Problem 19*
Consider the surface R², given by r(u, v) = (u, v).
(a) Compute E, F and G. Verify that the matrix form of g is given by
[du]
(b) Let v = Show that |v||2 = g(v, v) = du² + dv².
dv
(c) Verify that ds = dA.
(1)
Therefore, with the metric as in part (a), on R², everything reduces to our usual working condition
i.e., Euclidean setting. The matrix given in part (a) is the Euclidean metric, which is an example of a
Riemannian metric on R².
