## Equation of a parabola from focus & directrix

In mathematics , a parabola is a plane curve which is mirror-symmetrical and is approximately U- shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point the focus and a line the directrix. The focus does not lie on the directrix. The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus.

Did you know that the Olympic torch is lit several months before the start of the games? The ceremonial method for lighting the flame is the same as in ancient times. The ceremony takes place at the Temple of Hera in Olympia, Greece, and is rooted in Greek mythology, paying tribute to Prometheus, who stole fire from Zeus to give to all humans. Parabolic mirrors or reflectors are able to capture energy and focus it to a single point. The advantages of this property are evidenced by the vast list of parabolic objects we use every day: satellite dishes, suspension bridges, telescopes, microphones, spotlights, and car headlights, to name a few.

## 8.4: The Parabola

Number and Algebra : Module 35 Year : PDF Version of module. The parabola is a curve that was known and studied in antiquity. It arises from the dissection of an upright cone. With the advent of coordinate geometry, the parabola arose naturally as the graph of a quadratic function.

These standard forms are given below, along with their general graphs and key features. Identify and label the vertex , axis of symmetry , focus , directrix , and endpoints of the focal diameter. Thus, the axis of symmetry is parallel to the x -axis. It follows that:.

With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and write the parabola algebraically. Just as a quadratic equation can map a parabola, the parabola's points can help write a corresponding quadratic equation. Find an equation describing the door given that is 4 feet across and 8 feet high in the center. The equation of a horizontal ellipse in standard form is where the center has coordinates the major axis has length 2 a, the minor axis has length 2 b , and the.
