Cylindrical basis vectors
WebMar 23, 2024 · In my electromagnetism text (undergrad) there's the following statements for. position vectors in cylindrical coordinates: r → = ρ cos ϕ x ^ + ρ sin ϕ y ^ + z z ^. I understand this statement, it's the following, I don't understand how a 3D position can be expressed thusly: r → = ρ ρ ^ + z z ^. Thanks for any insight and help! Note: This page uses common physics notation for spherical coordinates, in which is the angle between the z axis and the radius vector connecting the origin to the point in question, while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use, and so care must be taken in comparing different sources.
