### Changing faceplate on ti-84 i understand it can't be done but has anybody actually tried

Assuming you mean a TI-84 Plus Silver Edition, yes, I have. Simply pry up the tab at the bottom of the keyboard with a thumbnail and work the faceplate off from the bottom. Put the new one starting at the top and work your way down.

### Is it possible to change the faceplate of the TI-84 Plus calculator?

Yes, you can change the faceplate of the TI 84PLUS Silver Edition only, not the TI 84 Plus. Face plates are available for purchase at the TI online store.When you go the online store, select the country, then the calculator model. You will find them under accessories for the TI 84 Plus SE.

### I need to solve 77=9/5c+32 on a ti-84 plus

You don't really need the calculator for this one:

77 = 9/5c + 32
-32 -32

45 = 9/5c
*5 *5

225 = 9c
*1/9 *1/9

therefore:

c = 25

Now to test that value, plug in the c value:

77=9/5(25) + 32
77=45 + 32
77=77 correct so c=25

### When ever i turn on my ti-84, it says waiting..... PLease install operating system now.

Hi biancaaii,

You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix the problem by installing the newest Ti 84 Plus 2.55v. MP OS. operating system.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84 Plus. Hopefully your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work.

If you can't find a calculator to connect to you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS. Be careful, even a power failure during the process of installing the OS will destory your calculator.

Procedure 1 to installing the latest Ti84 Plus 2.55v. MP OS

1). You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.

Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed.

Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install.

Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.

If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.

### Please help me to use my TI - 84 so I can get a radical number when working with larger numbers. the steps I must take and having the TI - 84 set to the right function

I am afraid I do not completely understand what you want. This calculator does not have a Computer Algebra System or CAS. So the results of all calculations will be displayed as decimal numbers, and that includes the square and other roots that are irrational numbers (square root of 2, 3, 5 7, etc.)

You cannot manipulate radicals on this calculator, whether for small numbers or large numbers. Sorry.

### Comma key on TI-84 Plus Siver Edition calculator.

The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.
