What is Coordinate system?
[[File:Equatorial coordinate system.png|thumb|Equatorial coordinate system]] A '''coordinate system''' is a system of numbers used to uniquely determine the position of a point. For [[2D|two-dimensional]] systems, the numbers ([[scalar]]s) are in ordered pairs. More [[dimension]]s call for more numbers. For example, (3) is one-dimensional, (1, 4) is two-dimensional, (1, 5, 9) is three-dimensional, (2, 6, 5, 3) is four-dimensional, and (5, 8, 9, 7, 9) is five-dimensional. ==Related pages== * [[Analytic geometry]] * [[Cartesian coordinate system]] * [[Celestial coordinate system]] * [[Polar coordinate system]] * [[Spherical coordinate system]] [[Category:Coordinate systems]] {{math-stub}}
