In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the Greek mathematicians with this work culminating around BC, when Apollonius of Perga undertook a systematic study of their properties.

### Conic section – Wikipedia

Mathematics and its history 3rd ed. One of them is based on the converse of Pascal’s theorem, namely, if the points of intersection of opposite sides of a hexagon are collinear, then the six vertices lie on a conic. The most general equation is of the form .

Retrieved from ” https: The conic sections of the Euclidean plane have various distinguishing properties. Many of these have been used as the basis for a definition of the conic sections. Furthermore, each straight line intersects each conic section twice. In all cases, a and b are positive. To obtain the extended Euclidean plane, the absolute line is chosen to be the line at infinity of the Euclidean plane and the absolute points are two special points on that line called the circular points at infinity.

The great innovation of Diophantus is still keeping the algebraic statements rhetoric form of sentence structure, replaced with a series of magnitudes abbreviations, concepts and frequent operators, ie, starts the “syncopated algebra”.

In the Cartesian coordinate systemthe graph of a quadratic equation in two variables is always a conic section though it may be degenerate and seccciones conic sections arise in this way.

At every point of a point conic there is a unique tangent apolonko, and dually, on every line of a line conic there is a unique point called a point of contact. Yet another general method uses the polarity property to construct the tangent envelope of a conic a line conic.

If the intersection point is double, the line is said to be tangent and it is called the tangent line. Four points in the plane in general linear position determine a unique conic passing through the first three points and having the fourth point as its center.

### ¿Quién era Apolonio de Perga? by Jorge Loaisiga on Prezi

Matrix representation of conic sections. A non-degenerate conic is completely determined by five points in general position no three collinear in a plane and the system of conics which pass through a fixed set of four points again in a plane and no three collinear is called eprga pencil of conics. That is, there apllonio a projective transformation that will map any non-degenerate conic to any other non-degenerate conic. Greek mathematics contributed in the geometric language, all knowledge of elementary mathematics, that is, on the xecciones hand the synthetic plane geometry points, lines, polygons and circles and spatial planes, polyhedra and round bodies ; and on the other hand, an arithmetic and algebra, both with a geometric clothing, contributions that were made in the book “The Elements” of Euclid.

Wikimedia Commons has media related to Conic sections. The classification into elliptic, parabolic, and hyperbolic is pervasive in prega, and often divides a field into sharply appolonio subfields. An important theorem states that the tangent lines of a point conic form a line conic, and dually, the points of contact of a line conic form a point conic.

In the real projective plane, a point conic has the property that every line meets it in two points which may coincide, or may be complex and any set of points with this property is a point conic.

Aoolonio Wikipedia, the free encyclopedia. An instrument for drawing conic sections was first described in CE by the Islamic mathematician Al-Kuhi. Since five points determine a conic, a circle which may be degenerate is determined by three points. There are three types of conics, the ellipseparabolaand hyperbola. This symbolic representation can be made concrete with a slight abuse of notation using the same notation to denote the object as well as the equation defining the object.

The association of lines of the pencils can be extended to obtain other points on the ellipse. More technically, the set of points that are zeros of a quadratic form in any number of variables is called a quadricand the irreducible quadrics in a two dimensional projective space that is, having three variables are traditionally called conics. These standard forms can be written parametrically as. Von Staudt introduced this definition in Geometrie der Lage as part of his attempt to remove all metrical concepts from projective geometry. The eccentricity of an ellipse can be seen as a measure pergw how far the ellipse deviates from being circular.

In conicax of algebra, Diophantus made apolojio in his book arithmetic. After Thales, Pythagoras gives an advance mathematics with discoveries like the Pythagorean theorem, the discovery of irrational; also “The Pythagoreans developed a first group of four mathematical disciplines: The conkcas segment joining the vertices of a conic is called the major axisalso called transverse axis in the hyperbola. Unless otherwise stated, “conic” in this article will refer to a non-degenerate conic.

One way to do this is to introduce homogeneous coordinates and define a conic to be the set of points whose coordinates satisfy an irreducible quadratic equation in three variables or equivalently, the zeros of an irreducible quadratic form. Who is considered the first geometric theorems by logical reasoning such as: Using Steiner’s definition of a conic this locus of points will now be referred to as a point conic as the meet of corresponding rays of two related pencils, it is easy to dualize and obtain the corresponding envelope consisting of the joins of corresponding points of two related ranges points on a aploonio on different bases the lines the points are on.

The three types are then determined by how this line at infinity intersects the conic in the ssecciones space.
