You might have it on the wrong mode. try going to mode, and see if the func selection is highlighted. If the SEQ is highlighted, it will show u, n, and min stuff. plot 1, plot2, and plot3 will show at all times anyway. there is nothing wrong with having them. You can always try reseting the calc. just remember to archive data

I was plotting graphs of quadratic functions and all of a sudden i had error message: INVALID DIM. What do I do?


If you were graphing equations in the y= screen, chances are that you have Plot 1 or one of the other plots on. You can tell if this is the case if you have a black box over plot 1, plot 2 or plot 3 in the y= screen. To turn of the plot with the black box over it, arrow up and over if needed to highlight this black box. Press enter and you will turn the plots off and should be able to graph.

Another solution is is press the 2nd key, then the + key, then the 7 key, then the 1 key & the 2 key. This clears the RAM and resets the calculator to the original factory defaults.

Remember.....2nd....+....7.....1....2

Hope this helps/

When I entered my data in L2 because in L1 I don't know what happened is not on the screen then I press STAT and select CALC, then select 1- Var Stats and press enter I should be able to see the mean,...


When you select 1-Var Stats, specify L2. If you don't specify a list, the calculator will assume L1.

You can recreate L1 by pressing
2ND [{] 1 STO 2ND [L1]

{ is on the ( key.
L1 is on the 1 key.

When I hit the "GRAPH"


Hi emmabatting,

One of the statistical plot's may be on while your trying to graph other functions. You can go to the y= editor / STAT editor and, turn them all OFF.

1). Press [CLEAR] at the Home screen
2). Press [2nd][Y=] Open's the (STAT PLOT) editor screen.
3). Press [4:PlotsOFF]
4). The PlotsOff Command should now display at the Home screen.
5). Press [ENTER] , Now the plots should be off.

If you still have this error even after you turned off the plot you may have a list that is a invalid dimension. List dimensions can only be between 1 and 999. A matrix can only be between 1 and 99. Or your trying to invert a matrix that isn't square.

If you want to examine the list, lists or matrix that is given you trouble just [2nd] [list]. Then stroll and, select the one you want to look at by pressing, [ENTER]. You'll have to press, [ENTER] again and, the list or, matrix should display at the Home screen. The lists your looking for are probably the ones used to make plots. You can do the same looking for matrices, just use the [2nd] [MATRX], instead of [2nd] [list]. At the Home when you get to them your looking for the ones that are not square, like 2 by2 or 4 by 4 etc.


But, if you do find a invalid list or, matrix to delete press, [2nd] [MEM] [2] and then, [4] for lists or, [5] for matrices. This will display all the lists or, matrices to delete. You can go through them and, see if one or, a few of them are the ones you want to delete. To delete a list or, matrix just stroll to the list you want to delete with the little dot marker to the left of the list or, matrix and, press [Del]. If the list or, matrix is archived you will have to unarchive it first. To unarchive a list or matrix just hit the [ENTER] key and, a asterisk will disappear and, now press [Del] key to delete it.


f you can't find the list that is causing you problem you can clear all the lists. To clear all the lists first clear the Home screen by pressing [Clear] at the home screen. Next, press [2nd] [MEM][4] and the ClrAllLists command should display at the Home screen. Next, press [ENTER] and this should set all lists dimensions to 0.

To fix it so you that don't have problems like these, users should group their variables and, lists when they can. And use the SetUpEditor command when make lists. Just little things solve a lot of head aches later on.

Hi, I can edit my table information in my calculator but am not able to graph from it and when i go to table it shows nothing.. what do i do?


Hi,
From what I understand you want to draw statistical graphs (scatter plot, box plot, etc.) If you do not see anything it may be due to the fact that the statistical plots are turned off.

Type in the data in lists L1 and L2, etc. Press [2nd][QUIT]

Press [2nd][Y=] (STAT PLOT] . Select [4:PlotsOff] [ENTER] .
Screen displays Done

Press [2nd][Y=] (STAT PLOT] . Select [1:Plot1 Off].
  1. The configuration screen for Plot1 opens with the cursor blinking ON.
  2. Press [ENTER] to turn Plot1 ON.
  3. Use Down Arrow to move cursor to second line Type:
  4. Select the type of statistical plot. Use the right arrow to move highlight on one of the 6 types.
  5. Select the type:scatter, Xline, histogram, box plot, and press [ENTER] to validate the choisce.
  6. Use down arrow to select the Xlist: use [2nd][1] to choose L1, etc. and press [ENTER]
  7. Select the Y-List (L2) and validate by pressing [ENTER]
  8. Select the data-point mark.
  9. Press [GRAPH].
If you do not see the graph or if it is not well centred, press [ZOOM][9:ZoomStat] to restrict the screen to the data entered.

Hope it helps.
Thank you for rating the solution.

Cannot graph invalid dim error


This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.

If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.

Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.

Having trouble with my TI-83 plus


Hello,
Some old junk is in memory. Reset the memory to defaults and everything will be fine. It is a good practice to clear memory before a new calculation.
To reset memory
Press [2nd][MEM][7:Reset][1:All ram][2:Reset] [EMTER] . Clear screen and enter the functions you want to graph.
Hope it helps.

When i grath, there is message " invalid dim"


I think you are saying that when you graph, you get the message "invalid dim"

If you are trying to graph from the y= screen it may me that you have one of the plots on. If this is the case, look at the top of the y= screen. If plot 1, plot 2 or plot 3 has darkened box around it, the plot is on and you need to turn it off. Move your cursor on top of the one that is highlighted and press enter. You should now have the plot turned off and should be able to graph from the y= screen.

Another way to do this is to press 2nd key, plus key and then 7, and then 1 and then 2. This will reset your ram.

Hope this helps
