In order to select additional graphs, the Transformation Graphing Application will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family.

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?

The fact that you are asking how to graph makes believe that you solved the problem about 'invalid dimension' . I am glad that worked for you.

This

1. Prepare calculator for graphing
Turn StatPlotsOff to avoid errors:

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

2. 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)

3. 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.

4. 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.

5. 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

6. ZOOMING
You can also press [ZOOM] to adjust.

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

Only graph one function at a time

A) Before drawing function Y1=f(X), R1=F(Theta), (X1=f(T), Y1=f(T))
you should turn the statistical plots OFF.
To turn statistical plots off
1. Press [2nd][Y=] to open the (STAT PLOT) menu.
2. Select [4:PlotsOff] and
3. Press [ENTER].
4. Calculator displays Done
6. Adjust the window dimensions if necessary or use the ZOOM function to have all graphs displayed.
B) If you cannot draw more than one function

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.
1. Press the [Apps] key.
2. Scroll down or up to reach the Transfmapplication.
3. Select it and press [ENTER].
4. If that application was running you will see a new screen that tells you some thing like
• Transfrm App
• 1:Uninstall
• 2:Continue

Press1:Uninstall.
Graphing functionalities will revert to the native OS

Another potential culprit is the Inequalz App. You recognize that Inequalz is runnibg if the [ Y=] editor screen shows tabs at the bottom

To uninstall it, do as for the Transfm and select the option that will unload it from memory.
1. Press [Apps]
2. Select [ : Inequalz]
3. Screen displays Inequal RUNNING
• [1:Continue]
• [2:Quit Inequal]
Press [2:Quit Inequal]
