COURSE DESCRIPTION

The Ideas of Discrete Mathematics are the fundamental to the science and technology specific to the computer age. This subject provides an introduction to some fundamental concepts in Discrete Mathematics for the students. The topics covered include: mathematical logic, proof techniques, especially mathematical induction, set theory, functions, and relations, procedures, recursion, and operation counts, recurrence relations, analysis of algorithms, counting methods, permutations and combinations, graphs and trees.

COURSE OBJECTIVES

The objective of this course is to:

1. develop a foundation of set theory concepts and notation
2. explore a variety of various mathematical structures by focusing on mathematical objects, operations, and resulting properties
3. develop formal logical reasoning techniques and notation
4. demonstrate the application of logic to analyzing and writing proofs
5. develop techniques for counting, permutations and combinations
6. develop the concept of relation through various representations (digraphs, matrices, lists).

COURSE OUTCOMES

At the end of the course student will be able to:

1. Construct proofs using direct proof, proof by contraposition, proof by contradiction, proof by cases
2. Construct mathematical arguments using logical connectives and quantifiers and verify the correctness of an argument using propositional and predicate logic and truth tables.
3. Demonstrate the ability to solve problems using counting techniques and combinatory in the context of discrete probability.
4. Solve problems involving recurrence relations and generating functions.
5. Perform operations on discrete structures such as sets, functions, relations and sequence
