Abstract :We present the shape operator’s matrix of a surface along a surface curve. By using the obtained matrix, we give a short proof of the Beltrami-Enneper theorem. Also, we give a new method for  determining the well-known geodesic curves of a plane, a sphere and a circular cylinder by using  the relation between the ordinary curvatures of the geodesic and the curvatures of the surface.
Keywords : Shape operator, Darboux frame, curvature, geodesic curve
