(10 marks) Let (1(8) 2 (021(3), 042(3), 0) and {3(3) 2 (0, 51(3), 52(8)) be unit speed simple closed curves in their respective planes, with a\"(s) 7E 0 for all .3. Let R = maxs{||(s)||} (which is necessarily a well-dened real number). Let T, N, B be the FYenet frame of a. Consider a function KW, v) = a(a) + N(U)/f31(v) + B(U)z(v)- Show that if $ > R for all s, then the image of x is a regular surface
