PROGRAMMING FUNCTION
<Example>
Set Xmin = –3, Xmax = 10, Xscl = 1, Ymin=–5, Ymax = 5, Yscl = 1 in the WINDOW
screen.
Use Î to input the settings.
Expression Operational sequence
-3 ⇒ Xmin — 3 Î
B®A 1®
10 ⇒ Xmax 10 Î
B®A 2®
1 ⇒ Xscl 1 Î B®A 3®
-5 ⇒ Ymin — 5 Î B®A 4®
5 ⇒ Ymax 5 Î
B®A 5®
1 ⇒ Yscl 1 Î B®A 6®
* Operation to input a function equation (for example, x
2
+ 2) to the graphic equation “Y1” is also
made using Î in the same manner as described above.
“X
2
+ 2” ⇒ Y1:
Ï A 2
+ 2
Ï A 2

A®A 1
<Example>
The following data are included in list L1.
L1: 165, 182.5, 173.8, 166.5, 185.3
A one-variable statistical data calculation was executed based on this data.
After returning to the normal function calculation screen, average values can be viewed
by using the following procedure.
• Press
H ® A 0 2 to display
“ ”
on
the screen.
• Press ® to call out the average value of X as
determined in the previous calculation.
• In this way, the contents of an immediately preceding statistical calculation can be
stored as statistical values.
• These contents remain until the next statistical calculation is executed, even if the
power is turned off.
• The same is true even for regression calculations and verification calculations.
