The Okey will power the unit on.
To turn the unit off, press the yellow
Lkey, then Okey.
The l key executes operations.
When data is entered, the l button
must be pressed to store the data.
The
d
key operates like the back
arrow on a web browser; it will take
you back one screen each time you
select it. The d key will not take
you to the icon menu.
Selecting the RUN icon
will allow you to perform
general computations and
arithmetic.
The pkey displays every mode the
calculator has. To select a mode,
you may $B to the desired icon
and press l or press the number or
letter in the lower right hand corner
of the icon.
The x key is a toggle key that will
change answers or entered numbers
back and fourth from decimal to
fraction form.
The zkey is used to obtain a
fraction bar. To obtain a mixed
number, press zafter inputting
the whole number.
The function keys allow you to
access the tab (soft key) menus that
will come up at the bottom of the
screen. When an appears above
the ukey, selecting uwill offer
more on-screen choices.

BASIC FUNCTIONALITY
The following explains the meaning of each icon on the fx-9860GII main icon menu.
ICON Menu Name Description
RUN This icon menu is used for general computations, including binary, octal,
decimal, and hexadecimal functions and matrices.
STATISTICS
This icon menu is used to perform single-variable (standard deviation) and
paired variable (regression) statistical calculations, to perform tests, to
analyze data and to draw statistical graphs.
eeACTIVITY
eActivity lets you input text, math expressions, and other data in a notebook-
like interface. Use this mode when you want to store text, formulas, or built-in
application data in a le.
rSpreadsheet This icon menu is used for creating spreadsheets.
GRAPH The icon menu is used to draw, store and calculate information of functions.
DYNAMIC
GRAPH
This icon menu is used to draw multiple versions of a graph by changing the
values in a function.
TABLE
This icon menu is used to store functions, to generate a numeric table of
different solutions as the values assigned to variables in a function change,
and to draw graphs.
RECURSION
This icon menu is used to store recursion formulas, to generate a numeric
table of different solutions as the values assigned to the variables in a
function change, and to draw graphs.
CONICS
This icon menu is used to graph parabolas, circles, ellipses, and hyperbolas.
You can input a rectangular or polar coordinate function or a parametric
function for graphing.
EQUATION This icon menu is used to solve linear equations with two through six
unknowns, and high-order equations from 2nd to 6th degree.
PROGRAM This icon menu is used to store programs in the program area and to run
programs.
TIME VALUE
OF MONEY
This icon menu is used to perform nancial calculations and to draw cash ow
and other types of graphs.
Data
Analyzer Link
This icon menu is use to control the optionally available EA-200 Data
Analyzer. For information about this icon menu, download the E-CON2
manual from http://edu.casio.com.
LINK This icon menu is used to transfer memory contents or back-up data to
another unit or PC.
MEMORY This icon menu is used to manage data stored in memory.
SYSTEM This icon menu is used to initialize memory, adjust contrast, reset memory,
and to manage other system settings.
GEOMETRY This mode allows you to draw, analyze and animate geometric objects.

RUN
This section is an overview of the Run Icon. To select an icon from the icon menu system,
use the!$BNto highlight the desired icon, then press lor press the
number/letter in the lower right corner of the icon. For the Run menu, press1to display
the initial screen.
Note: All operations in this handout will utilize the “Math” input mode, which allows
natural input and display of certain functions, just as they appear in a textbook. To make
sure your calculator is in “Math” mode, press Lpqd.
1. When performing general computations, you can press zto enter fractions and
mixed numbers. To solve the problem, 3

4. To change the number of decimal places displayed, enter the set up menu by
pressing Lp. Nto Display, select q(Fix) and enter the desired amount of
decimal places followed by l. For this example, 3 decimal places are used.
LpNNNNNNNNNNNq3ldlx
From the Run menu many calculations can be entered by selecting i. For example:
hyperbolic, probability/distribution, numeric (including differential and integration),
conversion, engineering, complex number and binary, octal, decimal and hexadecimal
calculations.

GRAPH
Various icon (Run, Table, Dynamic, Recursion & Conics) will allow you to graph or analyze
the graphs of given information. This section is an overview of the GRAPH Icon and will
highlight some basic features of this mode.
The initial screen allows immediate input of functions set equal to zero. You may begin
inputting data into Y1: pressing lto store. To draw your function, select u.
You can change the type of graph (r = polar coordinate, parametric functions, x =, and
inequalities) by select the corresponding function button and then press$to begin
inputting.
1. To draw the graph of the function from the Icon Menu system, input
the following:
3x5x2y 2
52fs-5f-3l
To analyze features of this graph (roots, maximum and minimums, y-intercepts,
intersections, determine coordinates, and integrals) select y(G-Solv).
2. q(Root):
Note: The left-most root will always display first. Select$to display the next root.

3. e(Minimum):
Note: As long as the x-value of your vertex is in the viewable domain; you do not need to
see the vertex to calculate the minimum value. However, you can change the viewing
window by selecting e(V-Window)in the graph window. You can also change the
window manually by using!$BN.
4. r(y-intercept):
5. q(y-calculation): What is the value of y when x is 5

?
6. w(x-calculation): What is the value (s) of x when y is 1?
7. e(integral): Determine the integral value at (0,3) for the function .3x5x21Y 2
