Continuing an Expression
You can use
Ans
as the first entry in the next expression without entering the value again or
pressing
y Z
. On a blank line on the home screen, enter the function. The TI-84 Plus pastes
the variable name
Ans
to the screen, then the function.
Storing Answers
To store an answer, store
Ans
to a variable before you evaluate another expression.
Calculate the area of a circle of radius 5 meters. Next, calculate the volume of a cylinder of radius
5 meters and height 3.3 meters, and then store the result in the variable V.
TI-84 Plus Menus
Using a TI-84 Plus Menu
You can access most TI-84 Plus operations using menus. When you press a key or key
combination to display a menu, one or more menu names appear on the top line of the screen.
•
The menu name on the left side of the top line is highlighted. Up to seven items in that menu
are displayed, beginning with item 1, which also is highlighted.
•
A number or letter identifies each menu item’s place in the menu. The order is 1 through 9,
then 0, then A, B, C, and so on. The
LIST NAMES
,
PRGM EXEC
, and
PRGM EDIT
menus only
label items 1 through 9 and 0.
•
When the menu continues beyond the displayed items, a down arrow (
$
) replaces the colon
next to the last displayed item.
•
When a menu item ends in an ellipsis (
...
), the item displays a secondary menu or editor when
you select it.
•
When an asterisk (
ä
) appears to the left of a menu item, that item is stored in user data archive
(Chapter 18).
