球面直角四面体的体积公式(英文)

The volume formula of rectangular spherical tetrahedrons

诱导了在三维单位球S3(1) 上的球面直角四面体的体积公式。

In this paper,we shall introduce the volume formula of the spherical tetrahedron in S 3(1) from the study of spherical trigonometry on S 2(1) and compute the volume of the decomposed rectangular spherical tetrahedron.
