Three sliders, a, b, and α adjust the general equation of a parabola.
a and b set the major and minor axis and α allows the parabola to rotate.

What are the setting ranges for a, b, and α to show a vertical parabola?
A horizontal parabola?
What settings changes are needed to set the rotation of the parabola to 45°, 120°, 215°, or 330°?
A parabola has a vertex, a focus, and a directrix, what setting does the b represent with respect to these values? What about the a value?
