Cylindrical Coordinate System - Definition

Definition

The three coordinates (ρ, φ, z) of a point P are defined as:

  • The radial distance ρ is the Euclidean distance from the z axis to the point P.
  • The azimuth φ is the angle between the reference direction on the chosen plane and the line from the origin to the projection of P on the plane.
  • The height z is the signed distance from the chosen plane to the point P.
