(b) Fix a positive number [ε. Does converges to f(x) unifornly over [ε, ∞)? Give your reason.

(4) [20 分] Let F be a smooth map from R3 to R3. Denote by (x1, x2, x3) the coordinate for the domain R3. Denote the origin (0,0,0) by 0. Suppose that Prove that there exist ●open neighborhoodsof O in (the domain) R3, and a diffeomorphism φ :which maps O to O, ●open neighborhoodsof O in (the target) R3, and a diffeomorphism V which maps O to O, What follows is the diagram for your reference.
