When i type anything into Y= the error message INVALID DIM comes up. What do I do to fix this?

I believe that you get the error message not when you type anything in Y= editor, but after you hit the {GRAPH] button. Anyway this is due to the fact that one of your statistical plots are active.

If you got the message while trying to draw a graph (that is your situation)
  1. Press [2nd][Y=] (STAT PLOT)
  2. Choose option [4:PlotsOff][ENTER]. Screen displays Done
If message popped up while doing something else that involves lists or matrices, the length of lists may be different, or the dimensions of matrices may not be compatible.

To Clear the lists:
  1. Press [2nd][0] (CATALOG)
  2. Press [PGRM] (C) to jump to first command that starts with c.
  3. Use arrow to scroll down to ClrAllLists, select it [ENTER]
  4. Calculator displays Done
  5. Start the new problem.
To reset the Ram press [2nd][ ] (MEM) [7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the Ram Cleared message.

When the RAM is cleared, the calculator is reset. The calculator resets itself after a battery change.

ERR: INVALID DIM displayed on graphing calculator

The solution for the problem is simple. When you use the calculator to create statistical graphs, it is configured to accommodate the specificities of the problem. However that configuration remains set after you terminate the problem. So when you try to use the calculator to do other problems it uses the stored configuration parameters, which may be incompatible with the new problem. In particular, list of paired-variables must have the same dimensions: There must be the same number of elements in each list.

To make a long story short, you should make it a habit to reset the Ram every time you want to do a new problem. If for reasons of you own you do not want to reset the Ram, you can prevent this type of errors from occurring. This is how you do it.

  1. Press [2nd][Y=] (STATPLOT)
  2. Choose option [4:PlotsOff][ENTER]. Screen displays Done
  3. Press [2nd][0] (CATALOG)
  4. Press [PGRM] (C) to jump to first command that starts with c.
  5. Use arrow to scroll down to ClrAllLists, select it [ENTER]
  6. Calculator displays Done
  7. Start the new problem
To reset the Ram press [2nd][+] (MEM) [7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the Ram Cleared message.

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

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 graphing says ERR: INVALID DIM 1:Quit

You have two lists that don't agree in length.

Solution 1 (easy)

Press [y=] and look at the top line - one of your Plots is highlighted.
Move the arrow to the highlighted one, press enter to get it un-highlighted.

Solution 2 (permanent)

Press [STAT] - EDIT: [1] to edit your lists. Go to the bottom of the lists and see which one is the longest. Delete (DELETE, not clear) the "extra" entries in the longest list until all lists are the same length.

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.
