Math 407-500 Fall 2023
Test 2 Review
General Information
Test 1 will be given on Friday, 11/17/2023. Please bring an
8½×11 bluebook.
I will have office hours on Wednesday (11/15), Thursday (11/16), 12-1
and 2-3, and Friday (11/17) 12-1.
-
Calculators. You may use calculators to do arithmetic, although
you will not need them. You may not use any calculator that
has the capability of doing linear algebra or storing programs or
other material.
-
Other devices. You may not use cell phones, computers, or any
other device capable of storing, sending, or receiving information.
-
Structure and coverage. There will be 4 to 6 questions, some
with multiple parts. In what follows, SO stands for Schaum's Outline
and BC for Brown/Churchill. The test will cover SO, chapter 4 and
chapter 5, 5.1-5.6; BC, chapter 5, sections 57-62 (pgs. 189-207).
The problems will be similar to ones done for
homework, and as examples in class and in the texts. There will
also be questions about definitions, and statements and proofs of
theorems. These are indicated below.
Topics Covered
Line and Contour Integrals
- Line integrals. Know the definition of a line integral, real and
complex (SO 4.2,4.3), how to parameterize a curve, definition of a
simple closed curve, a simply connected region and a multiply
connected region (SO 4.6-4.8), know and be able to use Green's
Theorem.
- Be able to state Cauchy's Theorem. Be able to use Green's Theorem
and the Cauchy-Riemann conditions to prove it for a simply connected
region (SO 4.11). Know its statement for a multiply connected region
(SO 4.15, Theorems 4.4 and 4.5). See the homework problems for
Assignment 4.
Cauchy's Integral Formulas and Related Theorems
- Know the Cauchy's Integral formulas (SO 5.1) and be able to use
them to compute various contour integrals (see Assignment 5).
- In SO 5,2, be able to state theorems 2-7, and be able to prove
Cauchy's Inequality (theorems 2) and Liouville's Theorem (theorem 3).
Taylor and Laurent Series
- Be able to state Taylor's Theorem and be able to use the fact
that the power series for a function is the Taylor series for a given
analytic function $f(z)$ (see assignment 6). Be able to state the
circle where the Taylor series converges to the given function. (See
class notes for Nov. 8)
- Be able to state Laurent's Theorem and be able to use the fact
that the Laurent series for a function $f(z)$ is unique, no matter how
it is obtained. Know that a function may have different Laurent series
in different annuli about a given point $z_0$. (See class notes for
Nov. 13 and problems in Assignment 7.)
