Exercise: Given a focus at (0,1) and a directrix y=-1, find the equation of the parabola. How to do it: draw a figure showing a generic point P on the parabola, with coordinates (x,y). Calculate its distance to the focus, its distance to the directrix, set those equal, and simplify.

test the vertex-directrix form of parabola equation by choosing random values of the directrix' length and the coordinates of the vertex, using those values in writing vertex-directrix form of parabolic equations, and then by using graphing calculators identifying the type of curves described by those equations.
  • If the focus of a parabola is at the point a, b and the directrix, the directrix, directrix is the line y equals k. We've shown in other videos with a little bit of hairy algebra that the equation of the parabola in a form like this is going to be y is equal to one over two times b minus k. This b minus k is then the...
  • A parabola is the set of all points in a plane and a given line. From the geometric point of view, the given point is the focus of the parabola and the given line is its directrix. It can be shown that the line of symmetry of the parabola is the line perpendicular to the directrix through the

    A parabolae plural parabolas or parabola is a two-dimensional, mirror-symmetrical curve. It can be in any orientation in its plane and approximately U-shaped. The parabola calculator to find the vertex, Focus, Directrix, Intercepts of a parabola you enter.

    In this problem, given the focus at (-7,5) and directrix at y = -11. then it is implied that the parabola is facing upwards. The vertex hence is at the middle of the focus and the directrix, hence at (-7, -3). The general formula of the parabola is y-k = 4a (x-h)^2. SUbstituting, y + 3 = 1/30 * (x+7)^2.
