Some further analytical results on the solid angle subtended at a point by a circular disk using elliptic integrals
MetadataShow full item record
A series formulation involving complete elliptic integrals of the first and second kinds for the solid angle subtended at a point by a circular disk is presented. Results from the present model were tested against data sets obtained with previous treatments for the solid angle in order to determine the degree of simplicity and speed of our calculations. 3-D graphs are presented.
