| Spherical | A coordinate representation of a positionvector or of a measured vector by its magnitude and two direction angles.The angles are relative to the base axes of the coordinate system used.Typically the a ngles are phi [azimuth angle, =arctan (j/i)] and theta, wheretheta may be a polar angle, arctan {[SQRT(i^2+j^2)]/k}, or an elevationangle, arctan [k/SQRT (i^2+j^2)]. | Ryan McGranaghan | 2023.04.16 |
