Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

This could be a problem with the settings of the calculator... all the rest of the details are in the question i guess... thanks for your help

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

SOURCE: my graphing calculator won't graph anything

Go to your stat plot screen, and select option 4 (PlotsOff), Press Enter, and try to plot a normal graph again

SOURCE: ERR:DIM MISMATCH

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.

Hello,

Some old configuration settings, or old variables are spoiling your fun. Clear the RAM and start again.

Hope it helps.

SOURCE: WHen trying to graph anything, ERR: INVALID DIM

Hello,

The easiest and quickest way to start graphing is to reset the RAM. Press [2nd][MEM][7:Reset][1:All Ram][2:Reset], then [CLEAR] to clear the RAM Cleared Message and go to the main screen.

Hope it helps.

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.

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

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

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

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.

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.

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.

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.

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

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

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.

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

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.

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

Your calculator will unload it out of memory.

Reset the RAM and restart the graphs.

Hope it helps.
