CHAPTER 4
(11) Displaying tables (See page 121 for details.)
• A table is a chart of values yielded by a function (Yn)
for values of X.
• There are two methods to create tables. In one
method, the entry of a function automatically produces
a table. In the other method, values are manually
entered for X.
• To produce a table, it is necessary to display the TABLE SET screen.
The TABLE SET screen is used to enter information necessary for a table display,
such as whether to use the automatic table function or to manually input values, and
the start value and table step.
1. Press Ï
≥.
Specifies the automatic table production mode.
2. Press — 4 ®.
Sets “-4” in Table Start.
3. Press 1 ®.
Sets “1” in Table Step.
4. Press
.
Displays a table.
Equations for Y1 and Y2 have been entered; therefore, no
value can be entered for the next column.
• Move the cursor pointer in the left-to-right direction by using < >. While
setting tables, pressing > > > > displays Y4 on the right end of the
display, and the Y1 column disappears. As a result, the screen shows X, Y2, Y3 and
Y4 (only when Y3 and Y4 are in the equation and graphing is valid).
• Move the cursor pointer in the vertical direction by using ≤ ≥. In the above
screen, when ≤ is pressed, “-5” appears in the X column, and “1” disappears.
The screen can be scrolled even outside the display range.
