Ordinary differential equations and Green's functions;
partial differential equations and separation of variables; special functions,
Fourier series. Applications to engineering and
science. Not for credit by mathematics majors.
Goals:
Upon successfully completing this course,
·
You will be skilled in solving the fundamental
linear PDE's that engineers use.
·
You will be familiar with the properties of the
heat/diffusion equation, the wave equation, and the potential/Laplace equation.
·
You will be able to find series and integral
solutions to these PDE, in Cartesian and/or polar coordinates.
·
You will be able to display solution curves and
surfaces in space and time on the computer.
·
You will be able to use and implement different
kinds of boundary conditions.
MA 501
versus 401: These two courses are almost identical. I teach both of them.
However, I expect more from my students at the 500 level, so we cover more
topics in the same amount of time. In particular, we cover integral transforms
in 501 but not in 401.
Required Text: Partial Differential Equations with Fourier Series
and Boundary Value Problems, 2nd edition, by Nakhle Asmar. The text is on
reserve in the library but you should own your own copy. There is an online
Student Solutions Manual with most of the odd-numbered problems worked out, at
Nakhle Asmar's home page. It also contains a list of errata from the early
printings of the book.
Possible supplements: Some people like using Schaum's Outline of Advanced Mathematics for
Engineers and Scientists and/or Schaum's Outline of Fourier Analysis with
Applications to Boundary Value Problems (less than $20 each) as a
supplement for extra practice problems and fully worked examples. There will be
supplementary material posted on the class website, http://www4.ncsu.edu/~lubkin/ma501syllabus.html
Grades
final exam 25%, 2 midterms @ 15%, 15% HW and possibly quizzes, 30% team
"projects" (which are like in-depth HW problems).
- The main purpose of HW is give you practice using the
individual methods through solving problems ranging from easy to hard.
Through HW graphical implementation, you will also gain familiarity with
the behavior of solutions of different equations with different IC and BC.
- The main purpose of projects is to give you experience
applying the methods to more complex and/or realistic problems than on the
HW. Your grade on the projects is some indication of your ability to
understand and solve complex problems.
- The main purpose of exams is to determine your fluency with
the essential techniques and underlying concepts. Note that exams measure
different aspects of your learning from HW and projects. You will get
practice tests to try at home the week before an exam.
- I cannot promise that your HW and quizzes will
be graded with great precision, but I can promise that your HW/quiz
grade will be representative of your work.
·
Maple calculations will be required on most of
the assignments. Nobody is expected to purchase Maple;
it is available on campus computers and via VCL
from your own computer. If you have another package that you prefer, you are
free to use it, but I will not teach how to use other packages, nor should you
expect my help with them.
Policies
·
If you have a disability or conflict that I
need to know about, let me know as soon as possible (not the week of the first
exam). Note that I am not sympathetic about vacation plans and cheap airfares.
Your final exam cannot be moved.
·
You are welcome to work on HW with other
students, with some restrictions. Since the
point of HW is learning, you should work with others only to
the extent that it facilitates your learning and your partner's learning.
Giving each other ideas: good. Explaining to each other: good. Finding each
other's errors: good. Copying answers: bad. Letting your partner do the work:
bad.
·
You are welcome to use Maple or any other
computer package to help on the HW. Please say when you are using technological
help. For instance, "Integrating this term by parts (Maple)
yields...."
·
You may not work with others on the exams. Most
quizzes will be a solo effort. Group quizzes will be
specifically identified as such. In accordance with the NCSU policy on
academic integrity, found in the Code of Student Conduct, it is assumed that in
turning in any assignment to the instructor, the student has thereby implicitly
taken the honor pledge: "I have neither given nor received unauthorized
aid on this test or assignment."
Courtesy
- Some of you may need to eat or drink during class. I don't
mind this, but your fellow students might, so please keep noises, crumbs,
and odors under control. Food and drink are generally
not allowed in computer labs.
- What I do mind is the newspaper. Do not attempt to read it in
class.
- If you want to really tick me off and convince me to give an
extra-large assignment, then you should text in class.
- If you are sick, please stay home, rest up, and get the notes
from a classmate.
Homework
aesthetics
- Please staple homeworks. Don't fold in half. Loose sheets get
lost.
- Every graph must be labeled. Always
label all axes. Arrowheads have a very specific meaning indicating the
direction of motion or of a vector or time. Arrows do not belong on axes
or curves unless they are intended to indicate time or
motion or vectors.
- If you are asked to make an argument,
or "show that..." then you need to use enough words to make that
argument. Mathematical symbols without context make no sense. Look at your
textbook: it is mostly words with symbols used within the sentences. That
is how your homework should be written.
- If you do calculations in Maple (for instance) and hand in the
Maple session, the printout should be edited for
clarity and conciseness just as you would edit your handwritten notes
(only giving me your best work). Show me all the necessary lines and don't
show me unnecessary lines. It is easy to make graphs in Maple, but you
should only show those graphs which illustrate
your point. Delete graphs which do not contribute
to your discussion.
- If a solution has both hand-written work and Maple work, the
pages should be next to each other. Do not cluster Maple outputs separate
from handwritten work.
- If you are asked to show an
animation, the ideal way to show it on paper is to use superimposed curves
on the same axes, with some indication of the time sequence. Do not turn
in blank graphs.
Tips
- You are expected
to own the book and read it. You can save money by
getting it used, or getting the international edition (paperback).
However, do not
use the first edition, which is not equivalent to the second edition. Buy
the second
edition.
- Look carefully at your Maple plots and animations. Do they
satisfy the IC and BC? If they look wrong, then your solution is wrong.
- A great amount of learning happens when you correct your own
HW and find your own errors and misconceptions. That is why you will get
solutions. Your engagement with the homework should not stop when you hand
it in.
- Check the website frequently.
- You are expected to check email
daily. I often send reminders or explanations or
assignments by email. You are responsible for making sure that the email
NCSU has for you is the one you check.
- If your Maple outputs are getting too big, print them 2-up, or
resize before printing.
- I tend to respond pretty promptly to
email. I am hard to find by just stopping at my office.
- Did I mention that you should actually read the book?
Links
- Mathworld and Wikipedia are great sites for getting
an overview of an area of math, or finding those obscure formulas that you
vaguely remember (what was a lemniscate, anyway? and that sinh thingy she
was talking about, which I can't even pronounce?) Note: sometimes formulas don't display
correctly in some browsers. The solution is to look at the page in a
different browser.

class (heat, waves, etc.): http://www.falstad.com/mathphysics.html
- Waves: http://www.kettering.edu/~drussell/demos.html
- Handbook
of Mathematical Functions, Milton Abramowitz and Irene Stegun,
courtesy of the US National Bureau of Standards has all the facts you need
on special functions and not-so-special functions. This is what your
grandparents had on their desk if they were engineers or physicists. Now
it's online, and free.
