Suppose a chord crosses a parabola perpendicular to its axis of symmetry. Let the length of the chord between the points where it intersects the parabola be c and the distance from the vertex of the parabola to the chord, measured along the axis of symmetry, be d. The focal length, f, of the parabola is given by Proof WebThe simplest equation for a parabola is y = x2 Turned on its side it becomes y2 = x (or y = √x for just the top half) A little more generally: y 2 = 4ax where a is the distance from the origin to the focus (and also from …
