Prerequisite: MATH 2350.

Text: Advanced Engineering Mathematics, by Dennis G. Zill and Michael R. Cullen, 4th Revised Edition, published by Jones & Bartlett (2011)

Course Description: This course covers topics in ordinary differential equations. Topics to be covered include: First-order differential equations; Modeling with first-order differential equations; Higher-order differential equations; Modeling with higher-order differential equations; Laplace transform; Series Solutions of Linear Equations.

Course Outline:

• Chapter 1 - Introduction: Sections 1.1, 1.2

• Chapter 2 - First-Order Differential Equations: Sections 2.1-2.8

• Chapter 3 - Higher-Order Differential Equations: Sections 3.1-3.6 and 3.8

• Chapter 4 - Laplace Transforms: Sections 4.1-4.5

• Chapter 5 - Series Solutions of Linear Equations: Sections 5.1, 5.3

• Chapter 6 (Selected Topics) - Numerical Solutions of Ordinary Differential Equations: Sections 6.1-6.4

Expected Learning Outcomes: The students will study topics of differential equations, their solutions, and applications to physical sciences and engineering. In particular the students will learn to

1. recognize a differential equation and its solution,

2. compute solutions of first order differential equations,

3. compute solutions of higher order differential equations,

4. use Laplace transforms,

5. understand the fundamental properties of power series, and how to use them to solve linear differential equations.

Methods of Assessment of Learning Outcomes: Assessment of the learning outcomes will be achieved through homework assignments, three midterm exams, and a final exam.

Grading policy: Homework will be assigned weekly and will count for 25% of the grade. The lowest homework score will be dropped. There will be three midterm exams in class, each will count for 15% of the grade. The final exam will count for 30% of the grade. All in-class exams are closed-book. No make-up exams are given unless legitimate documents for excuses are presented to the instructor at least a week in advance.
Grading Scale: A: 90%-100%, B: 80%-89%, C: 70%-79%, D: 60%-69%, F: below 60%

Homework assignments: Online homework will be assigned though Webwork. Students will receive the instructor's message for login information. Due dates are indicated on each assignment. Students should spend very first week to get familiar with the system.

Calculators: Only scientific calculators are allowed in exams. These calculators can calculate the values of the standard algebraic, trigonometric, exponential and logarithmic functions. Graphing calculators and calculators that can do symbolic manipulations are not allowed.

Attendance Policy: Students must go to lectures and attendance will be taken. If you miss no more than four lectures, a bonus of three points will be added to your final grade.

Examination Schedule:

• Midterm 1: Thursday, September 22

• Midterm 2: Thursday, October 20

• Midterm 3: Thursday, November 17

• FINAL EXAM: 7:30 a.m. – 10:00 a.m, Monday, December 12, 2011. Room MA 112.

Critical Dates:

• August 25, Thursday: Classes begin.
• September 5, Monday: Labor Day. University holiday.
• September 12, Monday: Last day to drop a course and receive a refund.
• October 10 – 11, Monday – Tuesday: Student holiday.
• October 31, Monday: Last day for student-initiated drop on MyTech with penalty
• November 23 – 27, Wednesday – Sunday: Thanksgiving holiday.
• December 1 – 7, Thursday – Wednesday: No examinations.
• December 7, Wednesday: Last day of classes.

Academic Misconduct: Academic dishonesty is intolerable and will be punished to the full extent allowed by the University policy.

Civility in the Classroom: Students are expected to assist in maintaining a classroom environment that is conducive to learning. In order to assure that all students have the opportunity to gain from time spent in class, unless otherwise approved by the instructor, students are prohibited from engaging in any other form of distraction. Inappropriate behavior in the classroom shall result, minimally, in a request to leave class.

Students with Disabilities: Any student who because of a disability may require special arrangements in order to meet course requirements should contact the instructor as soon as possible. "I would appreciate hearing from anyone who has a disability that may require special accommodations. I am sure we can work out whatever arrangements are necessary. Please see me during my office hours."

Advice: Come to class regularly, work on homework problems. Ask questions in class and get help from the instructor during the office hours. Master the material quickly and do not wait too late until the midterms or the final exam. Students are encouraged to give feedbacks to the instructor during the semester.

NOTE: When needed, the instructor will communicate with the students using their TTU email addresses. At the beginning of the semester, the instructor will send out two special email messages. One is to confirm the students' email addresses, the other one is about Webwork. If a student does not receive those messages by the time of the second class (Tuesday, Aug. 30), he/she must contact the instructor immediately.
