| Abstract: | In this paper the author gives the coefficients of connection of a curved surface when orthogonal grid is taken as a parameter orthogonal grid of curved surface S, and finally the author gives the computation of the coefficients of connection and that are expressed by the coefficients E, F, G, which are coefficients of the primary elemental form of a surface, and their partial differentials. |
