kartézián
Kartézián is a term often associated with René Descartes, a prominent philosopher and mathematician. It is primarily used to refer to the Cartesian coordinate system, which he developed. This system provides a way to uniquely identify points in a plane or in space using numbers. These numbers are called coordinates. In a two-dimensional Cartesian plane, a point is identified by an ordered pair (x, y), where 'x' represents its horizontal position and 'y' represents its vertical position relative to a central origin. Similarly, in three dimensions, a point is represented by an ordered triple (x, y, z).
The Cartesian coordinate system is fundamental to analytic geometry, a field that bridges algebra and geometry.
