Cartesian coordinate system
A system in which the location of a point is given by coordinates that represent its distances from perpendicular lines that intersect at a point called the origin. A Cartesian coordinate system in a plane has two perpendicular lines (the x-axis and y-axis); in three-dimensional space, it has three (the x-axis, y-axis, and z-axis). Compare polar coordinate system.
Usually, Cartesian coordinates. a member of a system of coordinates for locating a point on a plane (Cartesian plane) by its distance from each of two intersecting lines, or in space by its distance from each of three planes intersecting at a point.
a glass vessel partially filled with water and covered with an airtight membrane, containing a hollow object that is open at the bottom and contains just enough air to allow it to float. Pressing on the membrane compresses the air in the vessel and forces water into the object, causing it to sink; releasing the […]
willful suspension of all interpretations of experience that are not absolutely certain: used as a method of deriving, by elimination of such uncertainties, axioms upon which to base theories.
the collection of all ordered pairs of two given sets such that the first elements of the pairs are chosen from one set and the second elements from the other set: this procedure generalizes to an infinite number of sets. noun (maths, logic) the set of all ordered pairs of members of two given sets.
