Error in graph

Hi

I must have done something wrong in the graph function, because now I can´t draw any graphs. I only get the message 'ERROR: window variables domain' when I try.

Help?

Regards

I have the same error. Helping my 16 year old graph a log function. I went to the Texas Instruments web site, typed in "windows variables domain" in the support area and they will walk you through correcting the issue. Eric

When i am graphing and I enter- Y1=Sin(theta) it does not graph it and says syntax error


When drawing function graphs of type Y1=, the name of the independent variable should be X
For polar graphs r=.., the independent variable is theta, while for parametric graphs it is T
To enter the default independent variable, press the key marked [X,Theta, T] . It will type in the correct name.

Want to graph simple functions , like y = x and get error message:" undefined variable".


From the alpha keyboard type in NewProb and press ENTER.
This will clear the contents of all the one-letter variables a-z.
Open the Y= editor and type in an expression for the function to draw.
You do not have to enter a multiplication sign between a numerical factor preceding the variable x and x. If a factor is a letter you must explicitly use the multiplication sign.

I am using a casio graphing calculator and I am trying to graph a parametric function. I put the mode on Param and I inserted xt and yt and i press draw. It draw but then stops and gives me an arugment...


The argument error must have something to do with the parametric functions you are drawing. I do not think anybody would know where to look unless you give us the functions.
As to the range of the T-variable, you can set it by pressing [SHIFT][F3] to open the (V-Window) configuration screen. It starts showing Xmin, Xmax. etc. To get to the T range, use down arrow (about 7 times).

When I try to graph, I get ERR:INVALID DIM I tried going to PlotsOff and I still can not graph


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:

If you got the message while trying to draw a graph
  1. Press [2nd][Y=] (STAT PLOT)
  2. Choose option [4:PlotsOff][ENTER]. Screen displays Done
If message popped up while doing something else that involves lists or matrices, the length of lists may be different, or the dimensions of matrices may not be compatible.

To Clear the lists:
  1. Press [2nd][0] (CATALOG)
  2. Press [PGRM] (C) to jump to first command that starts with c.
  3. Use arrow to scroll down to ClrAllLists, select it [ENTER]
  4. Calculator displays Done
  5. Start the new problem.
To reset the Ram press [2nd][+] (MEM) [7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the Ram Cleared message.

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.

I am getting ERR:ARCHIVE 1:QUITE when I try to


I tried all possible situations where one would get an error ERR: ARCHIVED 1:QUIT 2:GOTO in relation to graphing, and I was unable to do so. Thus I cannot explain your error (in relation to graphing). I conclude that the error is unrelated to the graph.

As a general rule, one you get message ... 1:Quit, 2:GOTO press 2 and you will be shown the location where the offending symbol is.

Anyway, to graph functions, always deactivate the statistical plots
  1. Press [2nd][Y=] to access (STATPLOT) then press [4:PlotsOff]
  2. Command PlostOff echoes on main screen.
  3. Press [ENTER], calculator answers Done.
  4. Open the [Y=] editor to enter your function and
  5. Press [GRAPH].
  6. If you do not see any graph,
  • press [ZOOM][6:ZStandard] or
  • adjust the window dimensions by
  • pressing [Zoom] and
  • setting the Xmin,Xmax,Ymin,Ymax values
  • making sure that Xmin is less than Xmax, and Ymin is less than Ymax.

Won't graph two functions


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
  1. Press [2nd][Y=] to open the (STAT PLOT) menu.
  2. Select [4:PlotsOff] and
  3. Press [ENTER].
  4. Calculator displays Done
  5. Restart your graphs.
  6. Adjust the window dimensions if necessary or use the ZOOM function to have all graphs displayed.

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.

  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. To Uninstall it, do as for the Transfm and select the option that will unload it from memory.

How do u get rid of the ShadeRes in your window setting?


Well, that depends.
The real question is: What are you trying to graph?
If you want to graph function y= f(x), then why are you using the Inequalz application, which draws inequations. The ShadeRes(olution) is a system variable needed by the Inequalz application. You can use the default 3 value or change the value to 4, 5, 6, 7, 8.

When Inequalz runs it takes over the graphing functionalities and impose some changes in the calculator configuration, and one of those changes is the appearance of the ShadeRes variable in the Window configuration screen. Also, once the Inequalz App is launched, it remains in memory until you kick it out of Ram, or clear the RAM

My hunch is that you should not be running Inequalz, so I will show you how to unload it of memory so that you can draw your "regular" graphs.

UNLOADING INEQUALZ
  1. Press the [APPS] key
  2. The screen INEQUAL RUNNING is displayed with the following selections
  • 1:Continue
  • 2:Quit Inequal
  • 3:About
You press [2:Quit Inequal] to unload the Application from the memory.
Return to your regular graphing and a Window configuration screen without the ShadeRes variable.

TO SUM UP
If you are drawing inequations with Inequalz, you cannot get rid of the ShadeRes variable. You can only give it another acceptable value.
If you are drawing "regular" function graphs, unload Inequalz from memory.

I cannot plot graph in my Ti 89 graphing calculator


That means one (or more) of the variables you have in your function is not defined. Check to make sure you didn't misspell any variable name. Also, check to make sure you didn't run two variable names together. "ab" is the variable ab, not a times b.
