Coordinates are a set of values used to uniquely identify a position of a point or other geometric object on a space. The most common type of coordinate system is the Cartesian coordinate system, which uses perpendicular axes to define locations. For example, in a two-dimensional Cartesian system, a point is located by its distance along the x-axis and its distance along the y-axis, denoted as (x, y). In three dimensions, a third axis, the z-axis, is added, and a point is represented as (x, y, z).

Coordinate systems are fundamental in many fields, including mathematics, physics, engineering, geography, and computer graphics. They provide a framework for describing spatial relationships and performing calculations related to position, distance, and shape. Different types of coordinate systems exist beyond the Cartesian system. Polar coordinates, for instance, define a point by its distance from an origin and the angle it makes with a reference direction.

In geography, the most well-known coordinate system is the latitude and longitude system, which specifies locations on the Earth's surface. Latitude measures the angular distance north or south of the equator, while longitude measures the angular distance east or west of the prime meridian. This system is crucial for navigation, mapping, and global positioning. In computer science, coordinates are used extensively in graphics to position elements on a screen or in a virtual environment. The choice of coordinate system depends on the specific application and the nature of the problem being addressed.
