The lkey executes operations. When data is

entered, the lbutton must be pressed to store the

data.

The zkey is used to obtain a fraction bar. To obtain

a mixed number, press Lz.

The Okey will power the unit on. To turn the unit

off, press LO.

The xkey is a toggle key that will change answers

or entered numbers back and forth from decimal to

standard form.

The dkey operates like the back arrow on a web

browser; it will take you back one screen each time

you select it. The dkey will not take you to the icon

menu.

The pkey displays every mode the calculator has.

To select a mode, you may $B to the desired icon

and press lor press the number or letter in the

lower right hand corner of the icon.

The function keys allow you to access the tab (soft

key) menus that will come up at the bottom of the

screen. When an uappears above the ukey,

selecting uwill offer more on-screen choices.

Selecting the RUN-MATRIX icon will allow you to

perform general computations and arithmetic.

Icon Menu Name Description

RUN-MATRIX This icon menu is used for general computations, including absolute value, logs of any base,

summation, derivatives, integrals, and matricies.

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.

This section is an overview of the RUN-MAT Icon. To select an icon from the icon menu system,

use the !$BN to highlight the desired icon, then press lor press the number/letter in the

lower right corner of the icon. For the RUN menu, press 1to 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 Lpqdfrom the RUN menu.

3. To change the answer to a decimal approximation, press x. xis a toggle key that will switch

entered data or answers from standard form to its decimal approximation and back.

2. To change the answer, 24

71 , to a mixed number, press LxX.

1. When performing general computations, you can press zto enter fractions and mixed

numbers. To solve the problem, input the following:

• z5$8$+Lz2$1$3l

4. To change the displayed number of decimal places, 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.

Note: Every icon’s SET UP menu is accessed in the same manner.

• LpNNNNNNNNNNNq3ldlx

From the RUN menu, many calculations can be performed by selecting i. For example:

hyperbolic, probability/distribution, numeric (including differential and integration), conversion, engi-

neering, complex number and binary, octal, decimal and hexadecimal calculations.

5. To calculate the number of different arrangements of 10 items when choosing 4 at a time, enter

the following from the RUN home screen:

• iue10w4l

6. To calculate -103+ 2 , enter the following from the RUN home screen:

• iewn10^3$+2l

Calculations can be performed with complex numbers and answers can be displayed in a+bi form.

7. To calculate (-3 + 2i ) + 15i; enter the following:

• ie(n3+2q)+15ql

Sigma calculations can also be performed in the RUN menu.

8. To calculate ; enter the following:

• iruea,s-3a,+5$a,$2$6l

This section is an overview of the GRAPH Icon and will highlight some basic features of this mode.

To enter the Graph menu, highlight the icon and press lor press 5.

The initial screen is the function/relation editor. Enter a function in Y1 and press lto solve it. To

draw the function, press u(DRAW).

To quickly change your window, you can utilize the Replay arrows. Specic changes can be made

to the viewing window by selecting e(V-Win).

To analyze features of this graph (roots, maximum and minimums, y-intercepts, intersections,

determine coordinates, and integrals), select y(G-Solv).

Note: When the TYPE of graph is changed, it only affects the current line and entries below

it. Functions already stored are unchanged.

1. To draw the graph of the function y = 2x2 - 5x - 3 from the Graph Editor system, input the

following:

• 2fs-5f-3lu

You can change the type of graph (r = polar coordinates, parametric functions, x =, and

inequalities) by pressing e(TYPE), then selecting the corresponding TYPE button. Press $to

begin inputting.

GRAPH

2. q(Root):

5. q(y-calculation): What is the value of ywhen xis -5?

6. w(x-calculation): What is the value(s) of x when y is 1?

7. e(integral): Determine the integral value from (0, 3) for the function Y1= 2x2 - 5x - 3.

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.

4. r(y-intercept):

Note: The left-most root will always display rst. To display the next root, simply press $.

This section is an overview of the TABLE Icon. To select this icon, highlight it and press lor press

Note: Functions previously entered in Graph will appear in Table.

3. However, you can manually enter a number anywhere in the x-column of the table and press l

to see the corresponding y-value (including fractions, decimals, even π). You can insert and

delete rows in this view by pressing e(ROW). This is a quick way to customize your table.

2. The default setting for tables is: X starts at 1, ends at 5, and increases by increments of 1. You

change this by pressing y(SET). When complete, press d, then u(TABL).

TABLE

1. To see a table for the function , highlight Y1: and input the following:

• z2$3$f-4l

fx-9860GII Quick Start Guide 9

4. From the table view screen, you can press y(G-CON) to see a connected plot linear graph or

u(G-PLT) to see a plot graph for the function you entered.

Note: Moving the cursor to a differential coefcient displays “dy/dx” in the top line, which

indicates differential.

If you manually entered values to the previous table that you still want displayed, you can re-enter

them here, then press lto see the graph of that table.

To generate a differential number table, press Lpto enter the SET UP menu for the TABLE

icon and Nto Derivative, select q(On), then d.

6. For this example, enter YI: 3x2- 2 and Y2: x2. Press u(TABL) to view the differential number

table.

5. To see a split screen of your table and graph, press Lpto enter the SET UP menu for the

TABLE icon. Scroll down to Dual Screen, select q(T + G), d, then u(TABL).

TABLE

fx-9860GII Quick Start Guide

This section is an overview of the STAT Icon; it will highlight just a few of the features for single-

variable data and paired-variable data. To select this icon, highlight it and press lor press 2.

The initial screen is the List Editor Screen that allows input of statistical data and performs

numerous statistical calculations. To input a list of single-variable data, highlight the rst cell

under List 1 and enter each number followed by l.

2. From this screen you can display various statistical graphs depending on whether you have

single or paired-variable data (scatter-plot, line, normal probability, histogram, median box, mean

box, normal distribution, broken line, and regression: linear, quadratic, cubic, quartic, logarithmic,

exponential, power, sinusoidal and logistic).

1. For this example, input this set of data:
