Programming the TI-83+ SE for Projectile Motion

[Drayakir]

Hello, I was wondering if anyone could help me out with this:

I have a TI-83+ SE. I have gotten the formula for the path of a projectile without air-resistance. It is:

y= ((Voy)/(Vox))X)-(g/(2(Vox^2)X^2)))

Now, I have a question. How do I program it to make it graph the parabola that I am supposed to get, and how can I get it to find me undefined variables (I have a basic grasp of programming, though this is beyond my league).

Any help would be greatly appreciated, thanks.

Or maybe a link to a website that has these?

Honey, I think your problem is that most of us who use graphing calculators don't use TI. I use the HP-48 series, personally.

It's probably not much help, but I'd suggest that you (a) consult the manual and (b) talk to your classmates. Generally speaking, the best way to learn to program something is to try things out. You fail a lot, but even your failures teach you something, and you'll remember it longer and better.
