Course Content

Mathematical modeling refers to the process of applying mathematical tools and reasoning to understand the world around us. In this course we will get a glimpse of such process in the context of quite a few case studies from Barnes and Fulford's book. Here is a small sampling of cases. We will analyze some (but probably not all) of these in detail.

All case studies lead to models involving differential equations. Each case study begins with a free-form description of an issue and a simple mathematical model. In most cases, further analysis leads to more accurate but more complicated models. The models are explored using analytical, computational and graphical tools, as appropriate.

Textbook

Mathematical Modeling with Case Studies by Belinda Barnes and Glenn Fulford. You may find 1st edition (2002) “with Maple”, 2nd edition (2008) “with Maple and Matlab”, both in hard and soft cover. Any version will do. We will cover a wide selection of topics from this book, as time permits.

Prerequisites

Math 221 (linear algebra), Math 225 (differential equations), Math 251 (multivariable calculus).

Writing Intensive designation

In Fall 2009 this course received a Writing Intensive (WI) designation. As such, it meets UMBC's General Education Program (GEP) requirements.

Course Objectives

The Writing Component

This course differs from most mathematics courses in that writing is an essential part of the course. The “deliverable” for each homework assignment is a complete and self-contained report that describes the problem, the analysis, calculations, conclusions and citations, written in the style of a technical journal article. There will be around 8 such assignments in the semester. The problems will vary in complexity but a typical report will be around 5 printed pages.

Writing Advice: No Needless Words

Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell.

About LaTeX

Technical writing is easy with the right tool. LaTeX is the computer software of choice for technical writing, especially for articles that contain a lot of mathematics.

LaTeX is closer to being a programming language than a word processor. I will devote some class time to LaTeX tutorials and expect that you will write your assignments using LaTeX.

Once you convince yourself that LaTeX is for you, you should consider buying its manual and keeping it within an arm's reach at all times. The manual, written by the creator of LaTeX, is:

LaTeX: A Document Preparation System by Leslie Lamport.

After you have thoroughly mastered that manual, you may expand your knowledge by reading:

The LaTeX Companion (2nd Edition) by Mittelbach, Goossens, Braams, Carlisle and Rowley.

How to get LaTeX

LaTeX is an open source software. It may be obtained freely and installed on any computer platform.

UMBC's machines
LaTeX is already installed on UMBC's Linux machines in the GL labs and the library. You don't need to do anything special to use it.
Your own Linux machine
All Linux distributions come with LaTeX. If you have your own Linux machine, then you may install LaTeX with a few mouse clicks. Ask me if you don't know how.
On Windows or Mac
Several LaTeX distributions are available for free download. They all share a common core—the differences are in the packaging— so any one of them will do. I recommend TeX Live. You need a certain amount of computer know-how to install it.

About Maple

Maple™ is a computer software for symbolic computations. For example, Maple can factorize the polynomial   2x3 – 9x2 + x + 12   into   (2x – 3) (x – 4) (x+1)   and it can figure out that the general solution of the differential equation   y'' + y = tan x   is   y(x) = c1 cos x + c2 sin x – cos x ln(sec x + tan x).   (Can you?)   In fact, Maple knows just about all the undergraduate and some of the graduate subjects of the standard mathematics curriculum.

As the textbook's subtitle indicates, Maple is used as an analysis aid in the case studies. I will devote some class time to Maple tutorials. Probably you will need to use Maple or something equivalent for most of the homework assignments.

UMBC has a campus site license for Maple therefore Maple is available on all university machines.

Exams and grading

There are are no exams in this course. Your work will be evaluated solely based on the quality of your case study reports.

Homework assignments

I will put homework assignments on this web page as we go along. You may study with others, however I expect that you will write the reports on your own; I don't want to see multiple reports that are minor variations of each other. See The Official UMBC Honors Code at the bottom of this page.

I won't take late reports; please don't ask for exceptions. However one lowest homework grade will be dropped to accommodate unanticipated events.

The Official UMBC Honors Code

By enrolling in this course, each student assumes the responsibilities of an active participant in UMBC's scholarly community in which everyone's academic work and behavior are held to the highest standards of honesty. Cheating, fabrication, plagiarism, and helping others to commit these acts are all forms of academic dishonesty, and they are wrong. Academic misconduct could result in disciplinary action that may include, but is not limited to, suspension or dismissal.
