Sep 06, 2002 · Proposition 3. 7If from a point on a parabola a straight line be drawn which is either itself the axis or parallel to the axis, as PV, and if from two other points Q, Q' on the parabola straight lines be drawn parallel to the tangent at P and meeting PV in V, V' respectively, then. And these propositions are proved in the elements of conics. The standard equation of a parabola with vertex at the origin and vertical orientation is 4py = x 2, where p is the distance between the vertex and the origin. When the vertex is not at the origin, but at the point (h, k), the standard form of the equation of the parabola is 4p( y – k) = ( x – h) 2 .

The parabola results when the plane is parallel to a generating line of the cone. If the focus of the parabola is taken as the centre of inversion, the parabola inverts to a cardioid. This exactly means that the directrix is the polar of the focus, while the focus is the pole of the directrix with respect to the parabola. The absolute value of p is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on p tells me which way the parabola faces.) Since the focus and directrix are two units apart, then this distance has to be one unit, so | p | = 1.
