SOURCE: Change TI 84 OS to TI 89 OS??

And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or and spare your TI84PLus SE.

Binompdf ( says n:......p:.....x:..... How can I enable this guided input on my TI-84?

In the older versions of the OS, the command binompdf( displays a command line where the user is expected to enter the arguments respecting the syntax of the command. In the more recent versions of the OS (the most recent is 2.55 MP) the user enters the input over three lines.
I suggest you upgrade the OS of your calculator to the latest version available on the website.
To upgrade, insert fresh AA batteries (or just good batteries), run TI connect on your computer, connect the calculator to the computer and click the update button on TI connect main screen. It will download and update the OS.

I have a TI-84 calculator. I can't figure out the exact buttons to press to find the sec of -1.2. It is supposed to be an answer in degrees.

First, check if the calculator is in degrees. Do this by pressing mode and selecting degrees (it should be about the third option down)

The TI-84 doesn't have a dedicated button for secant so you will just have to enter it as 1/cos(-1.2) or cos(-1.2)^-1

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.

How do I on a TI-84 Plus Simplify Fractions

Enter the fraction for example: enter 8/12.
The answer will be .666666
Then click Math (which is located under the Alpha button).
Click the ->Frac button (the first one).
It should come up as Ans->Frac.
Click Enter.
It should now read 2/3 which is 8/12 reduced.
Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition

Garbage Collecting

graphing calulators work much like computers. The have RAM space so they can remember what you have done recently and stuff like that. So when it's garbage collecting it means it's trying to find more space. This generally means that you don't have much much ARC or RAM space left. You can see this under your memerory manager. (2nd + enter) then you can reset your calculaor(2nd plus 7 1 2) or you can go to memory manager and unarchive your programs. Fur an example you have TI 84. Most new TI 84 have sientific tools. so if you don't you it take away the archive (*) by pressing enter and then hit DEL. the more RAM space and ARC space should make it so it doens't garababe collect. Hope this works. i can help you more if this doesn't work. GOOD LUCK
