Casio FX-9750GII - SOFTWARE VERSION 2-00 Manuel utilisateur

Selecting the RUN Qicon 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 uappears above the ukey, selecting u

will offer more on-screen choices.

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 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 xkey is a toggle key that will change answers or

entered numbers back and forth from decimal to fraction

form.

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

press the yellow Lkey, then Okey.

Thezkey is used to obtain a fraction bar. To obtain a

mixed number, press zafter inputting the whole number.

The lkey executes operations. When data is entered,

the lbutton must be pressed to store the data.

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: and press lto store; to draw your function(s), select u.

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

y-inequalities) by selecting the corresponding TYPE button and then press the $to begin

inputting information.

When the TYPE of graph is changed, it only effects 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 Icon Menu system, input the following:



• 32fs-5f-3l

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

made to the viewing window by selecting V-Win e.

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

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

2. q(Root):

Note: To display the next root, simply press $.

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.

4. r(y-intercept):

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

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

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

TABLE

The section is an overview of the TABLE Icon. To select this icon, you may highlight it and press

lor press 5.

The initial screen allows immediate input of functions that are set equal to 0.To change the type

of expression to be entered, press e(TYPE) and select w(r=) for polar coordinates, e(Parm)

for parametric functions or r(CONV) to convert a previously entered function to an inequality.

1. To see a table for the function -4, highlight Y1: and input the following:

• 2z3f-4lu

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 dor q(FORM) to return to the initial screen and then select

y(SET).

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

press lto 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 custom

make tables.

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

to see a plot graph for the function you entered.

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).

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.

STATISTICS

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, you may highlight it and

press lor press 2.

The initial List Editor Screen 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.

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



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).

3. The initial default graph is a scatter-plot. To change the type of graph you would like to use,

press q(GRPH), then u(SET), Nto Graph Type:, for this set of data, we will make a

histogram, press u, and then qfor histogram.

4. Press dto return to your list of data, select q(GPH1) and then lto see your graph.

5. The following screenshots show one-variable calculations that can be obtained by

pressing q.

6. To delete this set of data, press duntil you return to the initial List Editor screen. Select u

for more options, arrow up until List 1 is highlighted, select r(Del-A), then q.

7. For paired variable data, use the following:

Enter List 1 rst, and then $to begin entering List 2. The cursor will automatically move to the
