# Problem using graphing on my casio

I can't get my calculator to graph anything. The only thing that it will do is draw straight lines no matter what I put in for the y equation. I have set the v window at 10 and it still doesn't solve anything. What are the solutions??

This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.

### Graphing ellipse

This is not a graphing calculator. Besides, most graphing calculators are able to graph functions, and conics are not functions. You need a utility that graphs conics. The Casio FX-9750G and others have a conics utility. On the TI83/84 Plus you can download an application that draws them.

### How do I graph sinx on my Casio fx-9750GII calculator?

Turn calculator ON
If you see no icons, press Menu
Press 3 (Graph) draw your function. (more on that later).
If the first line of the display show Graph Func : Y= you should be able to draw your function.
If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.
After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.
Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

### How do I graph y=4/5x -1 (where 4/5 is 4 over 5, not 4 divided by 5)

Before trying to graph anything lift the ambiguity from the expression. That is what parentheses are for. Besides, there is no difference between 4 over 5 and 4 divided by 5. They mean the same thing.
Look at the screen capture and see how many possible interpretations you can have for your expression.

Use parentheses to enforce your intention.
4/5X-1 gives the first expression on display.
4/(5X-1) gives the second expression
4/5X^-1 gives the third.

To graph, press the MENU key then use arrows to focuss on GRAPH. Press ENTER/EXE
In the Y= editor type in the intended expression after Y1= and press EXE.
Press DRAW.

### My fx-9750GA PLUS wont graph lines, cicles or paraballas

To draw functions (regular, parametric, polar, sequences) use the application graph: Highloghted on 1st screen capture. The second screen captures shows you the functions y=f(x). enter a legal expression and press F6 Draw. To set TYPE press the key under TYPE.

To draw conics (circles, parabolas, hyperbolas, and ellipses) use the CONiCS applications. (See 3rd screen ). On 4th capture the equation highlight is one for the parabola. y=x^2

Scroll down or up examining the small graphs. They will show you which equation form to choose.
For the circles

### How to use graphing calculator?

The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

1. Most graphing calculators basically function the same way.
2. You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
3. You enter the algebraic form of the function you want to draw.
4. You press a button or menu to GRAPH
5. The graph is drawn.
6. If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
7. Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
8. You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.

### Graphing syntax error

To draw graphs.
1. Turn calculator ON (isn't that obvious?)
2. If you see no icons, press [MENU]
3. Use arrow to move focus on GRAPH and press [EXE]
4. By default, the graph type is Y=
5. Enter your equation on line Y1=, use the [X,theta,T] key to enter the X-variable
6. Press [EXE] when finished entering a function.
7. Enter other functions if you want.
8. When done, press [F6:Draw].
9. If you do not see a big portion of the curve you can press [SHIFT] [F2:Zoom] and select [F5:Auto]
I am enclosing screen captures. The screens you see may not look exactly as on the FX-9750G, but all menu commands you have to execute are accessed by the same key sequences.

This last one is obtained with the Zoom: Auto

### How do you fix an MA error when attempting to graph a function? I have even tried to graph simple functions like (X) or (5) and it still says MA error.

A. This is due to a mathematical error such as
1. dividing by 0,
2. an illogical operation,
3. calculations outside the range of a function,
4. using the exponential function with the [^] key,
5. logarithm of a negative number,
6. calculating the factorial of numbers larger that 69,
7. what have you.
8. Check the expression of the function you are trying to graph.
B. Reset your calculator and start again: Press the button on the back of the calculator; use a starightened paper clip.Draw the line y=XPress Menu.
1. Use keys to highlight [GRAPH] and press [EXE].
2. Make sure the screen that opens says Graph Func Y= at the top.
3. On the Y1= line enter X (use the [X,theta,T] key under the [ALPHA] key.
4. Press [F6:Draw].
5. You should see a staright line passing through the origin (0,0).

### How do I graph an equation such as y= 5x + 2?

Hello,
Turn calculator ON. If you do not see several icons press [MENu].
Use arrow to select the [GRAPH] application and press [EXE].
In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.
Press [EXE] to store function.
If you want to draw other functions, it is time to do so on that screen.
When done press [F6:Draw}.
If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.
You can also press [SHIFT][V-Window] to set the window limits.

Hope it helps.
