Determinning the Critical Point and the Equator Crossing of a Geodesic

In this paper,the two special points of a geodesic is described:The critical point and the equator crossing are defined by some special terms respectively.The positions of the critical point and the equator crossing of a geodesic are determined with the nested coefficient method.Finally the accuracies of the positions are shown by some prectical examples computed.
