My teacher's TI84+ SE calculator looks like this when the Y= button is pressed: (the image is attached, just in case it's removed from imgur)



This is not running a program or anything, that is just the screen after Y= is pressed.

As you can see, this is a very useful program, and I would like to have it on my own calculator (TI84+ SE C), and my friend's calculator (TI84+), but do not know how since it is not just a program.

I have her caculator until tomorrow (2015-03-13) or possibly longer if no one has figured it out until then; just let me know what you need a list of (programs, flash apps, whatever, I don't know) to make my and my friend's calculator like my teacher's.

Any help would be appreciated.
