Coordinate system
Definition
A coordinate system is a framework for determining the position of points or vectors in space using numbers, typically defined by axes. Common types include Cartesian and polar coordinate systems.
5 Must Know Facts For Your Next Test
- The Cartesian coordinate system uses perpendicular axes (usually labeled x, y, and z) to define points in space.
- In a two-dimensional Cartesian coordinate system, any point can be represented as (x, y).
- The polar coordinate system represents points using a radius and angle from a reference direction.
- Vectors can be broken down into components along the axes of the chosen coordinate system.
- Transforming between different coordinate systems often involves trigonometric functions.

Cartesian Coordinate System: A coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines.
Polar Coordinate System: A two-dimensional coordinate system where each point on a plane is determined by an angle and a distance from a reference point.
