Focus of a Parabola:In mathematics, the focus of a parabola is a point that can be used, along with a line called the directrix, to define the parabola. That is, a parabola is a set of points, such that each point on the parabola is the same distance from the focus of the ...
What is an equation of a parabola with the given vertex and focus Vertex:(0 0) Focus: (2.5 0) Focal Distance For a parabola, the distance between the vertex and the focus point of the parabola is known as the focal distance. This is also the distance between...
A parabola is a locus of points equidistant from both 1) a single point, called the focus of the parabola, and 2) a line, called the directrix of the parabola. What is the Focus and Directrix? The red point in the pictures below is the focus of the parabola and the red line is ...
one of the fixed points from which the distances to any point of a given curve, such as an ellipse or parabola, are connected by a linear relation. an element of a sentence that is given prominence by intonational or other means.
Focus and Directrix of a Parabola A parabola is a conic section that is generated by the intersection of the surface of a plane with a cone. A parabola is a plane curve that is formed when a point moves such that the distance between it and a fixed point equals the distance between it...
3.A central point or region, such as the point at which an earthquake starts. 4.MathematicsA fixed point or one of a pair of fixed points used in constructing a curve such as an ellipse, a parabola, or a hyperbola. The American Heritage® Student Science Dictionary, Second Edition. Cop...
(1) The focus of a curve of degree 2—an ellipse, a hyperbola, or a parabola—is a pointFlying in the plane of the curve and possessing the property that the ratio of the distance between any point on the curve andFto the distance to the directrix is a constant equal to the eccentri...
A special point used to construct and define a conic section. A parabola has one focus. An ellipse has two, and so does a hyperbola. A circle can be thought of as having one focus at its center.See alsoFocus of a parabola, foci of an ellipse, foci of a hyperbola...
