On a TI-35 plus, the "oct" indicator won't turn off

We have a TI-35 plus calculator and accidentally turned it into "oct" mode. Now we can't turn that off. We've tried using the "2nd" function key as well as the "mode" key. Do you have any suggestions?

SOURCE: ti-84 plus

this might seem weird.... but have you checked the brightness of your calculator? if someone was playing with it and set the brightness to 0 it wont seem like there is anything. if u press second then hold the up arrow key it will make the screen darker. I dont know if this will help you or not but i know some of my friends like to play pranks where they set the brightness really high.

Thats because the OS is corrupt. Follow the manual and reload the OS, try the 2.43 OS

My TI-84 Plus won't let me graph trigonometric functions.


Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?

Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].

If it's not the angular mode, please reply to this post and give an example or two.

Batteries won't work


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

My ti-83 plus won't turn on,

I have a TI-83+. My calculator keeps putting everything in scientific notation. For example, "9" comes up "9E0". I have tried resetting but it still won't stop doing that.


Press MODE. Use the arrow keys to highlight NORMAL on the first line and press ENTER. Press 2ND [QUIT] to exit the mode screen.

Alternatively, you can set any other display mode on that screen.

There's a blank bar that runs horizontal in the middle of my TI-84 plus that's about 16 pixels wide(high?). It's the same color as when the device is turned off. I've tried a memory reset and no results....


SPLIT SCREEN.

It sounds as if you might have split screen mode on. I've got a TI-83 as well as a TI-89 Titanium, both offer a split screen mode. The latter allows for choosing which applications are displayed on each half screen. I am presuming that you may have accidentally put your TI-84 in this mode.

So, if it is a split screen deal then all you have to do is go to the mode screen, find the option for switching from split screen to full screen, and switch it back to full.

I hope that helps. Give us your results!

Adios

How do i turn theta off on the [X,T, theta, n] key on a TI-83 Plus calculator?


That key gives theta when the calculator is set to polar graphing mode. It gives X in the function mode, T in the parametric mode, and n in the sequence mode.

To change the mode, press MODE to bring up the mode screen. Use the arrow keys to move to the fourth line and highlight the desired mode. Press ENTER to make the change, then press 2ND [QUIT] to exit the mode screen.

From TI FAQs:

What troubleshooting can I try if the TI graphing calculator will not turn on?

For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect™ first.
  1. Try a new set of AAA batteries.
  2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
  4. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
  5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

Make sure the battery contacts are clean. I just fixed mine, as it had been sitting for some years and the batteries went bad.

I gently cleaned any "green mold" from the contacts with a light Scotch-Brite pad and some electrical contact spray that I got at a local hardware store.

I tested the batteries with my digital meter to make sure they were 1.5V or more and put everything back together. Works great!

Give it a whirl---this is a nice little calculator. I bought mine in 1990-1991 and it's gotten me through undergraduate and graduate school...
