Equation directrix of a parabola
WebAs can be seen in the diagram, the parabola has focus at (a, 0) with a > 0. Also, the directrix x = – a. Let F be the focus and l, the directrix. Also, let FM be perpendicular to the directrix and bisect FM at point O. Produce MO to X. You can download the Parabola Cheat Sheet by clicking on the download button below Web1.) Parabola - A parabola is the set of all points (h, k) that are equidistant from a fixed line called the directrix and a fixed point called the focus (not on the line.) 2.) Axis of symmetry - A line passing through the focus and being perpendicular . to the directrix. 3.) The standard equation of a parabola (with the vertex at the origin). a.)
