Math
3400 (Number Theory)
Spring 2003, UNT
Lecture: GAB 204, MWF 11:00-11:50am
Instructor: Professor
Olav Richter
Course Description: In Math 3400, we will discuss prime numbers and the
Fundamental Theorem of Arithmetic. Congruences play a crucial role in this
course. We will cover several special congruences such as Wilson's Theorem,
Fermat's Little Theorem, and Euler's Theorem. In addition, we will investigate
the Perpetual Calendar and, as a fun application of congruences, we will learn
how to quickly compute the weekday of any given date! We will also cover
various other important topics in Number Theory such as Multiplicative
Functions, Primitive Roots, and Quadratic Residues.
Prerequisites for Math 3400: Math 3510.
Textbook:
Homework: Here is a
complete list of homework problems for this course. Homework will be assigned
at the end of each lecture. Homework will be due on Fridays by 11:50 am and you
can turn it in before or after (but not during) class. Here you can
check to see which sections are due when. Homework will be returned in class. Late homework will NOT be accepted for any reason.
Your lowest two homework scores will be dropped.
Exams & Grading
Policy: Your final grade will be
based on your homework (your lowest two homework scores will be dropped), two
midterms, and a comprehensive final. The midterms will be on February 24 and
April 14. The final exam will be on May 7th. Please make sure that you are
available at those dates, since there will be NO make up exams!
The grade is comprised of
You are encouraged to study
together and help each other throughout the semester. If everyone does well,
everyone will receive a good grade.
Expectations: A fair amount of work is involved in learning Number
Theory. You are expected to come to lecture on time. Plan ahead so you are not
late. You should come to every lecture, and come prepared. If you have to miss
class or if you are late for some unavoidable reason it is your responsibility
to obtain notes from another student if you miss class. You are expected to
read the assigned sections and work on the homework problems immediately after
they are assigned. You should be prepared to ask questions, take notes, and
look alive in class. Please bring your text book to class and leave the cell
phone at home. Repeat: NO CELL PHONES OR PAGERS!!! In addition to attending
lecture, you should spend at least 6 hours per week on my course.
Extra Credit: Do NOT expect to be able to do some extra work to help
your grade either before or after the final exam. There will be NO extra credit
other than perhaps an extra problem on an exam.
Some Advice: Math is not a spectator sport. Work through problems
and examples and text, instead of just reading. Make many notes in the margins
and redo each and every example from the book and from lecture. You will not
learn Number Theory from watching the professor or friends display ideas and
solve problems. You must try problems, finish problems, ask questions, correct
your mistakes, put concepts in your own words, and practice, practice,
practice! The good news: A small increase in effort usually results in a big
increase in success!
Disabilities: It is the responsibility of students with certified
disabilities to provide the instructor with appropriate documentation from the Dean
of Students Office.
Cheating: No cheating will be tolerated. Anyone caught cheating will receive an F
in the course. Furthermore, a letter will be sent to the appropriate dean.
Lecture schedule: In the very unlikely event that you missed a lecture
you can check here to see what material I covered in class. I will update the
Actual Lecture Schedule after every class.
