--------------------- Parabola 4.0 ---------------------
-------- John McCord <jpmccord@worldnet.att.net> -------

     At first, this was just a small program to get me
through class. As more and more people wanted it, I kept
adding to it. As far as I'm concerned, this is the best
and only Quadratic/Parabolic program you need on your
calculator! It does everything! It may even solve for a
couple of things you've never heard of, such as P, the
focus, and the directrix.
     My battery died about two weeks ago and I lost
everything I had, including this program. It didn't take
me long to get it back, only this time I made it easily
10 times better! It is now much more organized, solves
for answers in fractions instead of decimals, and it
even solves for X= parabolas!  (You know, the ones that
go left and right instead of up and down...)
     Questions?  Comments?  Concerns?  Email me! In the
meantime, check out my TI page! Lots of info on all 9
TI graphing calculators!
