1. Prove that A R n is measurable if and only if A = G \ Z for some G δ -set 1 and some set Z of measure 0 . 2. Show that the inverse function theorem follows from the implicit function theorem. 3. Suppose that U R n is open and that f : U R has continuous second-order partial derivatives on some ball B r ( a ) for some a U , and that f ( a ) = ~ 0 . Suppose that the Hessian of f at a has both positive and negative eigenvalues. Use Taylor’s theorem to prove that f has a saddle point at a . 4. Recall that a point x R is a condensation point of a set A if every neighborhood of x contains uncountably many points in A
