History: The Cartesian coordinate system is named after René Descartes(1596-1650)‚ the noted French mathematician and philosopher‚ who was among the first to describe its properties. However‚ historical evidence shows that Pierre de Fermat (1601-1665)‚ also a French mathematician and scholar‚ did more to develop the Cartesian system than did Descartes. The development of the Cartesian coordinate system enabled the development of perspective and projective geometry. It would later play an intrinsic

Cartesian Coordinate System -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

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 the single vertical fracture case of Gringarten and Ramey (1973). It is shown that the new solution and

Homogeneous Coordinates and Matrix Representation Homogeneous Coordinates Homogenous coordinates utilize a mathematical trick to embed three-dimensional coordinates and transformations into a four-dimensional matrix format. As a result‚ inversions or combinations of linear transformations are simplified to inversion or multiplication of the corresponding matrices. Homogenous coordinates also make it possible to define perspective transformations. Homogenous coordinates allow each point

(b) the Earth revolves around the Sun. (c) the tilt of the Earth’s axis changes. (d) their right ascensions constantly change. (e) their declinations constantly change. 2.

René Descartes René Descartes has been dubbed the "Father of Modern Philosophy"‚ but he was also one of the key figures in the Scientific Revolution of the 17th Century‚ and is sometimes considered the first of the modern school of mathematics. As a young man‚ he found employment for a time as a soldier (essentially as a mercenary in the pay of various forces‚ both Catholic and Protestant). But‚ after a series of dreams or visions‚ and after meeting the Dutch philosopher and scientist Isaac Beeckman
