Sistema de Coordenadas Cartesianas
The Cartesian Coordinate System is a mathematical framework used to specify points in a two-dimensional or three-dimensional space. It consists of two or three perpendicular axes, typically labeled as the x-axis, y-axis, and z-axis. Each axis is associated with a valor numérico, called coordinates, which determine the position of a point relative to the origin. The origin is the point where all axes intersect, usually represented as (0,0) in 2D or (0,0,0) in 3D.
In a two-dimensional Cartesian coordinate system, any point can be expressed as an ordered pair (x, y), where ‘x’ indicates the horizontal position and ‘y’ represents the vertical position. For example, the point (3, 4) is located 3 units along the x-axis and 4 units along the y-axis from the origin.
In three-dimensional space, a point is represented by an ordered triplet (x, y, z). Here, ‘z’ indicates the depth or height of the point. This extension allows for a more comprehensive representation of objects and their locations in space, making it essential for applications in fields such as gráficos computacionais, robotics, and engineering.
O Sistema de Coordenadas Cartesianas é fundamental em mathematics and science, providing a clear and consistent method to visualize and analyze spatial relationships. It serves as the basis for various mathematical concepts, including geometry, algebra, and calculus.
