THIS WILL HELP YOU 4 SHO

the best way to get all your applications back is to link your friend's ti-84 plus and make a file backup, ( do this by first installing Ti graphing Product CD wich is included with the calculator) after this just connect your calculator and store the files back onto your calculator! ZOMG??? IS it that easy???
yes it is, just apply some clear thinking and ull be just as smart as i am

You answered my question but the comma key on the TI-84 plus siver edition is not seen over top of the #7 key. Where do I find it?

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.

The best way to solve this problem is to get a 2nd TI-84 to link into with the linking USB cable. Then turn on working calc press the 2nd button then link button (or the XTON) variable button. Scroll up to option G: SEND OS "DO NOT HIT ENTER YET" and then remove and replace one battery from the non-working unit. NEXT press enter on working unit to SEND OS.

The easiest way to fix this is through the Apps menu. Hit the apps key, then scroll down until you see any language(espanol, Deutsch, etc.). It should give you the option of switching to either that language or restoring to English. I just tried this on a calculator that was set to German. I hit Apps and scrolled down until I recognized the option for Spanish, and it still worked. It let me switch back to English.
Hope this works for you.

Sorry, but you cannot. However there is a program that you can download and install on your calculator. YOU DO THAT AT YOUR OWN RISK.

TI-84 Incorrect sin/cos/tan values

Both of my TI-84 Silver Editions have incorrect values for the sin/cos/tan functions. A lot of times the values come up negative. Any idea as to what is going on? I have tried clearing the RAM but it didn't fix the problem.

Ex: sin(37)= -.6435381334

What is so surprising? The sine and cosine functions have ranges that span the closed interval [-1,1]. As to the tangent function, its range is the the whole real line.

This being said, you should keep in mind that there are three angle units: the degree, the radian, and the grad.
When you want to calculate the sine, cosine, or tangent of a number, that number is not just a number. It is an angle, and as an angle it has a unit.

For this reason a calculator generally has two angle units defined (degree and radian), and possibly the grad. BEFORE calculating any trigonometric function you must ascertain that the angle is in the correct unit.

Clearly, in the problem you are trying to solve angle values are given in degrees, but your calculator is configured to interpret angles values in radians.

To set the default angle unit to degree press [MODE] , then press down arrow twice to reach the line (radian, degree). Highlight the word degree and press [ENTER] to set the default angle unit to degree.

Unfortunately the TI 8xPLUS family of calculators does not have a status bar on screen to remind you of the modes, and if you do not remember to check the current unit you get errors (at least unexpected results).

However, there is a way to avoid the errors and that is to enter the unit explicitly after the angle value. To do that you press [2nd][APPS] to open the (ANGLE) menu list. Try it.

  1. First item in list is the degree symbol, a raised 0
  2. 2nd is the minute, an apostrophe
  3. 3rd is radian, a raised r
By selecting the degree symbol and pressing [ENTER}, that symbol echoes on the screen just after the angle value. Closing the right parenthesis of the trigonometric function and pressing [ENTER] will give you the result in the correct unit of your choice. This can be done regardless of the default unit the calculator is configured for.

TI 84 Won't turn back on

I went into the application Francais and the screen showed up but when I tried to exit out of the application it would not let me. When I pushed the 2nd button I saw a 6 appear on the top right hand side of the screen. When I pushed the down arrow I saw the number 4. I did this several more times until the number was down to 1. When I pushed the down arrow again, the calculator completely shut off. I've tried to connect to the computer and to another calculator to turn it on but it won't do anything. I've manually restarted it and it still won't work. Will you help me?

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.
