A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numericalcoordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis plural axes of the system, and the point where they meet is its origin, at ordered pair 0, 0. The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin. One can use the same principle to specify the position of any point in three dimensionalspace by three Cartesian coordinates, its signed distances to three mutually perpendicular planes or, equivalently, by its perpendicular projection onto three mutually perpendicular lines. In general, n Cartesian coordinates an element of real n space specify the point in an n dimensional Euclidean space for any dimensionn. These coordinates are equal, up to sign, to distances from the point to n mutually perpendicular hyperplanes.

Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is x a2 y b2 r. The invention of Cartesian coordinates in the 1. Ren Descartes Latinized name Cartesius revolutionized mathematics by providing the first systematic link between Euclidean geometry and algebra. Using the Cartesian coordinate system, geometric shapes such as curves can be described by Cartesian equations algebraic equations involving the coordinates of the points lying on the shape. For example, a circle of radius 2, centered at the origin of the plane, may be described as the set of all points whose coordinates x and y satisfy the equation x. Cartesian coordinates are the foundation of analytic geometry, and provide enlightening geometric interpretations for many other branches of mathematics, such as linear algebra, complex analysis, differential geometry, multivariate calculus, group theory and more. A familiar example is the concept of the graph of a function. Cartesian coordinates are also essential tools for most applied disciplines that deal with geometry, including astronomy, physics, engineering and many more. They are the most common coordinate system used in computer graphics, computer aided geometric design and other geometry related data processing. HistoryeditNicole Oresme, a French cleric and friend of the Dauphin later to become King Charles V of the 1. Century, used constructions similar to Cartesian coordinates well before the time of Descartes and Fermat. The adjective Cartesian refers to the French mathematician and philosopher. Ren Descartes who published this idea in 1. It was independently discovered by Pierre de Fermat, who also worked in three dimensions, although Fermat did not publish the discovery. Both authors used a single axis in their treatments and have a variable length measured in reference to this axis. The concept of using a pair of axes was introduced later, after Descartes La Gomtrie was translated into Latin in 1. Frans van Schooten and his students. These commentators introduced several concepts while trying to clarify the ideas contained in Descartes work. Many other coordinate systems have been developed since Descartes, such as the polar coordinates for the plane, and the spherical and cylindrical coordinates for three dimensional space. The development of the Cartesian coordinate system would play a fundamental role in the development of the Calculus by Isaac Newton and Gottfried Wilhelm Leibniz. The two coordinate description of the plane was later generalized into the concept of vector spaces. DescriptioneditOne dimension editChoosing a Cartesian coordinate system for a one dimensional space  that is, for a straight lineinvolves choosing a point O of the line the origin, a unit of length, and an orientation for the line. An orientation chooses which of the two half lines determined by O is the positive, and which is negative we then say that the line is oriented or points from the negative half towards the positive half. Then each point P of the line can be specified by its distance from O, taken with a or sign depending on which half line contains P. A line with a chosen Cartesian system is called a number line. Every real number has a unique location on the line. Conversely, every point on the line can be interpreted as a number in an ordered continuum such as the real numbers. Two dimensions editThe Cartesian coordinate system in two dimensions also called a rectangular coordinate system or an orthogonal coordinate system5 is defined by an ordered pair of perpendicular lines axes, a single unit of length for both axes, and an orientation for each axis. Early systems allowed oblique axes, that is, axes that did not meet at right angles. The lines are commonly referred to as the x and y axes where the x axis is taken to be horizontal and the y axis is taken to be vertical. The point where the axes meet is taken as the origin for both, thus turning each axis into a number line. For a given point P, a line is drawn through P perpendicular to the x axis to meet it at X and second line is drawn through P perpendicular to the y axis to meet it at Y. The coordinates of P are then X and Y interpreted as numbers x and y on the corresponding number lines. The coordinates are written as an ordered pair x, y. The point where the axes meet is the common origin of the two number lines and is simply called the origin. It is often labeled O and if so then the axes are called Ox and Oy. A plane with x and y axes defined is often referred to as the Cartesian plane or xy plane. The value of x is called the x coordinate or abscissa and the value of y is called the y coordinate or ordinate. The choices of letters come from the original convention, which is to use the latter part of the alphabet to indicate unknown values. The first part of the alphabet was used to designate known values. In the Cartesian plane, reference is sometimes made to a unit circle or a unit hyperbola. If a point on a two dimensional plane is x, y, then the distance of the point from the x axis is y and the distance of the point from the y axis is x. Three dimensions edit. A three dimensional Cartesian coordinate system, with origin O and axis lines X, Y and Z, oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinates x 2, y 3, and z 4, or 2, 3, 4. Choosing a Cartesian coordinate system for a three dimensional space means choosing an ordered triplet of lines axes that are pair wise perpendicular, have a single unit of length for all three axes and have an orientation for each axis. As in the two dimensional case, each axis becomes a number line. The coordinates of a point P are obtained by drawing a line through P perpendicular to each coordinate axis, and reading the points where these lines meet the axes as three numbers of these number lines. Alternatively, the coordinates of a point P can also be taken as the signed distances from P to the three planes defined by the three axes.
