Calculator Notes for the TI-83 and TI-83/84 Plus
Note 1A • Setting the Mode
Press
to display a screen like that shown here. The settings highlighted are
the ones that you will use most often in this course. If your calculator does not
display these settings, follow the steps below to change them.
1. Use the arrow keys to highlight the setting you want to choose.
2. Press
to register your selection.
3. When you have selected the settings you want, press
[QUIT]
to exit
from the mode screen.
In this class you will need to change some of these settings during the year. The
comments below may not mean much to you now, but your textbook will refer
you back to this note several times during the course.
a.
NORMAL
and
SCI
entific refer to the way in which numbers are
displayed. Both modes are used in the chapter on exponents. Usually
this setting should be on
NORMAL
mode.
b.
FLOAT
and
0 1 2...
refer to other ways in which numbers are displayed.
FLOAT
mode is useful in hiding long decimal answers and will make
some numbers clearer. It is best to leave this setting on
FLOAT
, except
in applications such as money, where only two decimal places make
more sense. Remember to change this setting back to
FLOAT
when you
are done.
c. In this course you will use only the
DEGREE
mode. This setting is not
important until you reach Chapter 11.
d.
FUNC
tion and
PAR
ametric are two different types of graphing modes.
Most of the work in this course will be in
FUNC
mode.
e.
SEQUENTIAL
and
SIMUL
taneous tell the calculator to graph the
equations one at a time, or to graph all the equations simultaneously.
f. Usually you’ll want your screen set to
FULL.
Occasionally, after you have
been working with a program, you may find that you are left with a
split screen. If this happens, be sure to change this setting back to
FULL
.
The remaining settings in the mode screen are not important in this course. If
you find that your screen looks very strange when you try to do something, it’s
a good idea to look at the mode screen and check to see if any settings have
been changed.
