Parabola Pro

Features Parabola Pro

A parabola is a U-shaped curve, which can be described by the mathematical equation y = A x^2 + B x + C where A, B, and C are parameters that determine the precise shape of the parabola.
This app is designed for anyone who wants to really understand parabolas.
You can change the parabola parameters using sliders and immediately see the form of the parabola.
The app identifies the parabola’s roots, displays the discriminant and clarifies the relationship between the sign of the discriminant and the number of roots.
You can also study the special cases when the parabola degenerates into straight lines.
An extensive help screen walks you through initial experimentation.
