Hi,
My first guess is that the main batteries and the backup battery are depleted. Change the main batteries first and adjust the screen :

  1. Press [2nd] key and release it.
  2. Press and hold UpArrow to darken screen, or DownArrow to lighten it.
Then replace the backup battery.

Hope it helps.

I can't do simple commands like expand( ), integrade, differentiate,... I know that the command is expand(X^3-1) but the answer i get is always { } with no answer in it thanks for ur help Tom


Hi tomschepers1,

I can see why the expand command doesn't work with the equation your inputting. Even though, expand(x^3-1,x) would work better. The expand command does not expand to a complex form. But, your other functions should have worked. The {} tells me your asking the calculator to do something it can't do or, is to big to do, (to many arguments).

So, you need to use the NewProb command at the Home screen. On the command line at the Home screen press, [CLEAR]. Then press, [2nd][F1][2][ENTER] and, the NewProb command will be entered at the Home screen. If that doesn't enable the functions to work properly, then you need to reset your RAM to default conditions. To reset the RAM to it's defaults press, [2nd][MEM][F1][Right Arrow][2][ENTER].

If you have any question about my solution, please post your comment and, I'll respond quickly.

It has been years since I had to use my TI-83 Plus and I can't remember how to clear the lists


  1. Press [2nd][0] to access the (CATALOG).
  2. While catalog of commands is displayed you can scroll gown to reach ClrAllLists.
  3. Alternatively, you press [PRGM] to jump to first command that starts wit C, then scroll down from there.
  4. Select command and press [ENTER].
  5. The ClrAllList commnad echoes on main screen.
  6. Press ENTER to execute command.
  7. Calculator answers Done.

A simpler way. Press [2nd][MEM][4:ClrAllLists] then press [ENTER]

Another more radical way is to reset the RAM. Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Calculator replies with Ram Cleared. Press [CLEAR] to erase the message.

To clear a single list:

Open the statistics data editor [STAT][EDIT]. Navigate to the list you want to clear. Press the Up arror to move cursor to the heading of the list and press [CLEAR] and validate by pressing ENTER.

Other way:

Press [STAT][4:ClrList]
Command echoes on main screen and you have to enter the name of the list. If it is one of the 6 accessible from the keyboard you press [2nd] [1, 2,3, 4,5, or 6] to enter L1, L2,L3,L4,L5 or L6.

My TI-84 Plus won't graph two functions at once. Only one equal sign highlights. My math teacher doesn't even know what to do and I really need two functions to show on one graph.


Hello,
Turn the satistical plots OFF
Press [2nd][Y=] (STATPLOT). Select or enter 4: to execute the command [PlotsOff] [ENTER]

Clear the lists (statistical lists)
Press [2nd][0] (Catalog]. Press [PGRM] C. The cursor jumps to the first command in catalog that starts with C (The greek letters in names do not matter). Scroll down a bit to reach the command [ClrAllLists]. Select it and press [ENTER].

Try your graphs again.
If you still have problems, just reset the RAM:
Press [2nd][+] (MEM). Press 7 to select [Reset] then [1:All Ram][2:Reset]. Press [Clear] to erase the Ram Cleard message.

Now you should be able to draw the graphs.

Hope it helps.
Thanks for using FixYa.

How do I graph on the T1 83 plus when an invalid


Hello,
You must have done some statistical calculations. This type of calculations activates the statistical plots. The resulting configuration conflicts with the normal graph configuration.
Before drawing function graphs, you must turn off the statplots:
Press [2nd][Y=] to access (STATPLOT)
Press [4:PlotsOff][ENTER][ENTER] Calculator displays Done.

Then you press [2nd][0] to access the (CATALOG) of commands. Then [PGRM] to enter the letter [C]. Cursor jumps to the first command that starts with the letter c (omitting the Greek symbols). From there, scroll a bit to highlight [ClrAllLists] and press [ENTER][ENTER]. After clearing the lists the calculator displays Done.

You should be able to draw your graphs.
If that does not work, just reset the Ram as described below.
Press [2nd][+] to access (MEM)
Press [7:Reset][1:All Ram][2:Reset].
Press [CLEAR] to erase the Ram Cleared message.

Press [Y=] and enter your functions. Press [ENTER] at the end of each function. Make sure each [=] after Y1, Y2, remains highlighted after the cursor moves to some other location.

Hope it helps.

When I try to graph it says "ERR: INVALID DIM". How do I get rid of that, so I may graph my equations?

2. Run the command ClrAllLists to clear the lists. Press [2nd][Catalog] Scroll down till you reach the ClrAllLists command. Highlight and press [ENTER]. Command echoes on main screen, press [ENTER] to execute it. Screen displays Done

3. Make sure you are drawing the right type of graph. To check that press [MODE], scroll down to 4th line to highlight Func and press ENTER, if you are drawing y=f(x) functions. The others are PARametric, POLar, SEQuence.

The above procedures (the first two) are likely to solve your problem. In case that does not work reset the RAM.
