Math 3574: Applied Complex Variables
On line delivery
This class will be delivered on-line. As far as possible, the course will
be self-paced. Students taking this class will need well-developed independent
learning skills to succeed. Students wishing to learn the same material in a
more traditional setting should take MATH 4574 or MATH 4234
The course is intended to cover most of the material on complex variables usually
covered in MATH 4574. There are four "modules" covered.
- Basics of Complex Numbers
- Basic Components of Complex Numbers
- Arithmetic of Complex Numbers
- Complex Conjugate
- The Geometry of Complex Numbers
- The representation of complex numbers in polar coordinates
- Geometry of the basic arithmetic operations of complex numbers
- Geometry of exponentiation
- Geometry of roots
- Elementary Functions of a Complex Variable
- Complex exponentials
- Complex trig functions
- Complex hyperbolic functions
- Logarithmic functions
- Powers of complex numbers
- Properties of Complex Functions
- Sets in the Complex Plane
- Limits and Continuiuty
- Analytic and Harmonic Functions
The text for the course is available as a .pdf
file. Please download it and print it out.
Students may find that a text such as Advanced Engineering Mathematics
by P.V. O'Niel is helpful in supplementing on-line materials. (This text
is often used in Virginia Tech's Math 4574 course. It contains a great deal
of material in addition to the sections on complex variables.)
On line quizzes and tests
- Some general advice on using the online testing system can be found here.
These are general instructions for using the testing system. Not all items
mentioned apply to this class.
- There is a collection of short Practice Quizzes that can
be taken from any computer. The practice quizzes are available here.
(Click the Quiz and Test System button near the bottom of that page.)
The questions in these quizzes will be randomly selected from the question
database for the appropriate module. By taking thes Practice Quizzes several
times, you should be able to get an idea of all of the types of questions
to appear on the module tests.
- The Module tests (which are used to determine your grade) are refered to
as Poctored Exams in the on line testing system. These must
be taken at the Math Emporium. See the Emporium
web page for hours when testing is available. You will need your Hokie
passport and must know your PID and password.
- You will be able to review any previously taken test at
any time. Feel free to discuss previously taken test with other students or
WARNING: While the on line testing system
has been working well, but there still may be technical glitches or errors in
the question database. If you are unable to read a question or feel that the
question is in error, please write down the time, the number of the question,
and problem. Point this out to the proctor, note the name of the proctor and
send me an email with the information.
The course grade will be based on the four proctored online module tests. Each
test will be given equal weight. Each test has 20 points for a total of 80 points
for the course. Grades will be assigned as follows
Students may take each proctored test as many times as they wish (versions
will be generated on line) and will receive credit for the highest grade received.
Tests may be taken whenever the student is ready, subject to availability.
Note: It is our intention that you teach yourself this material by taking
the tests repeatedly. You are encouraged to take the test often. In particular,
it is good practice to take the online quizzes or even a proctored test before
reading the section.
- The Undergraduate Honor Code pledge that each member of the university
community agrees to abide by states:
Students enrolled in this course are responsible for abiding by the Honor Code.
A student who has doubts about how the Honor Code applies to any assignment is
responsible for obtaining specific guidance from the course instructor before
submitting the assignment for evaluation. Ignorance of the rules does not
exclude any member of the University community from the requirements and
expectations of the Honor Code.
- As a Hokie, I will conduct myself with honor and integrity
at all times. I will not lie, cheat, or steal, nor will I accept the
actions of those who do.
- For additional information about the Honor Code, please visit: https://www.honorsystem.vt.edu/
- Students must abide by the testing and proctoring procedures available at
the Math Emporium while taking module tests. Students may discuss tests they
have taken with anyone. (Each instance of a test will be different.)
