text: As a one-dimensional complex manifold, the Riemann sphere can be described by two charts, both with domain equal to the complex number plane C. Let ζ be a complex number in one copy of C, and let ξ be a complex number in another copy of C. Identify each nonzero complex number ζ of the first C with the nonzero complex number 1/ξ of the second C.
