6 Tables
To create a table of values, an equation must be defined using the y= window.
For our example we will use y1 = x
2
. Make sure that the equation y1 is check
marked. Use the toolbar option labeled # to access the table. The values
of the table will depend on the current table settings. You may access these
settings using the toolbar option 8.
Example 9. Create a table for y1 = x
2
and y2 =
1
/x for −3 ≤ x ≤ 3. We
change the table settings to include x values from −3 to 3.
Note that an error message is created for y2 =
1
/x when x = 0. We also see
that both functions y1 and y2 are equal when x = 1.
