You can see (and adjust) a table of values related to your function using the Function Inspector tool.

The Function Inspector tool is located in the Angle toolbox (click the Angle icon in the toolbar to open it)

Or create a sequence of value for x, then a sequence for the correspondent values of f(x) and place the 2 sequences in a tebleTexte.
