Hi,

How is it possible to compute this:
a spherical triangle is given by its three sides (three angles between
the three vectors). Somewhere in the triangle lies the origin (North
pole). From two of the points of the triangle, we know the distance
(angle between vector to point and North pole) to the North pole. How
can one computes the distance (angle) to the third point?
The coordindates of the points are not given.

Thanks,

S. Nurbe
