| 释义 | > as lemmasCartesian co-ordinates In the original (and most often used) system, invented by Descartes, and hence known as that of Cartesian co-ordinates, the co-ordinates of a point (in a plane) are its distances from two fixed intersecting straight lines (the axes of co-ordinates), the distance from each axis being measured in a direction parallel to the other axis. (The determination of the position of a place by latitude and longitude is a similar case.) The co-ordinates are rectangular when the axes are at right angles; otherwise oblique. The name Cartesian co-ordinates is also extended to the case of points in space (not in a particular plane) referred to three axes not in one plane intersecting in a point (like three edges of a box meeting at one corner).extracted from co-ordinateadj.n.< as lemmas |
