高中《立体几何》在定义两点间的球面距离之前有一个未加证明的结论:“在球面上,两点之间的最短距离是经过两点的大圆在这两点间的一段劣弧的长度.”我经过反复思索得到这个结论的一种证明方法,现提供出来与同学们共同探讨并敬请老师们指正.
The high school “Solid Geometry” has an unproven conclusion before defining the spherical distance between two points: “On the sphere, the shortest distance between two points is a bad arc between the two points after a big circle passing through two points. Length. ”A method of proof that I have come up with after repeated consideration to obtain this conclusion is now available to discuss with my classmates and ask the teachers to correct me.
