The spherical coordinates of a given system are denoted by the coordinate (r, θ, Φ). In such a system the coordinates are commonly addressed as an ordered pair and symbolised as (x, y) in the two-dimensional plane and (x, y, z) in the three-dimensional plane.įor the (x, y), x denotes the x-coordinate and y denotes the y-coordinate that are marked on the horizontal and the vertical axis respectively.Īlso, read about the x-axis and y-axis here. It is the most commonly used coordinate system. The system that is used to mark points in a plane is understood as the cartesian system. Let us read about these coordinates as well. The common types of coordinates in analytical geometry are as follows The coordinates x and y can be positive, negative, or zero depending on the location of the point in the respective quadrants(I, II, III or IV). Here the x value is the status of the point concerning the x-axis, and the y value is the status of the point concerning the y-axis. Any point in the coordinate plane is directed in the format (x, y). The coordinates in the coordinate plane are a set of two points/values that locate an exact point on the 2D face. The division of the cartesian plane helps locate the points in space. Learn more about the General Equation of a Line. These two axes (the x-axis and y-axis) divide the cartesian plane into four quadrants as shown below. The two axes intersect each other at a point named the origin. The two lines are named the horizontal line or the X-axis and the vertical lines or the Y-axis. Let us learn more about the coordinate planes and their coordinatesĪ coordinate plane divides a two-dimensional plane via two lines. Thus it is also known as coordinate geometry or cartesian geometry. Coordinate PlaneĪs of now, we can say that analytic geometry uses the concepts of algebra to locate the position of the point on the plane utilising an ordered pair of numbers called coordinates. For example the distance between points, equations of a line and curves, slopes of lines, midpoints, etc. By representing every point with a certain set of real numbers, different geometric figures like lines, circles, as well as conics can be defined with algebraic equations.Īlso, particular elements of geometry can be very efficiently addressed in the coordinate plane. Herein, different geometric shapes are represented using algebraic equations in a two-dimensional or three-dimensional space.
In other words, the use of a coordinate system to connect geometric points to real numbers is the foremost concept of analytic geometry. In analytic geometry different algebraic equations are used to describe the dimensions and position of different geometric figures. That is it is the analysis of geometry on a grid named the coordinate plane. Analytical geometry can be understood as a combination of geometry and algebra. In this particular article, you will learn what analytic geometry is, all related terms, formulas, equations and much more.
