Calculator Notes for the fx-7400G Plus
Note 1A • Setting the Mode
Each mode on your calculator has different settings that you can change.
From the Main Menu, select
RUN
. Press
[SET UP]
to display the screens
at right. The settings shown here are the ones that you will use most often
in this course while in
RUN
mode. Arrow down to see more settings. Other
modes may have different choices on their setup screens. If your calculator
does not display these settings in
RUN
, follow the steps below to change them.
a.
Use the arrow key to highlight the setting you want to change.
b.
Press the function key corresponding to the value you want to use.
c.
When you have selected the settings you want, press
to exit
from the setup screen.
In this class, you will need to change some of these settings during the year.
The following list is a description of the mode settings that you may need
(or want) to change. There are some other settings in some modes that
should not concern you in this course. The list may not mean much to you
now, but your textbook will refer you back to this note several times during
the course. All of these settings do not appear in all modes.
a.
S-Wind
(statistics window) should be set to
Man
in this course.
b.
G-Function
(graph function) gives you the choice to display or not
display the function on the screen with its graph.
c.
F-Type
(function type) refers to the type of function (or relation)
currently active on the calculator.
Y
is the usual setting. The
Parm
(parametric) setting and inequality settings are also used. Press
to see the inequality options.
d.
D-Type
(draw type) refers to the way graphs are drawn.
Con
(connected) means that each calculated point will be connected to
the next.
Plot
means that each calculated point is drawn by itself.
e.
Angle
allows you to choose the type of angle measure. In this course,
you will use only the
Deg
(degree measure). This setting is not
important until you reach the chapter on geometry.
f.
Display
refers to the way in which numbers are written. The options
are
Fix
(fixed),
Sci
(scientific),
Norm
(normal), and
Eng
(English).
Usually the setting should be
Norm. Sci
is used in the chapter on
exponents. After you choose
Sci
, you also decide on the total number
of digits you want displayed. The
Fix
setting is useful in hiding long
decimal answers and will make some numbers clearer. After choosing
Fix
, you choose how many digits appear to the right of the decimal
point. This setting is helpful in applications involving money, for
example, where one wants two decimal points showing. Change this
setting back to
Norm
when you don’t need a special display.
g.
Simplify
allows you to decide whether a fraction is automatically
reduced to its lowest terms
(Auto)
or whether you have to reduce it
yourself
(Man)
. Usually this setting should be on
Auto
, unless you
want to practice reducing fractions.
