Your TI-84 Plus displays the ERR:DIM MISMATCH error if you are trying to perform an operation that references one or more lists or matrices whose dimensions do not match.
For example, multiplying L1*L2, where L1={1,2,3,4,5} and L2={1,2} produces an ERR:DIM MISMATCH error because the number of elements in L1 and L2 do not match

That is a piece of cake. just go to the two Lists that you are using for the equation and see if they are the same length.

SOURCE: TI-83 Plus Calculator: what does ERR: DIM MISMATCH mean?...

Imagine you are doing statistical calculations with two list, say L1 and L2 but one list has 10 elements (values) while the other has only 9. The dimension of the lists are different (mismatched) because one is 10 and the other 9.

Another case is if you are manipulating matrices such as adding a3x3 matrix to 3x2 matrix. Both matrices have the same number of rows but different numbers of columns.

There is an APPlication called Inequalz that graphs inequalities. you must have executed it previously and it is still lingering in memory. You must unload it from RAM.
Press the APPS button. find Inequalz in the list of apps highlight it and press ENTER. You will see a screen that display INEQUAL RUNNING. Press 2:Quit Inequal. It will be unloaded from memory.

I cannot get the calculator to graph more than one line. I've tried highlighting teh equals sign and hitting entor to make it dark but it will only highlight one equation at a time.


One of the applications Inequalz or Transfrm is still loaded in memory and it controls the graphing capabilities of the calculator. To restore control to the naative OS, proceed as follows.
Press the APPS button.
Scroll dowwn or Up to find Inequalz.
Select it and press ENTER.
A message is displayed sayin Inequal Running.
Select 2:Quit Inequal.

If the message you get is
APP CONFICT.
or Conflicting Apps
Reset the RAM to kick the applications out of memory

How do i use the "shades" or "Po-I-Trace" menus on the TI-84?


Press APPS. Scroll up or down to reach Inequalz and press ENTER. The inequalz application will know control function graphing. Open the Y= editor to enter at least two inequalities . Use the tabs at the bottom to type in the relational operators. You will have to press [ALPHA] followed by [F1], or [F2], etc

7_30_2011_12_32_29_pm.jpg
Press the GRAPH function key (F5) to draw the graphs. You get the two regions superposed (original shading).

7_30_2011_12_35_32_pm.jpg
Press [ALPHA][F1 or F2] to activate the [SHADES] tab. This open up the following screen.

7_30_2011_12_38_54_pm.jpg
On this screen you can choose the type of shading 1: Intersection of the two regions ( the part of the plane that satisfies both inequalities, 2 the union of the two regions or 3 the original shading (as compared to choice 2). Selecting option 1:intersection gives you the following screen.

If you press the [ALPHA][F5] keys you have the HELP ? screen below.

7_30_2011_12_50_23_pm.jpg
If you press the [ALPHA] [F3] keys you get a Point of Interest (You should consult the manual for the Inequalz application for more details.
7_30_2011_12_52_14_pm.jpg
By pressing the TRACE button (not ALPHA F4) and the left or right arrows you you can follow the graph of one of the functions. You jump to the other functions by pressing the Up or Down arrows.

Im trying to do and inequality problem. however when i go to my apps button and then click on inequalz it sends me to a messege that sais conflicting apps and it gives me 2 options and a code at the end....


Transfrm and Inequalz both perform graphs. However, when you execute one of them it stay in memory and takes over graphing from the native OS. So if Transfrm is in memory and you execute the Inequalz application, you get the message you described..
To do Inequality graphing, press [2:Quit APPS] listed below, and Transfrm will be kicked out of memory.

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
  5. Restart your graphs.
  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.

  2. Select [ : Inequalz]
  3. Screen displays Inequal RUNNING

Changing Y= to Y greater than


Do you want to change from graphing functions to inequalities or the opposite? A complete sentence would help.
I am going to assume that you want to graph y=f(x) functions, but when you opened the Y= editor, you found unusual symbols.
If the is the case, then you must have run the Inequalz Application. It stays in memory and takes over the graphing from the native OS. Inequalz must be unloaded from memory to return control to the native OS.
Here is how to do it.

  1. Press the [APPS] key.
  2. In the list of Apps find Inequalz.
  3. Type the number in the list that corresponds to Inequalz and
  4. press ENTER
  5. The new screen displays INEQUAL RUNNING and 3 choices
  • 1:Continue
  • 2:Quit Inequal
  • About
Press 2:Quit Inequal to unloade the App from memory. Control will revert to the native OS, and you will be able to draw Y= graphs.

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.

It says invalid dim when try to plot and in window it has shaderes=3 or something like that. And also it shows inequalities at the bottom and some ****.


Hi,
You are running the application called Inequalz. It can be used to plot inequality graphs. You must uninstall it (NOT DELETE) to return to the normal calculator configuration.
Press [APPS]. Scroll down to find Inequalz. Highlight its number in the list and press {ENTER]. You will see a screen Inequal Running and
  1. Continue
  2. Quit Inequal
  3. 3:About.
Press [2:Quit ..]
Your calculator will unload it out of memory.
Reset the RAM and restart the graphs.

Hope it helps.
