Texts :  How To Prove It: A Structured Approach, 2nd Edition, by Daniel Velleman.

            A First Course in Discrete Mathematics, by Ian Anderson.

Course Meetings:  The course lectures will be held in SMLC 356 on Tuesday s and Thursdays at 8-9:15 am. 

Topics:  Fundamentals of mathematical proof in the context of discrete structures, logic, sets and relations, functions, integers, induction and recursion, counting, permutations and combinations and algorithms.

Homework (200 points):  Homework will be assigned weekly on Thursdays and will be collected the following Thursday at the beginning of class.  Homework will not be graded unless it is written in order and labeled appropriately.   The definitions and theorems in the text and given in class are your tools for the homework proofs. If the theorem has a name, use it. Otherwise, I would prefer that you fully describe the theorem in words that you plan to use, than state by Theorem 3.  Each week around 4 of the assigned problems will be graded. The weekly assignments will each be worth 20 points. I will drop your lowest two homework scores and the remaining homework will be averaged to get a score out of 200. 

Exams (400 points):  I will give two midterms (100 points) and a final (200 points). There are no make up exams. If a test is missed, notify me as soon as possible on the day of the exam. For the midterms only, if you have a legitimate and documented excuse, your grade will be recalculated without that test.  The midterms are tentatively scheduled for Thursday, October 6 and Thursday, November 17.  The Final is on Thursday, December 15, from 7:30 -9:30 am. 

Grades:  General guidelines for letter grades (subject to change; but they won't get any more strict): 90-100% - A; 80-89% - B; 70-79% - C; 60-69% - D; below 60% - F.  In assigning Final Grades for the course, I will compare your grade on all course work (including the Final) and your grade on the Final Exam.  You will receive the better of the two grades.
