GRAPHING FUNCTIONS
(1) Table Setting
• To display the table, press . (Note that it is essential to input an equation and set
the table before using this function.)
• Table setting allows you to input data necessary for creating a table.
• Press Ï
to enter the table setting screen. (See the figure below.)
• The cursor pointer is initially located at “Auto”, showing the variable input method.
Auto: Automatically creates a table using the function equation and given TableStart
and TableStep values.
User: Displays a blank table. As you input values for variable columns, table values
are automatically calculated by the function
equation to complete the table. Thus, although
TableStart and TableStep inputs can be made
when selecting User, set values will not be used.
• Press < or > to switch between “Auto” and
“User”.
• TableStart is a start value of the variable in the table, and TableStep is a step value
of the variable. Both are numeric values.
<Example>
To automatically create a table starting from -5 with a step of 1 in the X-Y coordinate
after equations, “Y1 = X”, “Y2 = X
2
”, and “Y3 = -X
2
+ 3” have been input.

* After the table has been displayed, the screen can be
scrolled vertically using ≤ or ≥.
* Even though the cursor is on the top or bottom line of the
table, use of ≥ and ≤ is allowed. In this case, the
table set screen is also changed with correspondence to the
table display.
