Elementary Differential Equations
MATH 2065, Section 01 - Fall 2017

Last updated: September 18, 2017

Required supplies: You must purchase 5 examination blue books of the type that are normally sold at LSU bookstore to write your exam solutions in. Here 5 is an estimated number.

TA's information : Keng Ooi. Office hours: Thursdays 2-5pm at 109 Lockett Hall. Email: kooi1@lsu.edu

Course webpage : www.math.lsu.edu/~pcnguyen. Please check the course webpage regularly for updated information.

Textbook: Ordinary Differential Equations by W.A. Adkins and M. G. Davidson published by Springer in 2012. A free electronic version of the text  which is linked from LSU library can be found at:
http://link.springer.com.libezp.lib.lsu.edu/book/10.1007%2F978-1-4614-3618-8

Supplemental Materials: 1. Function Properties 2. Table of Integrals. A student solution manual is also available online at Student Solution Manual (on left side of the page, below the ADDITIONAL INFORMATION).

Course Description: This is an introductory course in ordinary differential equations with a particular emphasis on solving linear differential equations. We will cover most (but not all) sections of the text. A list of topics to be covered can be found at List of Topics.

Prerequisite : MATH 1552.

Lectures: Time: MWF 10:30-11:20am. Place: 0211 Tureaud Hall.

Office Hours: MWF 12:30-01:30pm. Location: 204 Lockett Hall.

Exams: There will be three 50-minute in-class exams and one 2-hour comprehensive final exam. No make-up exams will be given, except in extreme cases. If you must miss an exam, you should notify the course instructor well prior to the exam, and the excuse must be a valid, fully documented one and one which is officially approved. The tentative exam dates are as follows:

Exam I: Wed, Sep. 20.
Exam II: Mon, Oct. 16.
Exam III: Fri, Nov. 10.
Final Exam: Fri., Dec. 08, from 10:00-12:00.

Some old exams: The old exams are for the purpose of practicing only. They do not necessarily cover all of the possible questions of the actual exams.

Exam 1 Fall 2015  Fall 2016
Exam 2 Fall 2015  Fall 2016
Exam 3 Fall 2015  Fall 2016

Homework and Quizzes: Homework is assigned daily as shown below but will not be graded. This course is cumulative, so it is of the utmost importance to complete homework daily in order not to fall behind. Doing the homework exercises as they are assigned, and seeking help for those that give you difficulty, are the best strategy for a successful completion of the course. Of course, class attendance is very essential. Note that pop-up quizzes may also be given in class, whereas no make-up will be given for the quizzes.

Grades:
Each in-class exam is worth 100 points and the final exam is worth 150 points. Your quiz grades will also be added (usually 50 points). Thus the total is about 500 points. Grades will be assigned on a cumulative semester basis as follows: 90-93.9% =A-, 94-97.9% =A, 98-100% =A+, 80-82.9% =B-, 83-86.9% =B, 87-89.9% =B+, 70-72.9%=C-, 73-76.9%=C, 77-79.9%=C+, 60-62.9%=D-, 63-66.9%=D, 67-69.9%=D+, and 59.9% or less=F.

Important Dates:
Final date for dropping courses without receiving a grade of "W": Tuesday, Aug. 29, 2017.   
Final date for adding courses for credit and making section changes: Wednesday, Aug. 30, 2017
Final date for resigning from the University and/or dropping courses: Friday, Nov. 3, 2017.
Labor Day holiday: Sep. 04; Fall holidays: Oct. 19-Oct. 22; Thanksgiving holiday: Nov. 22 (noon)-Nov. 26.
Final examinations: Dec. 04-09, and final grades (degree candidate) due: Dec. 12, 9:00am.

Students with Disabilities: If you have a disability that may have some impact on your work in this class and for which you may require accommodations, please see a staff member in the Office of Disability Services (112 Johnston Hall) so that such accommodations can be considered. Students that receive accommodation letters, please meet with me to discuss the provisions of those accommodations as soon as possible.


Syllabus and Homework Problems

A brief summary of matrix algebra can be downloaded at: Matrix Primer. This, together with a knowledge of how to compute determinants for 2x2 and 3x3 matrices, will be all that is needed for the applications to systems that we will be discussing. The material is covered more completely in Chapter 7 of the text. Some exercises on these topics are found in the following sections of Chapter 7 of the text.
