Math 03.160 Discrete Structures

Math 03.160 Discrete Structures                                                                                     3s.h.

(Prerequisites: Math-01.122 Precalculus or Math-01.130 Calculus I or permission of the department of mathematics or permission of the department of computer science)

This course covers mathematical topics essential for work in computer science. This material includes number bases, mathematical induction, sets, relations, functions, congruence, recursion, combinatorics, graphs, trees, logic, Boolean algebras, and proof techniques. While this is a course in mathematics, many of the examples and applications will be taken from computer science. The instructor may require use of a graphing calculator and / or computer. This course covers much of the same material as Discrete Mathematics (1703.150), but with a computer science focus. In no case

will a student be allowed to receive credit for both courses. Both courses will be treated as equivalent for the purposes

of satisfying prerequisites and course requirements.

a)      Objectives in Relation to Student Outcomes

Upon completion of this course, students should be able to:

1.         Calculate using binary and hexadecimal arithmetic

2.         Understand and use mathematical induction and other techniques to prove mathematical results.

3.         Understand and work with sets, relations, functions, and congruences.

4.         Perform computations using recursively defined functions and structures.

5.         Use methods of combinatorics to solve counting problems.

6.         Illustrate the basic terminology and properties of graphs and trees, as well as relate graphs andtrees to algorithms and counting.

7.

Demonstrate knowledge of logical reasoning, manipulate formal

prepositional logic, and evaluate Boolean expressions.
