In the framework of a linear coordinate system, any point that is part of a certain line can be linked and symbolized by means of a real number (which will be positive if it is a point located to the right of O or negative if it is in the left portion). Descartes, as many of you will know, is often considered the father of analytic geometry. In a plane, the Cartesian coordinate X is called the abscissa, while the Cartesian coordinate Y is distinguished by the expression "ordinate".Įxperts in the field say that the Cartesian system has been named in honor of the philosopher, scientist and mathematician René Descartes ( 1596 - 1650), who sought to support his philosophical reasoning from a starting point on which to build all knowledge. The reference system in relation to an axis (a line), two (a plane) or three axes (in space) that are perpendicular to each other and that coincide at a certain point that is identified with the name of the origin of coordinates, it is known as Cartesian coordinates. In the year 1801 it was when this work was published, which is written in Latin, where it enters fully into what is the fundamental theorem of algebra. In the same way, the structure that he gave to Number Theory and the large number of publications he made should not be overlooked, including Disquisitiones arithmeticae. This last author has gone down in the history of Mathematics for various issues and among them it should be noted, without a doubt, the fact that he was the first scientist to carry out what is the proof of the fundamental theorem of algebra. However, we cannot ignore that, in one way or another, it also "drinks from the waters" of differential geometry, developed by the German mathematician Carl Friedrich Gauss, and of algebraic geometry. This area must be emphasized that it has its origin in Cartesian geometry, the movement that René Descartes would develop in the period between the 17th and 18th centuries. This is a scientific area that is responsible for carrying out the study of the various geometric figures through the use of a series of techniques, algebra and mathematical analysis, in what is a coordinate system. This term and many others, such as equations or axes, are all fundamental and key concepts in what is called analytical geometry. The so-called abscissa axis represents the horizontal coordinate axis. See the etymology of the corresponding lemma form.It is known as abscissa (word derived from the Latin abscissa, "cut") to a coordinate of horizontal direction that appears in a rectangular Cartesian plane and that is expressed as the distance that exists between a point and the vertical axis.
