Prerequisite: “Completion of 6 hours of undergraduate mathematics.”
As a practical matter, you must have a working knowledge of algebra. Several free tutorials may be found on the Internet.
Topics: Course Catalog: “Study of discrete and logical structures for information systems analysis and design including basic set theory and proof techniques, propositional and predicate logic, trees and graphs, finite state machines, formal languages and their relation to automata, computability and computational complexity, formal semanticsoperational, axiomatic and denotational approaches.” We will focus on problem solving.
Textbook: Discrete Mathematics with Applications, 3 edition (December 22, 2003) By Susanna S. Epp, Publ: Brooks Cole; ISBN10: 0534359450; ISBN13: 9780534359454. We will start with mathematical induction, a method of proof with maybe the least conceptual and notational overhead. With that apology, we’ll follow the textbook in this order: Chapters 4, 3, 5, 7, 10, 11, 1, and 12. Note the glossary of symbols inside the front and back covers.
Calculator: You will need a calculator capable of raising numbers to powers. Really!
Exams: We will have: (i) 4 Quizzes, (ii) 2 Hour Exams, and (iii) a comprehensive Final Exam on December 10, 2008. Quizzes will be “closed book,” Exams will be “open book & notes.”
Grades: 1 Final Exam: 40% of final grade.
2 Hour Exams: 20% of final grade each, 40% total.
Homework and quizzes together: remaining 20% of final grade.
Help: Questions? Send me an email! You may also make an appointment with our TA. If you email anything more than simple text, please send a .pdf. (OpenOffice software {free} will allow editing and converting MS Word and Excel documents to a .pdf file. WordPerfect also permits publishing directly to .pdf.)
Homework: Normally, homework will not be accepted late. Exams and Quizzes will never be given late. Always check courses.gmu.edu after class for an updated syllabus with the next week’s homework assignment.
Honor Code: The Honor Code must be followed. Any violations will be reported to the Honor Committee.
