xycoördinaten

Xy-coördinaten, also known as Cartesian coordinates, are a system used to determine the position of a point in a two-dimensional space. The system is named after René Descartes, who introduced it in the 17th century. In this system, each point is represented by an ordered pair of numbers (x, y), where x is the horizontal coordinate and y is the vertical coordinate. The origin, or the point where the x and y axes intersect, has coordinates (0, 0). The x-axis extends horizontally to the right and left, while the y-axis extends vertically upwards and downwards. The coordinates can be positive or negative, depending on the position of the point relative to the origin. Xy-coördinaten are widely used in mathematics, physics, engineering, and computer science for various applications, including graphing functions, plotting data, and defining shapes and figures. The system can also be extended to three-dimensional space, where each point is represented by an ordered triple of numbers (x, y, z).
