Question about Casio CFX-9850G Plus Calculator

Hello,

Since you are drawing graphs of functions, the most obvious cause is that the range of values. It is also possible that you are performing an illogical operation like dividing by zero.

Check that the numeric values are in the correct range.

Hope it helps.

What happened when you tried going to PlotsOff. Did you actually execute the command?

If you executed that command and cannot graph then for some reason you are feeding lists or matrices as arguments to the functions you want to draw.

By the way are you drawing STATISTICAL GRAPHS or FUNCTION GRAPHS?

If you are drawing statistical graphs and you executed the PlotsOff command, it is normal you will not be able to graph because PlotsOff turns OFF the statistical graphs.

Here are a few things you can do:

It is most likely that the lists you are using as input data are of unequal lengths: One has fewer elements than the other.

I just created a small data set in two lists of unequal length. I was able to draw the scatter plot, but when I wanted to get a regression curve the error message popped up.

Read the first part of the answer to deactivate the statistical plots. No need to read the rest if you know how to do graphs.

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

Setup Graph type

Entering the functions to draw (assuming you want to draw y= functions)

Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

Drawing the Graphs

ZOOMING

You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

Setup Graph type

- Press [MODE] key.
- In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
- Use the arrows to move cursor to 3rd line to highlight
degree or radian and press [ENTER]. The important thing is that you be
aware of the unit so that you do not get unexpected results.
- On same screen, verify that
**Func**is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list - If it is not, use arrow to highlight Func and press [ENTER] to validate.
- Do not worry if you do not have exactly the same screen
as in the screen picture (We may have different OS Versions)

Entering the functions to draw (assuming you want to draw y= functions)

- Press [Y=] to enter function editor.
- Type in a function
- Press [ENTER] at the end of each function.
- Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
- In the screen capture 4 functions are slated to be
drawn.

Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

- Select the graph style:
The small piece of line to the left of a Y that defines a function is
the style.
- Move cursor on it and press [ENTER] .
- Each [ENTER] (on same line) selects another style.
- On the next screen you have all the styles available on the calculator.
- Do not select the bubble on line 6: It is for
animations. It will not leave a trace at the end of the plot.

Drawing the Graphs

- Press [GRAPH] to see the graphs.
- If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
- Here are the dimensions of the standard window

ZOOMING

You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

A. This is due to a mathematical error such as

- dividing by 0,
- an illogical operation,
- calculations outside the range of a function,
- using the exponential function with the [^] key,
- logarithm of a negative number,
- calculating the factorial of numbers larger that 69,
- what have you.
- Check the expression of the function you are trying to graph.

- Use keys to highlight [GRAPH] and press [EXE].
- Make sure the screen that opens says Graph Func Y= at the top.
- On the Y1= line enter X (use the [X,theta,T] key under the [ALPHA] key.
- Press [F6:Draw].
- You should see a staright line passing through the origin (0,0).

Error messages are important to help solve the problem.

Try the following instructions to draw the function Y=5X+2

but first Reset the calculator by pressing the RESET button on back of calculator. I do not want you to run into problems created by old settings.

Try the following instructions to draw the function Y=5X+2

but first Reset the calculator by pressing the RESET button on back of calculator. I do not want you to run into problems created by old settings.

- 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 type 5 then press the [X, theta,T] key, under the [ALPHA]. On the screen appears 5X, complete your equation by typing [+] 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 (move the center
of the graph. You can pan Up, Down, Left, or Right.
- You can also press [SHIFT][V-Window] to set the window limits.

A) IF YOU GET AN ERROR MESSAGE,

it might be worthwhile to let us know its contents. If you do get a message ( INVALID DIM) you should turn the statistical plots OFF.

To turn statistical plots off

B) IF YOU DO NOT GET AN ERROR MESSAGE

Usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.

The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must Uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

Another potential culprit is the Inequalz App. To Uninstall it, do as for the Transfm and select the option that will unload it from memory.
