 Filename conicsectionsv5.0final.zip (Download) 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(x-h)^2+k (Completing the square) , [Ellipses/Circles]- Ax^2+By^2+Cx+Dy+E --> ((x-h)^2/a^2)+((x-h)^2/b^2)=1 , [Hyperbolas]- Ax^2+By^2+Cx+Dy+E --> ((x-h)^2/a^2)-((x-h)^2/b^2)=1 * Operations show all work!!!

 Review by Richard Wade Reviewed on 2012-06-28 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 --> ((x-h)^2/a^2)+((x-h)^2/b^2)=1 This is what the program actually does: Ax^2+By^2+Cx+Dy+E --> ((x-h)^2/a^2)-((x-h)^2/b^2)=1 The other parts work great including the actual Hyperbola solver.
