QUICK START GUIDE
fx-9750GIII
Selecting the RUN-MATRIX icon will allow you to
perform general computations and arithmetic.
The function keys allow you to access the tab (soft
key) menus that will come up at the bottom of the
screen. When an u appears above the u key,
selecting u will offer more on-screen choices.
The p key 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 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.
The v key is a toggle key that will change answers
or entered numbers back and forth from decimal to
standard form.
The O key will power the unit on. To turn the unit
off, press LO.
The b key is used to obtain a fraction bar. To obtain
a mixed number, press Lb.
The l key executes operations. When data is
entered, the l button must be pressed to store the
data.

GRAPH
DYNAMIC GRAPH This icon menu is used to draw multiple versions of a graph by changing certain values in the function.
TABLE
RECURSION
CONICS
EQUATION
This icon menu is used for general computations, including absolute value, logs of any base, summation,
derivatives, integrals, and matricies.
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.
eActivity allows for the input of 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 file.
This icon menu is used to quickly draw, store and calculate information of functions. Can graph polar,
parametric, x=, and inequality graphs on the same screen.
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.
This icon menu is used to store recursive formulas, to generate a numeric table of different solutions as the
values assigned to the variables in a function change, and to draw graphs.
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.
This icon menu is used to solve linear equations with two through six unknowns, and higher-order equations
from 2nd to 6th degree.
PROGRAM This icon menu is used to store programs in the program area and to run programs.

RUN-MAT
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 l or press the number/letter in the
lower right corner of the icon. For the RUN menu, press 1 to display the initial screen.
Note: All operations in this handout will utilize the “Math” input/output 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 from the RUN menu. Linear Input & Output allows for single line input and display of
certain functions. Math/Mix mode allows for natural input and single line display of radical functions. This is a
combination of the Math and Linear modes. In Math/Mix, fractions are still displayed as they would appear in a
textbook.
1. When performing general computations, you can press b to enter fractions and mixed
numbers. To solve the problem, input the following:
• b5$8$+Lb2$1$3l
2. To change the answer,
3. To change the answer to a decimal approximation, press v. v is a toggle key that will switch
entered data or answers from standard form to its decimal approximation and back.

4. To change the displayed number of decimal places, enter the SET UP menu by pressing
Lp. N to 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.
• LpNNNNNNNNNNNq3ldlv
From the RUN menu, many calculations can be performed by selecting i. For example:
hyperbolic, probability/distribution, numeric (including differential and integration), conversion, engineering, 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 initial RUN screen:
• iue10w4l
6. To calculate -103 + 2 , enter the following from the initial RUN screen:
• ren10^3$+2l

GRAPH
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 l or press 5.
The initial screen is the function/relation editor. Enter a function in Y1 and press l to store it. To
draw the function, press u(DRAW).
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.
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 screen, input the
following:
• 2fs-5f-3lu
To quickly change your window, you can utilize the arrow buttons. Specic changes can be made to
the viewing window by selecting e(V-Window).
To analyze features of this graph (roots, maximum and minimums, y-intercepts, intersections,
determine coordinates, and integrals), select y(G-Solv).
