Key Concepts. A parabola is the set of all points (x, y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0, 0) and the x -axis as its axis of symmetry can be used to graph the parabola. For the equation given, a = 1/8, and so the focal distance is 2. Add this value to h to find the focus: (3 + 2, 1) or (5, 1). To find the directrix, subtract the focal distance from Step 2 from h to find the equation of the directrix. Because this is a horizontal parabola and the axis of symmetry is horizontal, the directrix will be vertical.This CalcTown calculator calculates the focal length, ratio and effective aperture of a parabolic dish antenna.

Coming to the equation of parabola, If a parabola has a vertical axis, the standard form of the equation of the parabola is: (x – h) 2 = 4p(y – k), where p≠ 0. The vertex of this parabola is at (h, k).The focus is at (h, k + p).The directrix is the line y = k – p.The axis is the line x = h. f a parabola has a horizontal axis, the standard form of the equation of the …May 28, 2023 · Focus: The focus is a point along the axis of symmetry, inside the parabola, that is equal in distance from the vertex as is the directrix. So, if the directrix is 2 units away from the vertex, the focus is also 2 units away (and, as a result, 4 units away from the directrix).
