3D Cartesian coördinates, also known as rectangular coordinates, are a system of describing the position of a point in three-dimensional space using three numbers representing the distances from three perpendicular axes.
3D Cartesian coördinates include a third axis, typically represented by the letter "z", in addition to the x and y axes used in 2D Cartesian coördinates. This allows for the representation of points in three-dimensional space, rather than just on a flat plane.
The three axes used in 3D Cartesian coördinates are the x-axis, y-axis, and z-axis. These axes are perpendicular to each other, forming a right-handed coordinate system.
In 3D Cartesian coördinates, points are represented by an ordered triple (x, y, z), where x represents the distance along the x-axis, y represents the distance along the y-axis, and z represents the distance along the z-axis. This is also known as the (x, y, z) coordinate of the point.
3D Cartesian coördinates are commonly used in mathematics and science to describe the position of objects in three-dimensional space. This is useful in fields such as physics, engineering, and computer graphics, where understanding the spatial relationships between objects is important.
