Parabola with axis parallel to y -axis; p is the semi-latus rectum In Cartesian coordinates, if the vertex is the origin and the directrix has the equation , then, by examining the case , the focus is on the positive -axis, with , where is the focal length. The above geometric characterization implies that a point is on the parabola if and only if Solving for ...
A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point and a fixed line. Its general equation is of the form y^2 = 4ax (if it opens left/right) or of the form x^2 = 4ay (if it opens up/down)
Parabolas are a particular type of geometric curve, modelled by quadratic equations. Parabolas are fundamental to satellite dishes and headlights.
Learn about parabolas, their properties, and how to graph them in this introductory lesson on quadratic functions and equations.
parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone—that is, the cone’s surface.
This curve is a parabola (Figure 12 3 2). Figure 12 3 2: Parabola Like the ellipse and hyperbola, the parabola can also be defined by a set of points in the coordinate plane. 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.
