Consider the line element of the sphere of radius a: ds²a² (do²+ sin² 0 do ²). The only non-vanishing Christoffel symbols are го = - sin 0 cos 0, ФФ ГР = rø ГФ00 = ГФ = 2.900 a) Write down the metric and the inverse metric, and use the definition 1 to reproduce the results written above for rº (8μgvo + avguo dogur) = rº vp - ΦΘ and r op = 00* 1 tan 0 b) Write down the two components of the geodesic equation. c) The geodesics of the sphere are great circles. Thinking of 0 = 0 as the North pole and = π as the South pole, find a set a solutions to the geodesic equation corresponding to meridians, and also the solution corresponding to the equator.
