**Prerequisite:** MATH 2350 and MATH 2360.

**Text:** *Differential Equations with Boundary-Value Problems,* 7th edition, by
D.G. Zill and M.R. Cullen, published by Cengage.

**Course Description:** This course covers topics in ordinary differential equations: 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 – (1.1, 1.2) Introduction

Chapter 2 – (2.1-2.6) First-Order Differential Equations

Chapter 3 – (3.1-3.2) Modeling with First-Order Differential Equations

Chapter 4 – (4.1-4.4, 4.6, 4.7) Higher-Order Differential Equations

Chapter 5 – (5.1) Modeling with Higher-Order Differential Equations

Chapter 6 – (6.1, 6.3) Series Solutions of Linear Equations

Chapter 7 – (7.1-7.5) Laplace Transforms

**Expected Learning Outcomes:** Students will obtain a thorough knowledge of solution techniques for first-order and for second- and higher-order constant coefficient linear homogenous and nonhomogeneous initial value problems using standard methods of undetermined coefficients and variation of parameters. In addition, the students will acquire a general understanding of how to apply the Laplace transform in solving initial value problems and convolution integral equations. Students will gain an appreciation for some of the applications of ordinary differential equations in biology and engineering.

**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.

**Examination Schedule:**

Midterm 1: Tuesday, September 22.

Midterm 2: Thursday, October 22.

Midterm 3: Thursday, November 19.

FINAL EXAM: Saturday, December 12, 1:30 p.m. – 4:00 p.m. Room MA 010.

**Critical Dates:**

Aug. 27: Classes begin.

Sep. 7: Labor Day. Holiday.

Oct. 12-13: Student Holiday; does not apply to School of Law.

Nov. 2: Last day to drop a course.

Nov. 25-29: Thanksgiving Holiday.

Dec. 9: 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.

**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 using the form
posted online.

*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 a message to confirm the students' email addresses and to inform
about Webwork. If a student does not receive any messages by the
time of the second class (Tuesday, Sep. 1), he/she must contact the
instructor immediately.
