Description (last modified by )
Spherical coordinates (r, theta, phi)
involve
one length coordinate r
and two angle
coordinates theta
and phi
, one representing
longitude and varying in a length 2*pi
interval,
typically [0, 2*pi]
, the other representing
latitude and varying in a length pi
interval:
either [0, pi]
if the latitude is measured
from one of the poles, or [-pi/2, pi/2]
if the latitude is measured from the equator.
Sage's euclidean space has a spherical_coordinates
method using pole-based latitude. Providing
equator-based latitude would be a nice option.
Besides, the order of the angular coordinates could be customized.
