Text:
Discrete Mathematics with Applications, 3rd ed.(or 4th if you already bought it), Susanna S. Epp.

Prerequisites:
MATH 1113.

Technology:
You may want a calculator for large data set arithmetic. The TI-83/84 or TI-89 is acceptable, as are many other calculators. You may NOT share calculators during quizzes or exams. The use of cell phones, pagers, text or other messaging devices is not allowed during class.

Course objectives:
An introduction to the fundamentals of discrete mathematics. Topics include sets, formal logic, methods of proof, counting, relations, functions, and graphs & trees.
Upon completing this course students should be able to:
1. Write a correct formal proof.
2. Write the converse, contrapositive, and negation of a statement.
3. Determine whether a relation is reflexive, symmetric, or transitive.
4. Identify isomorphism invariants of graphs.
5. Construct minimal spanning trees for weighted graphs using Kruskal's and Prim's algorithms.

Homework, Quizzes and Examinations:
Homework will be assigned daily, but will not be collected without advance warning. Questions on homework problems can be answered in Office Hours and/or in class. Quizzes will occur frequently, and occasionally without warning. Quiz questions will typically come from homework problems. There will be four in-class tests, and a final

Tests will be valued at 15% each, quizzes/homework will total to 20%, and the final will be valued at 20%.
A 90% or greater average will be awarded A
An 80% or greater average will be awarded B
A 70% or greater average will be awarded C
A 60% or greater average will be awarded D

Dates:
First day of classes Wednesday June 2
Drop add ends Tuesday June 8
First Test Monday June 14
Second Test Wednesday June 23
Last day to withdraw Thursday June 24
Holiday Monday July 5
Third Test Wednesday July 7
Fourth Test Wednesday July 21
Last day of classes Tuesday July 27
Exams July 28-30

Delivery

This is a Flipped course where all required course lectures and learning activities will take place using asynchronous online course content; however, in-class events (Q&A, Kahoot, homework review, etc) will be offered online during the scheduled times.  You are expected to be prepared for online delivery including arranging access to stable internet capable of handling streaming video demands and a computer with (internal or external) functioning webcam with microphone. Assessments will be in D2L using Respondus Lockdown Browser.

Absence:
If I am contacted with an acceptable excuse before the date of the quiz or exam, then a makeup can be arranged. An acceptable excuse is in writing, contains the student's name, the date of the absence, a signature from a faculty member sponsoring the trip, contact information for the faculty member, and a brief mention of the nature of the trip.

"Important notice: Any student who, because of a disabling condition, may require some special arrangements in order to meet the course requirements should contact the instructor as soon as possible to arrange the necessary accommodations. Students should present appropriate verification from KSU Student Disability Services. No requirements exists that accommodations be made prior to completion of this approved University process."

Withdrawal

Students who find that they cannot continue in college for the entire semester after being enrolled, because of illness or any other reason, need to complete an online form. To completely or partially withdraw from classes at KSU, a student must withdraw online at www.kennesaw.edu, under Owl Express, Student Services.

The date the withdrawal is submitted online will be considered the official KSU withdrawal date which will be used in the calculation of any tuition refund or refund to Federal student aid and/or HOPE scholarship programs. It is advisable to print the final page of the withdrawal for your records. Withdrawals submitted online prior to midnight on the last day to withdraw without academic penalty will receive a “W” grade. Withdrawals after midnight will receive a “WF”. Failure to complete the online withdrawal process will produce no withdrawal from classes. Call the Registrar’s Office at 770-423-6200 during business hours if assistance is needed.

Students may, by means of the same online withdrawal and with the approval of the university Dean, withdraw from individual courses while retaining other courses on their schedules. This option may be exercised up until June 24, 2021.

This is the date to withdraw without academic penalty for Summer Term, 2021 classes. Failure to withdraw by the date above will mean that the student has elected to receive the final grade(s) earned in the course(s). The only exception to those withdrawal regulations will be for those instances that involve unusual and fully documented circumstances.

Assistance:
For help with your homework, or questions about the lectures, you have a lot of options. I will take a limited number of questions during class, as time permits. I am available in my office for help during my posted office hours, and any unscheduled time my door is open. For additional help, there are campus-wide resources I will announce as soon as I have the details.
