-A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length. Cartesian coordinate system is a way of locating objects in either two- or three-dimensional space by specifying their X(horizontal) position, Y (vertical) position and Z (through) position. It is used in graphics and in positioning text on documents.

-Algebraic equations involving the coordinates of the points lying on the shape. For example, a circle o f radius 2 may be described as the set of all points whose coordinates x and y satisfy the equation x2 + y2 = 4.

A system or two or three mutually perpendicular axes along which any point can be precisely located with reference to any other point, often referred to as x, y and z coordinates. Relative measure of distance, area and direction are constant throughout the system. The Cartesian coordinate system is named after René Descartes.

The idea of this system was developed in 1637 in two writings by Descartes and independently by Pierre de Fermat, although Fermat used three dimensions, and did not publish the discovery.
Two dimensions

In two dimensions the position of a point P in a plane can be specified by it's distance from two lines intersecting at right angles, called axes. For instance, in Figure 1 two lines intersect each other at right angles in the point 0, the origin. One axis is the line O-X, the other O-Y and any point in the plane can be denoted by two numbers giving it's perpendicular distances from O-X and from O-Y.

A general point P can reached by traveling a distance x along a line O-X, and then a distance y along a line parallel to O-Y. O-X is called the x-axis, O-Y the y-axis, and the point P is said to have Cartesian coordinates (x, y). In the coordinate system shown, as is indicated in the diagram, the...

..."Cartesian" is named after the French mathematician and philosopher Rene Descartes, who lived from 1596 until 1650. Cartesian diver lab is used commonly in scientific experiments to illustrate principle of buoyancy. The objective of this Cartesian diver lab is to demonstrate Pascal's law and Archimedes' principles.
Observation is the key to conduct this experimental study of the Cartesian diver. First a 2-liter bottle is filled with...

...Cartesian Diver
The purpose of the Cartesian diver is to demonstrate the compressibility of a gas, the incompressibility of water, Boyle's law, Pascal's law, and Archimedes' law. Boyle's Law states that under conditions of constant temperature and quantity, there is an inverse relationship between the volume and pressure for an ideal gas. Pascal's Law states that if pressure is applied to a non-flowing fluid in a container, then that pressure is transmitted...

...generalized three-dimensional analytical solution is developed for a partially-penetrating vertical rectangular parallelepiped well screen in a confined aquifer by solving the three-dimensional transient ground water flow differential equation in x-y-z Cartesian coordinates system for drawdown by taking into account the three principal hydraulic conductivities (K _x, K _y, and K _z) along the x-y-z coordinate directions. The fully penetrating screen case becomes equivalent to...

Cartesian Compromise:
Bridging Psyche and Soma
Introduction
In 1995, Blaine M. Yorgason published the true story of his adopted daughter, Charity. One Tattered Angel captures the Mind/Body Problem, proclaiming the existence of the spirit (mind) and challenging the connection to the body. On August 31, 1988 the Yorgason family was asked...

...Cartesian Method
A.) Cartesian doubt
Cartesian doubt is a form of methodological skepticism associated with the writings and methodology of René Descartes. Cartesian doubt is also known as Cartesian skepticism, methodic doubt, methodological skepticism, or hyperbolic doubt.
Cartesian doubt is a systematic process of being skeptical about (or doubting) the truth of one's beliefs, which has become a...

...* The Role of Feeling (Hutcheson)
* Hutcheson goes on to argue in length that reason isn’t enough to explain moral judgment
* Reasons motivate action insofar as certain ends (goals; happiness) are an object of human “affections” such as self–love or benevolence (desire for our own or others’ happiness)
* The end of promoting the public interest gives us a reason for action or approbation only insofar as we have a “moral sense” that makes us take pleasure in the character...

...Descartes’ Cartesian Circle
Descartes’ “Cartesian Circle” has come under fire from countless philosophers because it supposedly commits a logical fallacy with its circular reasoning. In his second Meditation, Descartes attempts to prove the existence of God. He states that clear and distinct perception leads to knowledge, and that God’s existence is apparent and obvious because of things we have come to perceive as knowledge. Furthermore, he asserts that we...

...CARTESIAN DUALISM
Rene Descartes, a sixteenth century philosopher and mathematician, attempted to address the issue of how the mind and body interact which subsequently proposed the theory of Cartesian Dualism. According to Descartes, Cartesian Dualism is the belief that mental states are states of an immaterial substance that interacts with the body. He articulates and supports this theory by using the conceivability argument...
