These choices determine a reference plane that contains the origin and is perpendicular to the zenith. The spherical coordinates of a point P are then defined as follows: • The radius or radial distance is the Euclidean distance from the origin O to P. shoney\u0027s nashville tennessee

"Web1. aug 2024 · Well, consider at a point $ (r, \theta, \phi)$, we move a tiny bit in the local $\hat {\boldsymbol\phi}$ direction, which amounts to a $\delta\phi$ rotation about the $z$ axis. The tip of the $\hat {\mathbf r}$ vector will have also rotated after this rotation. " - Phi hat direction
