X coordinate – The X-coordinate of a point is the distance from origin to foot of perpendicular on X-axis. Coordinates of a Point ( or) Locating of coordinate pointsĪ quadrant also defined as a part of a cartesian or coordinate plane obtained when the two axes intersect each other. These four parts are called the quadrants and are denoted by Quadrant -1 (Q1), Quadrant -2(Q2), Quadrant -3(Q3) & Quadrant -4( Q4) in anti clockwise direction. The coordinate plane is divided into four parts by these coordinate axes. The X & Y axes are known as coordinate axes. The plane here is known as the cartesian plane or co-ordinate plane or XY-plane. Also the negative numbers lie on the directions OX 1 is called the negative directions of the X-axis, similarly OY 1 is the negative Y-axis respectively. In this plane the positive numbers lie on the directions OX is called the positive direction of the X-axis, similarly OY is the positive Y-axis respectively. The point where XX 1 & YY 1 intersecting each other is called the origin, and is denoted by ‘O’. The horizontal number line XX 1 is known as X-axis and the vertical number line YY 1 is known as Y-axis. The intersection point is denoted as origin.
In the above figure we draw a vertical number line and horizontal number line meeting at a point perpendicular to each other. He is a French mathematician and philosopher and he is established an association between algebraic equations and geometric curves and figures.
The concepts of Co-ordinate Geometry were developed by Rene Descartes (1596-1650). Coordinate Geometry is one of the new branch of mathematics to representation of a point on a plane with idea of two references. 1.2 Summary of Coordinates Geometry IntroductionĬoordinate geometry is one of the important concept in mathematics.1.1 Coordinates of a Point ( or) Locating of coordinate points.1 Basic Concepts of Coordinate geometry.
