Koordinaatsüsteem

Koordinaatsüsteem is a framework used to define the position of points in space. It consists of a set of axes, which are lines along which measurements are made, and a reference point, known as the origin, from which measurements are taken. The most common type of coordinate system is the Cartesian coordinate system, which uses two or three perpendicular axes to define positions in two-dimensional (2D) or three-dimensional (3D) space, respectively. In a 2D Cartesian coordinate system, a point is represented by an ordered pair of numbers (x, y), where x is the distance along the horizontal axis and y is the distance along the vertical axis. In a 3D Cartesian coordinate system, a point is represented by an ordered triple of numbers (x, y, z), where z is the distance along the third axis, which is perpendicular to both the x and y axes. Other types of coordinate systems include polar coordinates, which use a radius and an angle to define a point's position, and spherical coordinates, which use a radius, an azimuthal angle, and a polar angle. Coordinate systems are widely used in mathematics, physics, engineering, and other fields to describe the positions and movements of objects in space. They provide a standardized way to communicate and analyze spatial information.
