A kind of curve; one of the conic sections formed by the intersection of the surface of a cone with a plane parallel to one of its sides. It is a curve, any point of which is equally distant from a fixed point, called the focus, and a fixed straight line, called the directrix. See Focus.

One of a group of curves defined by the equation y = axn where n is a positive whole number or a positive fraction. For the cubical parabola n = 3; for the semicubical parabola n = 3/2. See under Cubical, and Semicubical. The parabolas have infinite branches, but no rectilineal asymptotes.

The set of points equidistance from a focus and a directrix.

The graph of a quadratic function in two dimensions. In higher dimensions, a parabaloid.

set of points equal distance from a focus and a directrix

Conic section formed by a plane passing parallel to one side of a cone. The eccentricity of a parabola equals 1.

A shape like a shallow bowl that focuses incoming signals to a common focal point.

One of two conic sections for which there is only one closed end. At the other, or open, end, the two sides of the parabola extend into infinity, parallel to each other.

A geometric shape formed by the intersection of a cone by a plane parallel to its side.

The intersection of a conical surface and a plane parallel to an element of the surface.

Set of points equally distant from a focus and a directrix.

The mathematical curve whose graph has y proportional to x2.

A parabola is the curve you get when you graph a quadratic equation.

A curve of the form Y = u + vX + wX², where u, v and w are constants, X and Y the variables. The symbiosis between kinetic and gravitational energies in a simple harmonic system is an example of a parabolic relationship.

(n) A single-curved surface primitive, defined as the curve of intersection created when a plane intersects a right circular cone parallel to one of the cone's elements.

The set of all points in a plane that are the same distance from a point (focus) as they are from a given line (directrix). it is the graph of a quadratic function having a U shape.

The curve formed by the surface of a right circular cone when it is sliced by a plane which is parallel to a side of the cone. A parabola is also the curve formed by all the points in a plane which are the same distance from a line and a point not on that line.

A conic section of eccentricity 1.0; the curve of the intersection between a circular cone and a plane parallel to a straight line in the surface of the cone.

A form of arch defined by a moving point which remains equidistant from a fixed point inside the arch and a moving point along a line. This shape when inverted into an arch structure results in a form which allows equal vertical loading along its length.

the graph of a quadratic equation; the graph is shaped like a "U" and can open either up or down. If it opens up it has a maximum value, a peak so-to-speak. If it opens down it has a minimum value. You can tell much of this just from looking at the equation.

A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line: the intersection of a right circular cone with a plane parallel to an element of the cone.

The U-shaped curve in the plane given by the equation of the parabolic form.

The shape of the graph of a quadratic or degree 2 equation. Parallel Lines Lines in the same plane that never intersect. The slope of each line has the same value, i.e. m1= m2

An open plane curve formed by the intersection of a cone with a plane parallel to its side.

The geometric shape that has the property of reflecting all signals parallel to its axis to one point, the focal point.

The parabola (from the Greek: Ï€Î±ÏÎ±Î²Î¿Î»Î®) is a conic section generated by the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. A parabola can also be defined as locus of points in a plane which are equidistant from a given point (the focus) and a given line (the directrix).
