Required Textbook

A First Course in Diﬀerential Equation, by Dennis G. Zill. Brookes-Cole, 11e, ISBN 9781305965720 (2017). Stu-

dents purchasing the text for MATH 2204 should be aware that each instructor may choose to use or not

use the online homework package oﬀered by the publisher as part of their assessment, e.g., counting on-

line homework as part of the student’s grade, however once the seal on the software is broken, the package

cannot be returned for a refund.

All students, regardless of their instructors policies regarding online homework, are encouraged to be-

come familiar with and use online homework as a tool to augment their study of diﬀerential equations.

Course Objectives

The course, MATH 2204, provides a foundation in the theory and solution of ordinary diﬀerential equations

(ODEs). The emphasis is on connecting mathematical concepts with practical modeling applications that can

be applied to solving problems that arise in engineering and the applied sciences. Foundational concepts

in calculus and linear analysis are stressed throughout the course, particularly working with series. These

contribute to a fuller understanding of the analytical approach to solving ODEs.

1. Have an understanding of several elementary and classical methods for solving ODEs;

2. Appreciate the structure of the solution, and its relationship to underlying mathematical ideas; and,

3. Be able to formulate and ﬁnd solutions to mathematical problems in the applied sciences and engineer-

ing involving diﬀerential equations.

The emphasis is on improved critical thinking skills with regard to using extending the methods of calculus

to solving elementary problems involving diﬀerential equations. Theory and analysis is stressed throughout,

however the course also requires that the student develop proﬁciency in working with solution methods for

ODEs that are covered in the text.

Student Learning Outcomes

After successfully completing this course the expectation is that students will be able to:

1. Work with and understand the concept of existence and uniqueness of solutions;

2. Apply principals of linearity to solve a range of problems involving diﬀerential equations;

3. Formulate solutions to problems involving ODEs, using multiple approaches if necessary.

4. Apply solution techniques to solve ﬁrst and second order diﬀerential equation, including homogeneous

and inhomogeneous problems.

5. Apply graphical and numerical methods to solve problems involving ODEs; and,

6. Apply Laplace Transforms to the solution of diﬀerential equations, particularly to constant coeﬃcient,

linear ODEs.

Department, College and University Expectations and Policies

It is important that students familiarize themselves with a range of policies and guidelines that have been es-

tablished by the Department of Mathematics and Physics, the College of Arts and Sciences, and the University

of New Haven. These are an integral part of the syllabus for this course.

Adding/Dropping a Class

The ﬁnal day to drop this course without it appearing on your transcript is discussed on the

Academic Schedules and Registration web page. After the ﬁrst week of class, self-service registration will

not be enabled for students to directly add or drop classes. Students should contact the Registrar’s oﬃce

directly or the Academic Success Center for assistance with adding and dropping courses during this time.

Attendance Regulations

University attendance policy guidelines require that:

Students are expected to attend regularly and promptly all their classes, appointments, and exercises. While the

university recognizes that some absences may occasionally be necessary, these should be held to a minimum.

A maximum of two weeks of absences will be permitted for illness and emergencies. The instructor has the

right to dismiss from class any student who has been absent more than the maximum allowed. A dismissed

student will receive a withdrawal (W) from the course if they are still eligible for a withdrawal per the university

Withdrawal from a Course policy, or a failure (F), if not. A student who is not oﬃcially registered in the course

is not permitted to attend classes or take part in any other course activities. Students absent from any class

meeting are responsible for making up missed assignments and examinations at the discretion of the instructor.

Students are to adhere to the policy attendance policy guidelines outlined in the University Catalog under the

heading, Attendance Regulations, found online in the Undergradaduate Catalog or alternatively found in the

Student Handbook on pp.4849.

Religious Observance Policy for Students

The University of New Haven respects the right of its students to observe religious holidays that may neces-

sitate their absence from class or from other required university-sponsored activities. Students who wish

to observe such holidays should not be penalized for their absence, although in academic courses they are

responsible for making up missed work. The College provides that,

Instructors should try to avoid scheduling exams or quizzes on religious holidays, but where such conﬂicts occur

should provide reasonable accommodations for missed assignment deadlines or exams. If a class, an assign-

ment due date, or exam interferes with the observance of such a religious holiday, it is the student’s responsibil-

ity to notify their instructor, preferably at the beginning of the term, but otherwise at least two weeks before the

holiday.

More information about religious observance policies can be found in the Student Handbook on pp.4849

under the heading, Attendance Policies: Religious Observance Policy for Students.

Withdrawal from a Course

Students wishing to withdraw must submit a request for an oﬃcial course withdrawal in writing using the on-

line Course Withdrawal Form, or alternatively complete and hand in the pdf based Course Withdrawal Form.

The ﬁnal date to request a withdrawal is listed in the Academic Calendar. This request must be submitted to

the Registrar’s Oﬃce and signed by the International Oﬃce if you are an international student. The grade of

W will be recorded, but the course will not aﬀect the GPA.

1

Incomplete Grade Policy

A grade of Incomplete (INC) is given only in special circumstances and indicates that the student has been

given permission by the instructor to complete required course work (with the same instructor) after the end

1

Please note that it is the responsibility of the student to assure that the required paperwork and documentation is completed by the deadline.

Department Syllabus for MATH 2204, Spring 2019 Page 4 of 7 Rev. 1.0, January 28, 2019

of the term. In the absence of the instructor a student should contact the Department Chair. Students need

to examine carefully the changed guidelines pertaining to INC grades, speciﬁcally:

To remove the INC grade, the student must complete all required course work in timely fashion as stipulated by

the instructor but no later than the end of the following term. Fall and intersession course incomplete grades

must be completed no later than the last day of the spring term. Spring and summer course incomplete grades

must be completed no later than the last day of the fall term.

If the course work is not submitted within the allotted time, the INC grade will be changed to an F shortly after

the deadline by the Oﬃce of the University Registrar. Students will be notiﬁed via campus email at least two

weeks prior to the change of grade process.

The University policy on incomplete grades is discussed in the Academic Catalog under the heading, Incom-

plete (INC) Grade Policy.

Academic Integrity Policy and Procedures

The University of New Haven expects its students to maintain the highest standards of academic conduct.

Academic dishonesty is not tolerated at the University. To know what it is expected, students are responsible

for reading and understanding the statement regarding academic honesty in the Student Handbook. Specif-

ically, students are required to adhere to the Academic Integrity Policies speciﬁed in the Student Handbook,

i.e., on pp.6673.

Please ask your instructor about their expectations regarding permissible or encouraged forms of student

collaboration if there is any confusion about this topic. The Department of Mathematics and Physics fully

adheres to the Academic Integrity Policy:

Academic integrity is a core university value that ensures respect for the academic reputation of the University,

its students, faculty and staﬀ, and the degrees it confers. The University expects that students will conduct

themselves in an honest and ethical manner and respect the intellectual work of others. Please be familiar with

the University’s policy on Academic Integrity. Please ask about expectations regarding permissible or encouraged

forms of student collaboration if they are unclear.

Coursework Expectations

This course will require signiﬁcant in-class and out-of-class commitment from each student. The University

estimates that a student should expect to spend two hours outside of class for each hour they are in a

class. For example, a three credit course would average six [6] hours of additional work outside of class.

2

Coursework expectations are detailed in the Academic Catalog under the heading, Course Work Expectations.

Please note, that MATH 2204 is a 3-credit course, and as such requires a total of 9 hours per week invested

in study and homework for the average student.

Commitment to Positive Learning Environment

The University adheres to the philosophy that all community members should enjoy an environment free of

any form of harassment, sexual misconduct, discrimination, or intimate partner violence. If you have been

the victim of sexual misconduct we encourage you to report this. If you report this to a faculty/staﬀ member,

they must notify our college’s Title IX coordinator about the basic facts of the incident (you may choose to

request conﬁdentiality from the University). If you encounter sexual harassment, sexual misconduct, sexual

assault, or discrimination based on race, color, religion, age, national origin, ancestry, sex, sexual orientation,

gender identity, or disability please contact the Title IX Coordinator, Caroline Koziatek at (203)-932-7479 or

CKoziatek@newhaven.edu. Further online information about is available at Title IX.

Reporting Bias Incidents

At the University of New Haven, there is an expectation that all community members are committed to cre-

ating and supporting a climate which promotes civility, mutual respect, and open-mindedness. There also

exists an understanding that with the freedom of expression comes the responsibility to support community

2

Please note that study guidelines are important, i.e., there is substantial evidence that shows that the pass rates for students in math courses decrease

dramatically as the time spent on outside study falls below 2 hours of homework per credit per week.

Department Syllabus for MATH 2204, Spring 2019 Page 5 of 7 Rev. 1.0, January 28, 2019

members’ right to live and work in an environment free from harassment and fear. It is expected that all mem-

bers of the University community will engage in anti-bias behavior and refrain from actions that intimidate,

humiliate, or demean persons or groups or that undermine their security or self-esteem.

If you have witnessed or are the target of a bias-motivated incident, please contact the Oﬃce of the Dean

of Students at 203-932-7432 or Campus Police at 203-932-7014. Further information about this and other

reporting options may be found at Report It.
