# Course Description

#### Textbook

Discrete Mathematics and Its Applications, fifth edition, Kenneth H. Rosen, McGraw-Hill, 2003 (ISBN 0-07-242434-6).

#### Prerequisites

The prerequisite for this course is MATH 151 Calculus & Analytic Geometry I or its equivalent. MATH 140 Differential Calculus is an acceptable substitute. There is also a programming corequisite: you should have taken or be currently taking a programming course such as CMSC 201. If you are unsure about the programming corequisite, consult the instructor.

#### Objectives

This course is a prerequisite for several required courses for computer science and computer engineering majors including: CMPE 212, CMSC 313, CMSC 341 and CMSC 441. It is also a highly recommended course for mathematics majors prior to taking MATH 301 Introduction to Mathematical Analysis. As such the main objectives of this course are: 1) to train the students to read and write mathematical proofs; 2) to develop the students' mathematical problem solving skills; and 3) to familiarize the students with standard concepts in discrete mathematics.

Final grades will be based upon homework assignments (26% total), quizzes (48% total) and the final exam (26%). The syllabus lists 13 homework assignments and 6 quizzes. However, if a homework assignment or quiz is canceled and not made up (e.g., because school is closed for snow or some other emergency), the proportion of your grade from homework, quizzes and the final exam will remain the same. That is, homework will still count for 26% of your grade and quizzes 48% of your grade (each homework or quiz will have greater weight).

The final letter grades are based on the standard formula:

0 ≤ F < 60,    60 ≤ D < 70,    70 ≤ C < 80, 80 ≤ B < 90,    90 ≤ A ≤ 100

Depending upon the final distribution of grades in the class, there may be a curve in your favor, but under no circumstances will grades be curved downward.

Grades are given for work done during the semester; incomplete grades will only be given for medical illness or other such dire circumstances.

#### Quizzes

In-class quizzes are scheduled for Thursday 2/23, 3/9, 3/30, 4/13, 4/27 and 5/11. Make every effort to attend --- unexcused absences will result in a grade of zero for that quiz. Each quiz will be held during the last 30 minutes of the class period.

Since quizzes account for 48% of your final grade, it is the main evaluative instrument for this class. You should think of the homework as practice for the quizzes and the final exam as a second chance to show you have learned the material.

At least half of the credit for each quiz will be from a question that requires you to solve a new problem (i.e., not simply a regurgitation of facts). In order to do well in these quizzes, you must be able to do the types of questions assigned for homework on your own. If you do not learn from doing your homework, you will not pass the quizzes.

#### Lecture and Homework Policy

You are expected to attend all lectures. You are responsible for all material covered in the lecture as well as those in the assigned reading. However, this subject cannot be learned simply by listening to the lectures and reading the book. In order to master the material, you need to spend time outside the classroom, to think, to work out the homework and understand the solutions.

Assignments are due at the beginning of lecture. Late homework will not be accepted --- this is to allow for timely grading and discussion of the homework solutions. Reasonable provisions will be made for students who are delayed by traffic, who are on travel, ... Late homework will be rejected from students who have obviously been working on homework instead of attending lecture.

Partial credit will be given for serious attempts on the homework problems. So you should simply turn in whatever you have accomplished by the beginning of class. If you cannot attend lecture when homework is due, for some honorable reason, you must make arrangements to submit your homework directly to the instructor. Do not ask another student to submit your homework for you. This is to reduce the temptation to cheat (see below).
