2. Bracket (mathematics) - Wikipedia

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

   In the Cartesian coordinate system, brackets are used to specify the coordinates of a point. For example, (2,3) denotes the point with x -coordinate 2 and y -coordinate 3. The inner product of two vectors is commonly written as a , b {\displaystyle \langle a,b\rangle } , but the notation ( a , b ) is also used.

3. 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 ...

4. Coordinate system - Wikipedia

   en.wikipedia.org/wiki/Coordinate_system

   The coordinates are taken to be real numbers in elementary mathematics, but may be complex numbers or elements of a more abstract system such as a commutative ring. The use of a coordinate system allows problems in geometry to be translated into problems about numbers and vice versa; this is the basis of analytic geometry. [3]

5. Abscissa and ordinate - Wikipedia

   en.wikipedia.org/wiki/Abscissa_and_ordinate

   For any point, the abscissa is the first value (x coordinate), and the ordinate is the second value (y coordinate). In mathematics, the abscissa (/ æ b ˈ s ɪ s. ə /; plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system: [1] [2]

6. Analytic geometry - Wikipedia

   en.wikipedia.org/wiki/Analytic_geometry

   In mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry . Analytic geometry is used in physics and engineering , and also in aviation , rocketry , space science , and spaceflight .
