Focus directrix form of a parabola
WebOct 6, 2024 · A parabola is defined as the locus (or collection) of points equidistant from a given point (the focus) and a given line (the directrix). Another important point is the vertex or turning point of the parabola. If the equation of a parabola is given in standard form then the vertex will be (h, k). WebThe directrix of a parabola is a line perpendicular to the axis of symmetry used in the definition of the parabola. If the axis of symmetry is vertical, the directrix is horizontal. When the focus is above the directrix, as shown …
