Course Organisation

 


The learning material for this course consists of nine components. These are:

1.      A Course Profile

2.      A Textbook: Discrete Mathematics with Applications, by Susanna Epp.

3.      A Study Guide (at front of Workbook)

4.      A Workbook

5.      A Reader (at back of Workbook)

6.      Assignment Questions

7.      Practice Midsemester and Practice End of Semester Exams

8.      Solutions to Assignments and Practice Midsemester and End of Semester Exams (available on webpage)

9.      Course Web Page:  http://www.maths.uq.edu.au/~dmd/teaching/MATH1061/MATH1061-5-2004.htm

 

Students purchase the textbook. The Workbook can be purchased (see Course Profile for details) or down-loaded from the Course Web Page.

 

The Course Profile lists all the administrative information relevant to this course, you must read it.

 

The Textbook is the basic resource material on which the course is based. All students require a copy of this book.

 

The Study Guide gives a detailed description of the material to be covered in this course. It is important to read this documents as it tells you what to study and when to study it.

 

The Workbook is for students to record important definitions and theorems. It also provides extra examples which students may work. Note that the numbering of sections in the workbook follows the numbering of the corresponding sections in the textbook, but not in the same order as the textbook. Solutions to all exercises presented in the Workbook are available on the Course Web Page. 

 

The Reader contains extra material not presented in the textbook. The Study Guide directs students to the Reader when necessary

 

Assignments are usually set on a weekly basis, three of these will could towards assessment. For information relating to assessment of assignments refer to the Course Profile.

 

Practice Midsemester and Practice End of Semester Exams are provided as they give an indication of the standards of assessment for this course.

 

Solutions to Assignments and practice exams can be obtained from the web page.

 

The Course Web Page should be checked regularly; all important announcements are posted on this web page. It also contains links to files for the Workbook, Solutions to the Workbook, the Reader and Solutions to Assignments.

STUDY GUIDE

 

Students should use this guide to plan their study. Each section of the Study Guide directs students to:

1.      Read background material (includes detailed information of relevant pages in the textbook or reader).

2.      Write a summary of reading material in the workbook and to work extra examples to reinforce the ideas covered in the reading. 

3.      Work extra problems the check to material has been fully understood. You should make sure you do these problems.

 

The sequencing of material follows the order in which the material will be presented in lectures. The numbering of chapters and sections roughly follows the numbering used in the textbook. For instance we will study Chapter 11, of the textbook, immediately after Chapter 5. We will not study Chapter 9 of the textbook and we include a final chapter on groups and fields which is not covered in the textbook. To try and reduce confusion, the numbering of chapters and sections in the study guide (and the workbook and reader) follows the numbers of the chapters and sections in the textbook. Hence the order we follow is:

 

Chapter 1:            Sections 1.1, 1.2, 1.3 and 1.4

Chapter 2:                  Sections 2.1, 2.2 and 2.3

Chapter 3:                  Sections 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9 and 3.10

Chapter 4:                  Sections 4.1, 4.2, 4.3 and 4.4

Chapter 5:                  Sections 5.1, 5.2 and 5.3

Chapter 11:                Sections 11.1, 11.2, 11.3 and 11.5

Chapter 10:                          Sections 10.1, 10.2, 10.3 and 10.5

Chapter 7:                  Sections 7.1, 12.2, 7.2, 7.3, 7.4 and 7.5

The Last Chapter:     Sections G1, G2 and G3

Chapter 6:                  Sections 6.1, 6.2, 6.3, 6.4, 6.5, 6.6 and 6.7

Chapter 8:                  Sections 8.1, 8.3 and 8.4
