Question about Texas Instruments TI-84 Plus Calculator

1 Answer

I've had a problem with my calculator. I don't seem to be able to view two equations at the same time. The "=" sign can only be highlighted on one equation in the "Y=" menu and thus only showing one equation at a time. This has happened to me before but I can't remember how I fixed it. I would also like to know how I did it so as to avoid doing this in the future.

OK,
There is an application called TRANSFRM which does transformation graphing (dynamic graphing). You must have used it previously or loaded it in memory.
Anyway, you must unload it.

  1. Press the [APPS] button.
  2. Scroll along the list of Applications to reach th TRANSFRM app.
  3. Highlight it and press [ENTER]
  4. A new screen appears inviting you to select CONTINUE or UNINSTALL.
  5. Select the UNINSTALL option and press ENTER.

My ti-84 is only graphing one linear equation in the y equal when i put two equations in it only show one


The following should help you draw several graphs.
When you enter a function you should press [ENTER] to validate. At the same time, the cursor moves to the next line. Verify that the = sign on the equation already entered is still highlighted.
If for some reason the = sign of an equation is no longer highlighted, use arrow keys to move cursor on the = sign and press [ENTER].

If only one = sign remains highlighted and all others are not, then in all probability the application Transfrm has been executed before and is still lingering in RAM. When in RAM, it takes over the graphing capabilities of the native OS. This prevents you from drawing more than one graph.You must unload it from memory.
  1. Press the [APPS] key.
  2. Scroll down to the line that shows Transfrm.
  3. Highlight it and press [ENTER].
  4. In following screen you are invited to Uninstall or continue.
  5. Press the number to the left of Uninstall. Validate if need be.
  6. Return to the Y= editor to type in functions to graph.

TI 84 plus calculator refuses to graph more than one function


Hello,
Please, read the following, even if you already know some of its contents.
  1. Once you enter an equation, the corresponding equal sign is highlighted by default.
  2. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted.
  3. If one is not highlighted, move the cursor on it and press ENTER.
  4. If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
  5. Command PlotsOff echoes on main screen.
  6. Press [ENTER], screen displays Done.
  7. Restart the graphing procedure.
  8. If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You should make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.
