Solid Angle
Defined as the Surface Area 
of a Unit Sphere which is subtended by a given object 
. Writing theSpherical Coordinates as 
for the Colatitude (angle from the pole) and 
for theLongitude (azimuth),
Solid angle is measured in Steradians, and the solid angle corresponding to all ofspace being subtended is
Steradians.See also Sphere, Steradian- Minimal Matrix
