This conic grapher was made by Stephen Dalton.  Please don't alter it;
it is the result of four hours of initial inspiration and countless
hours since then tweaking and making just-so adjustments.  You can give
it to anyone you darn well please, but just leave the program as it is.
If you do feel the need to change the source, then contact me at
misteryorp@hotmail.com.  Tell me the changes that you wish to make, how
you will implement them, and I will, in all likelihoOd, let you make
them.  One thing I will NOT allow under any circumstance is the removal
of my name from the title screen.  Please, don't take it away.  This
grapher really is a labor of love.

Upcoming projects:

I'm looking to come out with a rotation program where you simply enter
the rotation angle you wish the curve (or otherwise) to tilt at, and
(after some 500 years of waiting for the calc to slosh through all the
code :-) it shows the graph rotated at the correct angle.  Before I do 
this with a normal graph, however, I'm trying to do it with conic 
sections.  Anybody interested in helping me with this project, please
contact me at the address given before (and at the end of the message).
Note: This project is in the VERY early stages of development (I can't
figure out how to make my 83+ complete the square without crashing), so
any help at all would be greatly appreciated.

Other than that?  Well, nothing, really....

Send all of your suggestions for BASIC programs to:

misteryorp@hotmail.com

I will also (attempt to) debug any code you want me to, but it has to
be in TI-BASIC until I learn assembly.  Just put my name in the program
as the debugger (If there isn't a title screen, then don't even bother)


Just some final notes:

Most of the time, when the conics require multiple equations to be
expressed in function format, the curves will not close entirely.
Just use your imagination.  I'm thinking of making a box drawer to
govern the paths of the hyperbolas so that it seems as though they
close (heehee!).
