# Course Descriptions

### MA 004 Review of Math for College (0 credits)

Sets, polynomials, algebra of fractions, linear equations, inequalities of one variable, exponents, radicals, complex numbers, graphing equations, inequalities of two variables, systems of equations, and other selected topics.

Note: No college credit is earned by taking this course.

### MA 106 Topics in Modern Math: Ciphers and Codes

Can you figure out the following message? DOO DUH ZHOFRPH? This message is an example of a cipher. There are a wide variety of different schemes for creating ciphers; in fact, one of the earliest known methods was used by Julius Caesar. The course will focus on those schemes that have a mathematical basis. We will begin with Caesar's method and end with a scheme currently used for security on the Internet. The mathematics used will be elementary and will be developed in the course.

### MA 107 Mathematics, Numbers and the Real World

"This sentence is false." Does this statement make any sense?

Why is 1 not a prime number?

These questions, and even more interesting ones, will be answered as we examine reasoning and logic (inductive and deductive) in a mathematical setting. We will also look at the nature of numbers, including types of numbers and differences among kinds of numbers. We will examine the uses of numbers in real world applications such as interest, installment buying, amortization, etc. We will also look at the fascinating world of probability. For example, how many people have to be in a room so that the chances of two of them having the same birthday not counting the year are 50-50?

The philosopher Proclus described mathematics as "the invisible form of the soul." In this course, you will experience mathematics in ways that you never thought possible. We will discover the power and beauty of mathematics by exploring some very intriguing ideas. Simultaneously, we will learn effective strategies for thinking and making decisions in our everyday lives. Some of the topics we will examine are: the beauty of numbers (What does the number of spirals on a pineapple have to do with rabbits?), infinity (Are some infinities larger than others?), modular arithmetic (On what day of the week will your birthday fall in 2057?), and financial management (How much do you need to save each month if you want to have $5000 saved up when you graduate?).

### MA 421 Analysis I

Calculus is an important tool (perhaps the most important) in applied mathematics and in order to apply Calculus successfully it is important that a thorough understanding of Calculus is achieved. In Analysis I we will explore the definitions and rigorously prove many of the results used in differential and integral Calculus, and thus the course will have a theoretical component. The ideas and methods explored play a fundamental role in many applied mathematical areas such as ordinary differential equations, probability theory (and thus statistics), numerical analysis, and complex analysis.

**Prerequisites:** MA 395

This course is required for the major and is usually taken in the junior year. It is offered only in the Fall Semester.

### MA 422 Analysis II

We will then talk about functions from Rn to Rm and what differentiation and integration means in the context of different combinations of values for n and m. For example, functions from Rn to R were studied in Calculus III, leading to partial derivatives and multiple integrals. Functions from R to R3 describe curves in space. Functions from Rn to Rm where n and m are both greater than 1 are new and will be discussed.

**Prerequisites:** MA351 and MA 421

This course is required for the Pure Mathematics Concentrations; it may be used for the Statistics, Operations Research, Secondary Education and General Program Concentrations. It is offered only in the Spring Semester of even numbered years.

### MA 424 Complex Analysis

The subject of Complex Analysis has both pure and applied components. On one hand, one can think of complex functions as natural extensions of real functions. We will study the topology of the complex plane as we define the concepts of complex functions, the derivative and integral. On the other hand, complex functions are often used to solve problems in a wide variety of applied areas such as electrical engineering (e.g., electric circuits) and physics (e.g., air flow around an airplane wing). While applications will be introduced, our main focus will be on understanding the mathematical concepts.

**Prerequisites:** MA 351

### MA 427 Numerical Analysis

This is an introductory course in numerical analysis, the study of methods for obtaining approximate values of mathematically-defined quantities. Since most uses of mathematics in modern day society involve numerical approximation, this course is essential for any student who wishes to work in an area which involves applied mathematics.

Derivation of the methods and analysis of their errors will be presented. Errors (not to be confused with mistakes) are an inevitable part of using finite algorithms in finite-precision arithmetic, and a numerical method is not usually useful unless the errors can be controlled or at least estimated. For this reason the course has an important theoretical component.

At the same time, one of the goals of the course is to give students experience with the practical performance of the algorithms. To this end the software package MATLAB will be used to implement (and test) the algorithms we will study in class.

Topics include: linear systems, interpolation, quadrature, root-finding. Additional topics may include solutions of differential equations, optimization, and nonlinear systems of equations.

**Prerequisites:** MA 302, and MA351, or written permission of the instructor.

### MA 441 Algebraic Structures I

Groups, rings, and fields form the topics of study. Applications may include symmetries of geometrical objects, arithmetic with large integers, and combinatorial problem solving.

**Prerequisites:** MA 301, MA 395

This course is required for the Pure Mathematics, Computer Science, Secondary Education and General Program Concentrations. It is offered only in the Fall Semester.
