Term:Spring Semester
Course:Math 3050
Title:Discrete Mathematics
Section:101 (Class Number 3763)
Instructor:Mark Barsamian
Contact Information:My contact information is posted on my web page.
Office Hours:My office hours are posted on my web page.

Course Description: Course in discrete mathematical structures and their applications with an introduction to methods of proofs. The main topics are introductions to logic and elementary set theory, basic number theory, induction and recursion, counting techniques, graph theory and algorithms. Applications may include discrete and network optimization, discrete probability and algorithmic efficiency.

Prerequisites: MATH 113 or MATH 1200 or Placement level 2 or higher.

Note: Students cannot earn credit for both MATH 3050 and either of CS 3000. (If a student takes both courses, the first course taken is deducted.)

Class meetings: Section 101 (Class Number 3763) Meets Mon, Wed, Fri 12:55pm - 1:50m in Morton Hall Room 218.

Final Exam Date and Time: Section 101 (Class Number 3763) will have its final exam in the late afternoon on the last day of finals: from 3:10pm to 5:10 pm on Friday, April 28. If this exam date and time is not good for you, then don't register for this course. I will not give you an earlier final exam to accommodate your personal travel plans.

Syllabus: For Section 101 (Class Number 3763), this web page replaces the usual paper syllabus. If you need a paper syllabus (now or in the future), print this web page.

Calculators will not be allowed on exams.

Websites with Useful Math Software: In lectures, I often use a computer for calculating. The software that I use is free and is easily accessible at the following list of links. I use the same software in my office, instead of a calculator. You are encouraged to use this same free software instead of a calculator. (Link)

Special Needs: If you have physical, psychiatric, or learning disabilities that require accommodations, please let me know as soon as possible so that your needs may be appropriately met.

Attendance Policy: Attendance is required for all lectures and exams, and will be recorded.

Missing Class: If you miss a class for any reason, it is your responsibility to copy someone’s notes or download my notes from the course web page, and study them. I will not use office hours to teach topics discussed in class to students who were absent.

Missing an Exam Because of Illness: If you are too sick to take an exam, then you must

  1. send me an e-mail before the exam, telling me that you are going to miss it because of illness, then
  2. then go to the Hudson Student Health Center.
  3. Later, you will need to bring me documentation from Hudson showing that you were treated there.
Without those three things, you will not be given a make-up.

Missing Exams Because of University Activity: If you have a University Activity that conflicts with one of our exams, you must contact me before the exam to discuss arrangements for a make-up. I will need to see documentation of your activity. If you miss an exam because of a University Activity without notifying me in advance, you will not be given a make-up.

Missing Exams Because of Personal Travel Plans: All of our In-Class Exams are on Fridays, and our Final Exam is in the late afternoon on the last day of finals (3:10pm - 5:10pm on Friday, April 28, 2016). Please don't bother asking me if you can make up an exam, or take it early, because your ride home is leaving earlier in the day, or because you already bought a plane ticket with an early departure time. The answer is, No you may not have a make-up exam, or take the exam early. You will just have to change your travel plans or forfeit that exam.

Cheating on Quizzes or Exams: If cheat on a quiz or exam, you will receive a zero on that quiz or exam and I will submit a report to the Office of Community Standards and Student Responsibility (OCSSR). If you cheat on another quiz or exam, you will receive a grade of F in the course and I will again submit a report to the OCSSR.

Grading for Section 101: During the semester, you will accumulate points as described in the table below. (Note that no scores are dropped.)

Class Participation (36 class meetings, 3 points each *)100 points possible
Homework (10 assignments, 20 points each):200 points possible
In-Class Exams (best 3 of 4 exams, 150 points each):450 points possible
Cumulative Final Exam:250 points possible
Total:1000 points possible

(* Notice that it is actually possible to score 108 points through Class Participation. Any points scored over 100 will be considered as extra credit points.)

At the end of the semester, your Total will be converted to your Course Grade as described in the table below. (Note that there is no curve.)

Total ScorePercentageGradeInterpretation

600 - 69960% - 69.9%D-, D, D+You mastered some essential concepts.

Blackboard Gradebook: Throughout the semester, your current scores and current course grade will be available in an online gradebook on the Blackboard system.

Class Participation: In MATH 3050 Section 101, the class meetings will be run as seminars, not lectures, so your participation is essential. I will give each of you a small assignment to prepare for discussion in each class meeting. Starting with Day 2 (Wednesday, January 11), you will have a class participation score for each class meeting, a score that indicates your contribution to the classroom discussion. The class participation score for each class meeting will be either 0, 1, 2, or 3, computed as follows:

The daily assignments are found at links in the calendar at the bottom of this web page. The complete list of topics can also be found at this link: (Topic Assignments)

Please note that the Class Participation assignments cannot be made-up in the case of absence, even excused absence, because they involve participation in a class discussion.

Homework: One learns math primarily by trying to solve problems. For that reason, homework plays a central role in Math 3050 Section 101. There are two kinds of homework: suggested homework problems and assigned homework sets.

The suggested homework problems, shown in the table below, are selected from the textbook. These problems are not to be turned in and are not part of your grade. But in order to learn the material covered in the course, you should do as many of the suggested problems as possible and keep your solutions in a notebook for study.

The ten assigned homework sets are to be turned in and will be graded. The problems for each homework set are provided on the cover sheet found at the link provided in the list below. For each of the assigned homework sets, you should do the following:
