Coordonnés

Coordonnés is a French word that translates to "coordinates" in English. In mathematics and geometry, coordinates are a set of values used to uniquely identify a point or a position in a coordinate system. The most common type of coordinate system is the Cartesian coordinate system, which uses perpendicular axes to define positions.

In a two-dimensional Cartesian system, a point is represented by an ordered pair of numbers (x, y), where 'x' represents the horizontal distance from the origin (the point where the axes intersect) and 'y' represents the vertical distance. For example, the point (3, 5) is located 3 units to the right of the origin and 5 units above it.

In three-dimensional space, a point is represented by an ordered triplet of numbers (x, y, z), adding a third axis perpendicular to the other two. This allows for the precise location of objects in three-dimensional space, crucial in fields like physics, engineering, and computer graphics.

The concept of coordonnées extends beyond simple geometric points. It is also fundamental in navigation, where latitude and longitude are used to specify locations on Earth. In computer science, coordinates are used to define the position of pixels on a screen or elements within a graphical user interface. The term can also be used more broadly to refer to any system of reference that allows for precise location or alignment.
