2. Cartesian coordinate system - Wikipedia

   en.wikipedia.org/wiki/Cartesian_coordinate_system

   A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system [8]) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis. The point where the axes meet is taken as the origin for both, thus turning ...

3. Analytic geometry - Wikipedia

   Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2,3) in green, (−3,1) in red, (−1.5,−2.5) in blue, and the origin (0,0) in purple. In analytic geometry, the plane is given a coordinate system, by which every point has a pair of real number coordinates.

4. Elementary mathematics - Wikipedia

   Usually the Cartesian coordinate system is applied to manipulate equations for planes, straight lines, and squares, often in two and sometimes in three dimensions. Geometrically, one studies the Euclidean plane (2 dimensions) and Euclidean space (3 dimensions). As taught in school books, analytic geometry can be explained more simply: it is ...

5. Coordinate system - Wikipedia

   en.wikipedia.org/wiki/Coordinate_system

   Another common coordinate system for the plane is the polar coordinate system. [7] A point is chosen as the pole and a ray from this point is taken as the polar axis. For a given angle θ, there is a single line through the pole whose angle with the polar axis is θ (measured counterclockwise from the axis to the line).

6. Line coordinates - Wikipedia

   en.wikipedia.org/wiki/Line_coordinates

   If points in the real projective plane are represented by homogeneous coordinates (x, y, z), the equation of the line is lx + my + nz = 0, provided (l, m, n) ≠ (0,0,0) . In particular, line coordinate (0, 0, 1) represents the line z = 0, which is the line at infinity in the projective plane.

   Foot Locker, Inc (NYSE:FL) stock tumbled in the premarket session on Tuesday. The company reported a third-quarter adjusted EPS of $0.33, missing the analyst consensus estimate of $0.41. Quarterly ...

8. Plane (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Plane_(mathematics)

   In mathematics, a plane is a two-dimensional space or flat surface that extends indefinitely. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. When working exclusively in two-dimensional Euclidean space, the definite article is used, so the Euclidean plane refers to the ...
