About the Course: This course will provide you with a basic
introduction to the major topics in discrete mathematics, with emphasis on
those topics of relevance to computer science. The emphasis throughout
will be not just on the mathematical facts themselves, but also on the
reasoning that goes into establishing their correctness. In addition to
the basic facts, you will also learn to express mathematical ideas in both
written and verbal form. Clarity of expression is an essential component
of any scientific discipline!
Grading: Your grade will be based on four things (in increasing
order of importance): Homework, Quizzes, the Midterm Exams and the Final.
You will have two midterm exams during the term. They will be in-class
exams. You will have numerous quizzes throughout the term. They will
typically take ten minutes. At the end of the term I will drop your
lowest quiz, and then scale the rest so they count the same as one
midterm. The final will count for one and a half regular exams.
Homework: Homework will be an important part of this class and will
generally be assigned weekly. It will be collected. Unfortunately it is
not practical for me to grade every problem, so I will generally choose
two or three per assignment to grade. The catch is that you won't know
ahead of time which ones I will look at! The neatness and clarity of your
solutions will be factored into your score.
Miscellaneous: Office hours are an integral part of the course. Do not hesitate to come talk to me if you have any concerns at all. If you can not make my office hours,
simply make an appointment with me for some other time. If you have any special needs that I should know about, let me know as soon as possible. Isolated absences do not have to be
explained to me, but if you will miss several classes in a row, please talk to me about it. I can accommodate almost any contingency that comes up (for example, if you have to miss
a test), as long as I know about it ahead of time. The exception is the final exam, which will be on the indicated date and time, barring a truly extraordinary circumstance.
