A plane
A plane in mathematics is a two-dimensional flat surface that extends infinitely in all directions
A plane in mathematics is a two-dimensional flat surface that extends infinitely in all directions. It is often represented as a piece of paper or a tabletop. In a plane, there are no boundaries or edges, and any two points on the plane can be connected by a straight line.
Similar to a coordinate system, a plane can be identified using a coordinate system called the Cartesian plane. It consists of two perpendicular lines known as the x-axis and the y-axis. The point where the two axes intersect is called the origin, often denoted as (0,0). Any point on the plane can be located using its coordinates, where the x-coordinate denotes the horizontal position and the y-coordinate denotes the vertical position of the point.
In the Cartesian plane, each point is represented by an ordered pair (x, y), where x is the distance from the y-axis and y is the distance from the x-axis. For example, the point (3, 5) represents a point that is three units to the right of the y-axis and five units above the x-axis.
Planes play a significant role in various mathematical concepts, such as geometry, linear algebra, and calculus. They can be used to analyze and solve problems involving lines, shapes, and transformations in space.
