Document Summary

Objective 1 determining the equation of a parabola with vertical axis of symmetry. We will now look at parabolas from a geometric perspective. When a plane is parallel to an element of a cone, the plane will intersect the cone in the shape of a parabola. The set of points that define the parabola formed by the intersection described above is stated in the following geometric definition of the parabola. A parabola is the set of all points in a plane equidistant from a fixed point f and a fixed line d. The fixed point is called the focus and the fixed line is called the directrix. P to the directrix. on the parabola to the focus. The distance from any point is the same as the distance from point. We can see that for any point focus is exactly the same as the distance from point p to the directrix.
