In mathematics, the parabola (from the Greek παραβολή) is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. Given a point (the focus) and a corresponding line (the directrix) on the plane, the locus of points in that plane that are equidistant from them is a parabola. While the parabola isn't an important concept in abstract mathematics, it's seen with considerable fre… (More on Parabolas)
