Book: John P. D'Angelo and Douglas West: Mathematical Thinking: Problem-Solving and Proofs, 2nd Edition

Course description :   We will essentially  cover chapter 1 to 8 and 13 to 15 (optimistic). Some details:

Plan:
   Introduction of the real numbers
    - motivation
    - axioms of the real numbers
    - some introduction to logic: functions and quantifiers
    - elementary inequalities
   The natural number and the induction principle
   Divisibility and modular arithmetic combined with some reasoning on cardinality
    -Prime number factorization theorem
    -q-nary expansion
    -Existence of  multiplicative inverses
    -Cardinality for finite sets
    -Binomial coefficients and some combinatorics
    -Fermat's little Theorem
   The rational numbers
    - countable and uncountable sets
   Seqeunces and series
   The real numbers system
   Continuous functions
 

Comments: Math 347 is by no means an ordinary course!  Here you may learn what mathematics is all about. You may decide to hate or love it: I hope you will love it. This is the first course where you can learn what mathematics is really about: proofs.  Proofs are not a burden  invented for  students. Proofs create a connection between different objects in mathematics. Proofs are like the oil  in the machine which make it  work.  Thus be prepared for an intense learning exercise. Every mathematician had to start some day learning what you will learn: the basic rules in mathematics. Ask questions!  Don't think everybody knows better than you do-this feeling is common and commonly  wrong.  I strongly recommend study groups, in particular for your homework. Sharing your first experience in understanding proofs is really fun. Moreover, it is through explaning mathematics to to others that we really understand the stuff.

Grading:

Homework: I will grade one problem out of four problems every week (Friday-Friday):  10pt/week, total  130 pts
Midterms: Wednesday, March 1 (100 pts) ,  Friday, April  14 (100 pts), two quizes, tba,   (50 pts)
Final exam:  8:00-11:00 AM, Friday, May 5, (200pts)
Total: 630 pts
After every event quiz, midterm (not homework) you will obtain an update on your performance so far. I expect to give an A for more than 550 points.
