| 31. | :: : You use spherical coordinates or a related system, which is basically what you are describing.
|
| 32. | For example, the equations in this article can be used to write Maxwell's equations in spherical coordinates.
|
| 33. | In addition to the above measures, to calculate prayer times for a specific location we need its spherical coordinates.
|
| 34. | That step is invalid in spherical coordinates, because subtracting vectors in spherical coordinates just does not work that way.
|
| 35. | That step is invalid in spherical coordinates, because subtracting vectors in spherical coordinates just does not work that way.
|
| 36. | Here, we have assumed a spherical coordinate system in which the-axis is aligned with the beam direction.
|
| 37. | I will introduce a set of spherical coordinates and define a function F ( ?, ? ) on it.
|
| 38. | Spherical coordinates as often used in " mathematics " : radial distance, azimuthal angle, and polar angle.
|
| 39. | In particular, it occurs when solving Laplace's equation ( and related partial differential equations ) in spherical coordinates.
|
| 40. | I may be mistaken, but would you be trying to find the angle between two vectors given in spherical coordinates?
