WebSpherical polygons. A spherical polygon is a polygon on the surface of the sphere. Its sides are arcs of great circles—the spherical geometry equivalent of line segments in plane geometry.. Such polygons may have any number of sides greater than 1. Two-sided spherical polygons—lunes, also called digons or bi-angles—are bounded by two great … WebAug 26, 2024 · (The reason I did not do this in spherical coordinates is that I need to find the "start" and "end" points of the circle in the independent variable and with $\sin$ and $\cos$ corresponding to more than one possible angle, this might be ambiguous.) I think so far this should be correct. southwell minster bookshop https://langhosp.org
