When I try to graph a funtion, such as y=x^2, this error message pops up and says "Window Variable Domian" Because of this error, I cannot graph any funtins on my TI-89. Could someone please help me out? Thank you very much!
Have you tried to change the window????
there is a second function over one of the f buttons which has window....
most likely you put the negative number for the max and the positive number for the min x or y value!
if all else fails....
there is a button on the back which will just clear all your settings...
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Your function is not correctly defined. If graph is function y=f(x), variable must be x; if graph is polar, variable must be theta, and if graph is parametric, variable must be t. This does not cover all possible cases. Check the graph type and the definition of the function.
An ERR: MEMORY is given when there is not enough memory to
perform the instruction or function. To increase available memory by
deleting the contents of any variable (real or complex number, list,
matrix, Y= variable, program, Apps, AppVars, picture, graph database, or
string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu. • Press 2: Mem Mgmt/Del. • Select a variable or data that needs to be deleted and press [ENTER]. •
Use the arrow keys to move the cursor next to the item, and then press
[DEL]. The variable or data should now be deleted from the memory. When
deleting programs or Apps, a message asking for confirmation will
appear. Select 2:Yes to continue. To leave any variable screen without
deleting anything, press [2nd] [MODE].
The variable t is reserved for parametric graphs. If you want to use functions of the form y=, then the default variable is x. You can enter it by pressing the X,T,Theta key. Besides, what you name a variable is purely a matter of style. Call it what you may, it will not change the shape of the graph. The full name of a variable is dummy variable, meaning that the symbol you use is irrelevant. You do have to conform to the idiosyncrasies of your calculator, otherwise it will complain and send you error messages.
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
Press [2nd][Y=] to access (STATPLOT) then press [4:PlotsOff]
Command PlostOff echoes on main screen.
Press [ENTER], calculator answers Done.
Open the [Y=] editor to enter your function and
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.
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.
I have a manual in another language than English, so I do no know exactly or remotely what procedure you refer to, but I have recreated an instance where one gets the error you talk about. I give you the picts.
When I enter [Diamond][Graph] I get the following message.
The graph independent variable is x by default, yet I entered cos(f). The calculator is expecting a function of x and I give it a function of some as other entity. Hence the error message. On the command line you cannot change the argument of Y1. It is x by default.
You're probably getting a dimension error trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.
