Take the tour ×  What is the higher dimensional analogue for the
arc of a circle?  I'd like to work with the set of all points
lying within a certain distance of a given point on an n-sphere,
and I'd like to describe these sets by the (generalised) solid
angles which they subtend.  share|improve this question A
spherical wedge, or a spherical cap? –  Ｊ. Ｍ. Aug 1 '12 at 2:33
Or hyperspherical, as the case may be. It's easy to denote it as
an intersection of a ball and a sphere. –  anon Aug 1 '12 at

vote accepted  By request:  It seems you want either the
spherical cap or the spherical wedge, or hyperspherical versions
thereof.  share|improve this answer Thanks, just what I was
looking for. Thanks also to anon. –  grain.man Aug 1 '12 at 3:10
