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

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

SOURCE: Find the antilog on the TI-84 Plus for finding pH in chemistry problems

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Press [math] [0] to put the calculator into equation solver. Then you input your equation in 0 = format. So, the equation x/3 - 1/5 = 4/3 would be input as 0 = x/3 - 1/5 - 4/3 . Then press [enter] .

To solve this with a ti-84 press [math] and select solve from the menu. This will open the equation solver. Type in your equation

(Note: you may need to put it in the form with 0=, So the equation would be 0 = 2c + 6 +7c - 8 ). Then press

enter or arrow down button.

The calculator cannot handle "plus or minus" in the same equation. If you need both, enter two equations into y=, one for plus and the other for minus.

If you wan to solve an equation using the SOLVE feature you enter it as follows (your example)

You should rewrite it as 5/4*X-18+3 (= 0). Implicitly, the calculator assumes that the right side is ZERO and you do not enter any right side nor an equal sign.

Type in

5/4 [*] [X,T,theta, n] -18 +3 [ALPHA] [ENTER] (SOLVE)

You should get an answer -780/47 or the decimal equivalent (depending on display mode.)

Hello,

Since you know about the catalog, that is where you find the equal sign, near the bottom of the list. It is faster if you scroll up from abs(.

Hope it helps.

The TI 83, 84 seris can not store more than 10 equations. the TI 86 and above can have infinate, but not the 83, 84s. If you have catalog help in your apps, you can run that, and it will be able to tell you all the syntax of every function it has.

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:

In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.
