Topics and goals
Our major goal will be to familiarize ourselves with some of the important tools of discrete mathematics.
- Mathematical language, logic, writing, and proof
- Set theory
- Functions and Relations
- Combinatorics and discrete probability
- Graph theory and trees
Discrete Mathematics: Mathematical Reasoning and Proof with Puzzles, Patterns, and Games, by Douglas E. Ensley and J. Winston Crawley. Wiley, ISBN 0-471-47602-1
The book has a rather helpful companion web site which we will be using on occasion.
Homework : will be assigned weekly (generally assigned and collected on Tuesdays). The homework assigned one Tuesday will include material taught the following Thursday. I'd like to encourage you to read the relevant sections of the book to a) get started on the homework early and b) prepare for the upcoming class. In fairness to the other students in the course, late homework will generally not be accepted. We will, however, drop the lowest homework score in computation of final grades. Please talk to me in cases of emergency.
Quizzes : There will be five quizzes. They are tentatively scheduled as indicated in the syllabus below. Quizzes will start at the beginning of class and run for about 15-20 minutes. We will also drop the lowest quiz.
Midterm : There will one midterm exam. (See calendar below)
Final : The cumulative final examination for this course is scheduled as indicated on the calendar below. I will not be able to accommodate early finals for nonacademic, nonemergency reasons. Please plan your travel schedule accordingly.
Please talk to me ahead of time if you have a scheduling issue with any quiz or exam.
Grades will be computed by a weighted average: [[!table header="no" class="mointable" data=""" Homework | Quizzes | Midterm | Final 10% | 20% | 30% | 40% """]]
Final scores will be converted to letter grades beginning with the following scale:
[[!table header="no" class="mointable" data="""
93 | 90 | 87 | 83 | 80 | 75 | 65 | 50
A | A- | B+ | B | B- | C+ | C | D
As for a curve, these cutoffs might be adjusted, but only in the downward direction (to make letter grades higher).
On the homework, each problem will be worth three points, assigned as follows: [[!table header="no" class="mointable" data=""" Points | Description of Work 3 | Work is completely accurate and essentially perfect. Work is thoroughly developed, neat, and easy to read. Complete sentences are used. 2 | Work is good, but incompletely developed, hard to read, unexplained, or jumbled. Answers which are not explained, even if correct, will generally receive 2 points. Work contains the 'right idea' but is flawed. 1 | Work is sketchy. There is some correct work, but most of the work is incorrect. 0 | Work minimal or non-existent. Solution is completely incorrect. """]]
For the purposes of assembling the final grade, the grade on each homework set is converted to a percentage of all achievable points, on a scale from 0 to 100.
