Spherical coordinates
(r, theta, phi)
involve one length coordinater
and two angle coordinatestheta
andphi
, one representing longitude and varying in a length2*pi
interval, typically[0, 2*pi]
, the other representing latitude and varying in a lengthpi
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

method using pole-based latitude. Providing equator-based latitude would be a nice option.Besides, the order of the angular coordinates could be customized.
