This applet demonstrates that the loci of points equidistant from the focus and directrix, is the same as Loci of points given by (at^2,2at)
show conic c and line d and vary r and observe how the points of intersection lie on the parabola.
also observe how varying t moves point P (at^2,2at) along the parabola.
