... The basis vectors are a set orthonormal vectors pointing in the directions of increasing coordinate values. With three coordinates, say (r, θ, φ), there are three corresponding basis vectors (~er , ~eθ , ~eφ ). This definition applies, of course, to the Cartesian basis vectors as well. What distingu ...
