Ti 83 black screen problem

i had the same problem. If you hit 2nd down 2nd down 2nd down and keep repeating untill the screen clears it should solve the problem. i tried the other solutions that tried clearing the memory and they didnt do anything but erase the equations i had previously put in it (great). But this should work.

TI-30XS won't show square roots

You've got two different issues here. Square root of 39 IS the exact answer, as the result will be a surd (an irrational number with too many - or potentially infinite decimal places). If you have been asked to round or show your answer to a number of decimal places then you use the answer toggle (the opposing arrows button above enter) to receive an approximation - a rounded answer (6.24 to two d.p. if you were to multiply these together you will see it is close to 39, but not EXACT, because it has been rounded already). You can also press the answer toggle again to see a longer decimal, but again this is rounded and not exact

The buttons on my TI-30X

I had the same issue.
  1. Open up the calculator.
  2. Remove the battery.
  3. Remove the two screws holding the display section down.
  4. Carefully pry the button circuit board up and remove it.
  5. Use an electrical cleaner and lint free cloth to wipe off the button circuit board.
  6. Re-assemble and test.
For me, cleaning off the button circuit board restored all buttons to working order. When it is disassembled, and after cleaning, you could flip the board, display, etc. up and out of the case and test to see if it works as well.

Ti-84 BINOMIAL PDF

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had; Trails: 13 P: 53/100 X Value: L1 (List 1) And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

My TI-84 Plus won't graph two functions at once.

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.

TI-83 Plus ( finding linear regression) gives wrong y-intercept (b=) value sometimes. Please tell me why?

I get the same answer. Is b wrong? When I do it in Excel I get b= -2E+06, which is -1 797 322.99 rounded to the millions, in scientific notation. Let me know if you have any questions. Good luck, Paul
