	Cartesian coordinate system - Wikipedia, the free encyclopedia
		Cartesian means relating to the French mathematician and philosopher Descartes, who, among other things, worked to merge algebra and Euclidean geometry.
		The modern Cartesian coordinate system in two dimensions (also called a rectangular coordinate system) is commonly defined by two axes, at right angles to each other, forming a plane (an xy-plane).
		It may be interesting to note that some have indicated that the master artists of the Renaissance used a grid, in the form of a wire mesh, as a tool for breaking up the component parts of their subjects they painted--a trade secret.

	Coordinates (mathematics) - Wikipedia, the free encyclopedia
		The coordinates of a point are the components of a tuple of numbers used to represent the location of the point in the plane or space.
		The polar coordinate systems are coordinate systems in which a point is identified by a distance from some fixed feature in space and one or more subtended angles.
		In terms of the Cartesian coordinate system, one usually picks O to be the origin (0,0) and L to be the positive x-axis (the right half of the x-axis).

	Cartesian coordinates
		In coordinate geometry, components used to define the position of a point by its perpendicular distance from a set of two or more axes, or reference lines.
		The Cartesian coordinate system can be extended to any finite number of dimensions (axes), and is used thus in theoretical mathematics.
		Coordinates can be negative numbers, or a positive and a negative; for example (−4, −7), where the point would be to the left of and below zero on the axes.

	GLOSSARY - Cartesian Coordinates (Site not responding. Last check: 2007-11-07)
		Cartesian coordinates (named after Descartes) are used to specify a point on a 2 dimensional surface by the horizontal distance and the vertical distance of the point from the horizontal and vertical zero reference points.
		Polar coordinates are used to specify a point on a 2 dimensional surface by its diagonal distance (radius) of the point from the horizontal and vertical zero reference points and the angle the diagonal would make with the horizontal (3 o'clock position).
		Coordinate Conversion is the conversion from Cartesian coordinates to Polar coordinates or vice versa as discussed in POLAR AND CARTESIAN COORDINATES.

		Cartesian coordinates[kArtE´zhun] Pronunciation Key [for RenE Descartes], system for representing the relative positions of points in a plane or in space.
		In a plane, the point P is specified by the pair of numbers (x,y) representing the distances of the point from two intersecting straight lines, referred to as the x-axis and the y-axis.
		In oblique coordinates the axes are not perpendicular; the abscissa of P is measured along a parallel to the x-axis, and the ordinate is measured along a parallel to the y-axis, but neither of these parallels is perpendicular to the other coordinate axis as in rectangular coordinates.

	Coordinates
		Coordinates are sets of numbers that describe position-- position along a line, on a surface or in space.
		Cartesian c oordinates (x,y) are not the only way of labeling a point P on a flat plane by a pair of numbers.
		In three dimensional space, the cartesian labeling (x,y,z) is nicely symmetric, but sometimes it is convenient to follow the style of polar coordinates and label distance and and direction separately.

		The most common coordinate system for representing positions in space is one based on three perpendicular spatial axes generally designated x, y, and z.

		Although the entire coordinate system can be rotated, the relationship between the axes is fixed in what is called a right-handed coordinate system.
