2. (a) For 0<u< 2 and 0 < v< 2л, let σ(u, v) = (u, v) be the part of xy-plane.
Determine the Gauss curvature, say Kp, of the given surface P.
(b) For 0<u<2 and 0 < v<2π, let 8(u, v) be the part of a cylinder. Write
down the parametrization of 8(u, v) and determine the Gauss curvature, say
Kc, of the given cylinder C.
(c) Write down the definition of local isometry.
(d) Show that the given plane P and the given cylinder C are local isometric to
each other.
(e) Show that Theorem 10.2.1 (Gauss' Theorema Egregium) holds for the given
plane P and the given cylinder C.
