Index Entry
… Spherical trigonometry is a very different kind of trigonometry from the plane. I want you to get familiar with it because there is no plane flat surface on Earth. So therfore there are no plane triangles and we are always dealing in systems. Systems are characterized by triangles which are spherical triangles. “These are the kinds of triangles which control our fundamental transformations.”
