Two points are antipodal (i.e., each is the antipode of the other) if they are diametrically opposite. Examples include endpoints of a
line segment, or poles of a sphere.
Given a point on a sphere with latitude 
and longitude 
, the antipodal point has latitude 
and longitude 
(where the sign is
taken so that the result is between 
and 
).
