Hi. Please help explain a solution to this problem. It is about Geometry On A Sphere. Some GR or differential geometry can be helpful. Your help is highly appreciated.Suppose you are a two-dimensional being, living on the surface of a sphere with radius R. An object of width ds * R is at a distance r from you (remember, all distances are measured on the surface of the sphere). What angular width d? will you measure for the object? Explain the behavior of (169 as Y-> ?R
