This is a program for unit #2 of my math 20ap class. (#1 was Quadratic Equations, zip files either QUAD25.zip or QUADEQU.zip, depending on server and version)  You can expect a new program every so often as I engage in a new unit.  At the end of the term, I will combine all the programs into one big one, and call it MATH20AP.ZIP or something.

This program does everything I can think of relating to quadratic functions.  X and Y intercepts, vertex, symmetry, blah blah blah.  And yes, I do know that technically my formula is wrong.  I know it isn't A(X+P)+Q but A(X-P)+Q.  However, the latter just created too many input problems.  For the former, the variables are A=1, B=3, and C=2 when the equation is (X-3)+2, but everyone in my math class typed in 1,-3,2, and screamed at me when it didn't work.  So I changed it.


Revision History

v0.9B-The infamous input problem cited above.  I know it's technically right, but try telling that to someone who just screwed up 5 pages of math.  Also had problems with X and Y intercepts. Again, really angry students.  Well, that's the thankless life of a programmer who releases betas onto the unsuspecting populace after an hour of programming.
v1.0-"Fixed" the input problem. Fixed the X and Y intercepts.  Made it so you would exit when graphing so you could change the view window, etc.

Well, there is none.  Just don't seperate this file from the program, and if you do edit it, please send me a copy along with any comments you may have.  Thanks!
