Conic section

Conic Section - One of four kinds of curves (circle, ellipse, hyperbola, and parabola) that can be formed by slicing a right circular cone with a plane ...

conic section: any of the range of geometric curves produced by the intersection of plane with a cone (i.e. circles, ellipses, parabolas and hyperbolas). co-ordinates: a system of measurements used to describe any point in two or three dimensions.

Conic Sections -- The family of curves generated by planes intersecting with a cone. Several cases are distinguished, depending on the angle between the plane and the axis of the cone.

conic section The curve of intersection between a circular cone and a plane; this curve can be a circle, ellipse, parabola, or hyperbola. conjunction ...

The best conic section representing the path of the comet at a given instant is known as the osculating orbit.

Five coaxial conic sections can form an X-ray image. [A] True [B] False The first target of observation by an imaging X-ray system was: ...

Conic Sections The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line.

See conic section. The limiting case occurs when the point is on the line, in which case the parabola becomes a straight line. parabolic Pertaining to, or shaped like, a parabola.

Originally called conic section. The conic sections are the ellipse, the parabola, and the hyperbola, curves that are used to describe the path or bodies moving in space.

He understood the parabola, both in terms of conic sections and in terms of the ordinate (y) varying as the square of the abscissa (x).

With two bodies, an orbit is a conic section. The orbit can be open (so the object never returns) or closed (returning), depending on the total kinetic + potential energy of the system.

Euclid also wrote works on perspective, conic sections, spherical geometry, and possibly quadric surfaces. Neither the year nor place of his birth have been established, nor the circumstances of his death. The Elements ...

In astrodynamics, under standard assumptions in astrodynamics, any orbit must be of conic section shape. The eccentricity of this conic section, the orbit's eccentricity, is an important parameter of the orbit that defines its absolute shape.... (i.e.

PARABOLA A parabola is a conic section, a curve that is a set of points (P) such that the distance from a line (the directrix) to P is equal to the distance from P to focus F. Parabolas have an eccentricity of 1.

HYPERBOLA A hyperbola is a conic section (the intersection of a cone with a plane) that has two mirror-image branches. Hyperbolas have an eccentricity greater than 1. HYPERBOLIC ORBIT A hyperbolic orbit is an in which the is greater than 1.

If two bodies interact gravitationally, each will describe an orbit that is a conic section about the common mass of the pair. If the bodies are permanently associated, their orbits will be ellipses.

A number used in optics to specify the shape of a surface which is a conic section, i.e. parabolic, hyperbolic, elliptical. Conic sections are obtained by slicing through a cone at the appropriate angle. Conifold Transition ...

Hypatia wrote commentaries on the astronomical canon of Ptolemy and did work on conic sections . Her works are lost, but are referred to in the Suda lexicon.

In his Principia Mathematica of 1687, Isaac Newton proved that an object moving under the influence of his inverse square law of universal gravitation must trace out an orbit shaped like one of the conic sections, ...
