Example Sentences
- "1974 [Prentice-Hall], Richard A. Silverman, Complex Analysis with Applications, Dover, 1984, Unaltered republication, page 19, Thus we see that stereographic projection establishes a one-to-one correspondence between the extended complex plane and the Riemann sphere."
- "1991, E. J. F. Primrose (translator), Simeon Ivanov (editor of translation), A. T. Fomenko, A. A. Tuzhilin, Elements of the Geometry and Topology of Minimal Surfaces in Three-Dimensional Space, American Mathematical Society, page 67, Proposition 2. The stereographic projection π_N:S²→Oxy of the sphere S² onto the xy-plane from the North Pole N preserves the angles between tangent vectors. Thus, the coordinates specified on S²⧵N by the stereographic projection π_N are isothermal."
- "Before we can recognize such patterns confidently, we need to know whether the stereographic projection faithfully represents the true clustering of directions in space."
