Coordinate Geometry

Coordinate Geometry

1. DISCOVERY

   • It was discovered by Rene Descartes, a French mathematician. He discovered it in the seventeenth century. It is in his honour that, the plane is known as Cartesian Plane.
   • DISCOVERED BY A FRENCH MATHEMATICIAN RENE DESCARTES IN THE SEVENTEENTH CENTURY
   • IT IS IN HIS HONOR THAT THE PLANE WHICH IS DESCRIBED AS THE GRAPH IS NAMED AS THE CARTESIAN SYSTEM

2. PRACTICAL USE

   • GRAPH
     • X-AXIS
       • It is the latitude of the graph of the plane. It extends from a positive to negative dimension. 
       • IT IS THE LATITUDE OF THE GRAPH OF THE PLANE
       • IT EXTENDS FROM THE POSITIVE TO THE NEGATIVE AXIS
     • Y-AXIS
       • IT IS THE LONGITUDE OF THE GRAPH OF THE PLANE
       • IT EXTENDS FROM THE POSITIVE TO THE NEGATIVE AXIS.
     • ORIGIN
       • POINT OF INTERSECTION OF THE TWO AXES.
       • COORDINATES = (0.0)
     • QUADARNTS
       • THE TWO AXES DIVIDE THE PLANE INTO FOUR QUADRANTS OR PARTS.
         • FIRST QUADRANT COORDINATES: +X,+Y
         • SECOND QUADRANT COORDINATES: -X,+Y
         • THIRD QUADRANT COORDINATES: -X,-Y
         • FOURTH QUADRANT COORDINATES: +X,-Y
     • COORDINATES
       • IT IS A SET OF TWO VALUES WHICH REPRESENTS THE INTERSECTION OF THE X-AXIS AND THE Y-AXIS IN THE PLANE.
   • IT IS USED TO DETERMINE THE EXACT POSITION OF ANY OBJECT ON A PLANE
   • IT IS A KIND OF WAY TO REPRESENT NUMBERS LIKE THE NUMBER LINE.
