Title

ConicSections v5.0 Final (shows work)

Description

This program performs various Conic Section operations dealing with Parabolas (completing the square), Ellipses/Circles, and Hyperbolas (shows all work in calculations) and reports graphing information on the equation. This program also includes an equation identifier. Operations: [Parabolas] Ax^2+Bx+C > a(xh)^2+k (Completing the square) , [Ellipses/Circles] Ax^2+By^2+Cx+Dy+E > ((xh)^2/a^2)+((xh)^2/b^2)=1 , [Hyperbolas] Ax^2+By^2+Cx+Dy+E > ((xh)^2/a^2)((xh)^2/b^2)=1 * Operations show all work!!!

I loved this app and it does a great job showing how the equations are solved, but there is only one problem that I found and that is with the "Ellipses/Circles" solver. It actually turns the equation into a Hyperbola by incorrectly subtracting the second squared portion of the equation instead of adding it.
This is the correct formula:
Ax^2+By^2+Cx+Dy+E > ((xh)^2/a^2)+((xh)^2/b^2)=1
This is what the program actually does:
Ax^2+By^2+Cx+Dy+E > ((xh)^2/a^2)((xh)^2/b^2)=1
The other parts work great including the actual Hyperbola solver.
