Quick-Start
Welcome to the world of graphing calculators and the CASIO fx-9750G.
Quick-Start is not a complete tutorial, but it takes you through many of the most common functions, from turning the power on to graphing complex equations. When you’re done, you’ll have mastered the basic operation of the fx-9750G and will be ready to proceed with the rest of this manual to learn the entire spectrum of functions available.
Each step of the examples in Quick-Start is shown graphically to help you follow along quickly and easily. When you need to enter the number 57, for example, we’ve indicated it as follows:
Press fh
Whenever necessary, we’ve included samples of what your screen should look like.
If you find that your screen doesn’t match the sample, you can restart from the beginning by pressing the “All Clear” button o.
SWITCHING POWER ON AND OFF
To switch power on, press o.
OFF
To switch power off, press !o.
AUTO POWER OFF FUNCTION
Note that the unit automatically switches power off if you do not perform any operation for about six minutes (about 60 minutes when a calculation is stopped by an output command (^)).
USING MODES
The fx-9750G makes it easy to perform a wide range of calculations by simply selecting the appropriate mode. Before getting into actual calculations and operation examples, let’s take a look at how to navigate around the modes.
To select the RUN Mode
1. Press mto display the Main Menu.
vi
Quick-Start
2.Use defcto highlight RUN and then press w.
This is the initial screen of the RUN mode, where you can perform manual calculations, and run programs.
BASIC CALCULATIONS
With manual calculations, you input formulas from left to right, just as they are written on paper. With formulas that include mixed arithmetic operators and parentheses, the calculator automatically applies true algebraic logic to calculate the result.
Example: 15 × 3 + 61
1.Press oto clear the calculator.
2.Press bf*d+gbw.
Parentheses Calculations
Example: 15 × (3 + 61)
1. Press bf*(d
+gb)w.
Built-In Functions
The fx-9750G includes a number of built-in scientific functions, including trigonometric and logarithmic functions.
Example: 25 × sin 45˚
Important!
Be sure that you specify Deg (degrees) as the angle unit before you try this example.
vii
Quick-Start
1. Press o.
SET UP
2. Press !mto switch the set up display.
3.Press cccc1(Deg) to specify degrees as the angle unit.
4.Press Jto clear the menu.
5.Press oto clear the unit.
6.Press cf*sefw.
REPLAY FEATURES
With the replay feature, simply press dor eto recall the last calculation that was performed. This recalls the calculation so you can make changes or re-execute it as it is.
Example: To change the calculation in the last example from (25 × sin 45˚) to (25 × sin 55˚)
1. Press dto display the last calculation.
2. Press dtwice to move the cursor under the 4.
3.Press f.
4.Press wto execute the calculation again.
viii
Quick-Start
FRACTION CALCULATIONS
You can use the $key to input fractions into calculations. The symbol “ {” is used to separate the various parts of a fraction.
Example: 1 15/16 + 37/9
1.Press o.
2.Press b$bf$
bg+dh$
jw.
Indicates 6 7/144
Converting a Mixed Fraction to an Improper Fraction
d/c
While a mixed fraction is shown on the display, press !$to convert it to an improper fraction.
d/c
Press !$again to convert back to a mixed fraction.
Converting a Fraction to Its Decimal Equivalent
While a fraction is shown on the display, press Mto convert it to its decimal equivalent. Press Magain to convert back to a fraction.

GRAPH FUNCTIONS
The graphing capabilities of this calculator makes it possible to draw complex graphs using either rectangular coordinates (horizontal axis: x ; vertical axis: y) or polar coordinates (angle: θ ; distance from origin: r).
Example 1: To graph Y = X(X + 1)(X – 2)
1.Press m.
2.Use d, e, f, and cto highlight GRAPH, and then press w.
3.Input the formula.
v(v+b) (v-c)w
6
4. Press 6(DRAW) or wto draw the graph.
Example 2: To determine the roots of Y = X(X + 1)(X – 2)
1. Press !5(G-Solv).

xi
Quick-Start
2.Press 1(ROOT). Press efor other roots.
Example 3: Determine the area bounded by the origin and the X = –1 root obtained for Y = X(X + 1)(X – 2)
1. Press !5(G-Solv).
6
2. Press 6(g).
3
3. Press 3(òdx).
4.Use eto move the pointer to the location where X = –1, and then press w. Next, use eagain to move the pointer to the location where X = 0, and then press w
to input the integration range, which becomes shaded on the display.

Quick-Start
DUAL GRAPH
With this function you can split the display between two areas and display two graphs on the same screen.
Example: To draw the following two graphs and determine the points of intersection
Y1 = X(X + 1)(X – 2)
Y2 = X + 1.2
1.Press !Zcc1(Grph) to specify “Graph” for the Dual Screen setting.
1
2. Press J, and then input the two functions.
v(v+b) (v-c)w
v+b.cw

3. Press 6(DRAW) or wto draw the graphs.
BOX ZOOM
Use the Box Zoom function to specify areas of a graph for enlargement.
1.Press ! 2(Zoom) 1(BOX).
2.Use d, e, f, and cto move the pointer
to one corner of the area you want to specify and then press w.
