[Off-Topic] Ti84 Calculator

[ctccromer]

Hey guys. I just recently looked up how to code on my graphing calculator -- I'm working on writing a program for each chapter in my AP Physics class, with a list of each equation in the chapter. Once an equation is chosen, it asks you which variable is missing, prompts the other variables, and spits out the answer. Useful for 1) having the base equations always there, and 2) quick answers

However I've run into a couple issues, so if you happen to know how to help me out, I'd appreciate it

1) Somehow, SOME WAY, I accidentally wiped my calculator. Shows the start-up screen with "select alpha f1-f4" and everything. All my programs are gone... Any idea how I even did this so I know what to avoid? Is there any way to restore its previous state, see a list of the programs deleted, or anything? :/ hours wasted..

2) To show a list of equations, I'm using Program -> "Menu(" and making each equation a list item on the menu "EQUATIONS". The only issue with this is that the longer equations go off the screen instead of wrapping around to a new line. Is there any way to make them wrap around, decrease the text size, etc? Or do I have to create extra, useless "lists" with the rest of the equation to fake it wrapping around?

3) I read that it's possible to code the programs on the computer, then transfer them over. This would make huge programs like what I'm trying to make much simpler (and easier in the case of #1...). To do this, do I simply code it in anything, such as Notepad, and then transfer it over? Or do I need a specific program from TI's website?

Thanks for the help. And I'll leave this link as a resource for anyone else seeking information on the subject: http://answers.yahoo.com/question/in...3195411AAxaxup
