6. For any positive number k, an immersion z: MC² defined by
x(u, v) = (u, k cos u, v, k sin v).
Then:
(i) Show that M is a slant surface in C².
(ii) Find the slant angle of A.
(iii) Find the second fundamental form corresponding to each vector field i.e., h(e, ej), 1≤
i, j≤ 2.
(iv) Find the constant mean curvature of M.
(y) Show that M is neither totally geodesic (i.e., h 0 for at least some e,, ej, 1 ≤
i, j≤2) nor minimal (i.e., H # 0) submanifold.
