The inputs above will be hidden when the program finally gets launched. Currently, I am not hiding them even when you close the calculator. The purpose of the inputs is to help in debugging. This allows you to enter simple code on the calculator screen but the program translates the input to javascript math. Give it a try and see if you notice any obvious problems or have suggestions for improvements.

The vertex of the parabola is at (h,k). The distance (p) from the focus to the vertex
is the same as the the distance from the vertex to the directrix. The focus and the
directix are equidistant from any point on the curve. Try different values of h, k and
p to see their effect.
