Problem 3. Earlier this semester, we proved the Fundamental Theorem of Algebra using an application of Liouville's Theorem. This problem asks you to fill in the details of an alternate proof of the Fundamental Theorem of Algebra that uses Rouché's Theorem. Let p(2) = 20 + 01 + a222 + ... + an-12"-1+ anza be a nonconstant polynomial of degree n > 1. (a) First, we choose R large enough so that, if |:| = R, then ao +213 +222+...+an-12"-1...

An important fact we have proved is that the family (enr)nez is orthonormal in L (T,C) and complete, in the sense that the Fourier series of f converges to f in the L2-norm. In this exercise, we consider another family possessing these same properties. On [-1, 1], define dn Ln)-1) 0, 1,2, Then Lv is a polynomial of degree n which is called the n-th Legendre polynomial. (a) Show that if f is indefinitely differentiable on [-1,1], thern In particular,...

PROJECT 6.2 In this project you will construct an increasing function that is discontinuous at each rational point in (0, 1) and continuous at each irrational point in (0, 1). We will need two basic facts: a. The rational numbers in the interval (0, 1) can be arranged in a sequence rThis is true because the set of rational numbers is countable. (See Example 0.12 and Corollary 0.15.) b. Any rearrangement of an absolutely convergent series converges, and any sub-...

6. We want to use the Integral Test to show that the positive series a converges. All of the following need to be done except one. Which is the one we don't need to do? (a) Find a function f(x) defined on [1,00) such that f(x) > 0, f(x) is decreasing, and f(n) = a, for all n. (b) Show that ſ f(z) dr converges. (e) Show that lim Ss6 f(x) dx exists. (d) Show that lim sexists. 7. Suppose...

1. PRELIMINARY DISCUSSION 1.1. Goal. The goal of this assignment is to use Green's Theorem and line integrals to prove the following theorem. Theorem 1. Let S denote the closed unit ball in R2, that is, S := {x E R2 : 1-1 Assume that F : S → R2 is a function of class C2 such that F(x) = x for all x E as. Then it cannot...

Limits and Continuity 4 Chapter Remark: In the statement of Theorem 4.4.12 we assumed that f was tone and continuous on the interval I. The fact that f is either stric tric. strictly decreasing on / implies that f is one-to-one on t one-to-one and continuous on an interval 1, then as a consequence of the value theorem the function f is strictly monotone on I (Exercise 15). This false if either f is...
