MathematicsOffered by the Mathematics department.
Understand the central role of mathematics in the modern world.
We have a very friendly, supportive community of students and faculty who believe that mathematics is both beautiful and applicable and is one of pillars that supports Wheaton’s mission as a liberal arts college. You will learn to think like a mathematician at Wheaton, and this will serve you well no matter where your future takes you.
In addition to the traditional courses in pure mathematics, such as Calculus, Linear Algebra, and Real Analysis, we also offer a set of courses that highlight recent developments in mathematics, including sophomorelevel courses in Data Analysis, Voting Theory, and Cryptography.
We know that our students have a wide range of interests, so we have intentionally structured our program with enough flexibility that you can easily study abroad and have the space to explore other academic pursuits as well. Our recent Math majors have taken full advantage of these opportunities. Some completed a second major in a discipline you may expect, such as Physics, Economics, Secondary Education, and Computer Science, but others have a second major in an area you may find surprising, such as Psychology, Philosophy, Hispanic Studies, English and French Studies.
We pride ourselves on working closely with our students to help each one find the path that is the best fit for them. This is reflected in the many different directions our majors have taken after graduation. Some have pursued graduate school in pure mathematics, applied mathematics, or statistics, and others have chosen careers in business, finance, high school teaching, epidemiology, medicine, law, or technology fields, to name just a few.
We have beauiful spaces for our students and faculty to collaborate that are filled with chalkboards and whiteboards, including an outdoor classroom. Please stop by to visit us on the first floor of the Science Center!

Mathematics
MATH 099 – Independent Study
An opportunity to do independent work in a particular area not included in the regular courses.

Mathematics
MATH 101 – Calculus I
Calculus is the elegant language developed to model changes in nature and to formally discuss notions of the infinite and the infinitesimal. Topics include techniques of differentiation, the graphical relationship between a function and its derivatives, applications of the derivative, the Fundamental Theorem of Calculus, and integration by usubstitution. No previous experience with calculus is assumed.

Mathematics
MATH 104 – Calculus II
Calculus II continues the study of integral calculus begun in Calculus I. In addition to the core single variable topics of techniques of integration, applications of the integral, improper integrals, and Taylor series, this course includes the multivariable topics of partial derivatives, optimization of multivariable functions and multiple integrals.

Mathematics
MATH 122 – Math in Art
This course investigates mathematics in the context of some of its myriad connections with the art and architecture of various cultures past and present. Possible mathematical topics include systems of proportion, the development of the Golden Ratio by the ancient Greeks and its connection to Fibonacci numbers, the geometry of perspective, classifying different symmetries, nonEuclidean geometry and the fourth dimension, tessellations, and fractals.

Mathematics
MATH 123 – The Edge of Reason
Consciousness has been memorably described as a flashlight trying to illuminate itself. (Perhaps art is the human activity that best understands the surrounding darkness?) The Edge of Reason is the boundary between light and dark: the mathematics at the border between knowing and notknowing. In this course, we’ll use logic and reason to grapple with ideas and concepts that are literally beyond the reach of human imagination. The Edge of Reason is for anyone interested in understanding the mental models our minds make. While people who enjoy math are encouraged to take the course, the only prerequisites are an open mind, a big mouth and an inquiring spirit. The payoffs are keener analytical abilities, a new way of looking at reality, a penchant for expressing the inexpressible and the ability to tolerate sleep deprivation. An intertwined corequisite is Eng 243 taught by Michael Drout at the same time, on alternating days. This is a yearlong course consisting of one class each semester. By taking both semesters, students will attain the QA and AH designations and also fulfill a twocourse Connections requirement. However, a student may enroll in only The Edge of Reason.

Mathematics
MATH 125 – The Shape of Space
The geometry behind objects in everyday life and the shape of our universe will be investigated. Topics include: symmetry, tilings, patterns, planes, spheres, and higher dimensional surfaces. By adopting the perspective of a bug on a surface, different geometries will be experienced, allowing the students to consider the shape of our universe.

Mathematics
MATH 126 – Math and Pop Culture
Introduces mathematical ideas, by first seeing them mentioned, or used, in a script/text. Examples: Proof, by David Auburn; Breaking the Code, by Hugh Whitemore; Arcadia, by Tom Stoppard; The Simpsons and Numb3rs. Each work at least mentions mathematics, some even provide details. In most cases, the work is not really about, nor does the story depend on, the mathematics. In other cases, the mathematics is crucial to the story. We take the mathematical ideas and learn about the mathematical details, understand them for their own sake and how the ideas fit the original work. Mathematical topics: proof, cryptography, number theory, probability/data analysis. Satisfies QA requirement. No prerequisites.

Mathematics
MATH 127 – Colorful Mathematics
The mathematics behind coloring, drawing and design will be investigated and the art of coloring, drawing and design will aid in the study of other math topics. Topics include: African unicursal tracings, coloring maps, coloring graphs, symmetry, border patterns and tessellations.

Mathematics
MATH 199 – Independent Study
An individual or smallgroup study in mathematics under the direction of an approved advisor. An individual or small group intensively studies a subfield of mathematics not normally taught. An independent study provides an opportunity to go beyond the usual undergraduate curriculum and deeply explore and engage an area of interest. Students are also expected to assume a greater responsibility, in the form of leading discussions and working examples.

Mathematics
MATH 202 – Cryptography
We live in an ocean of information and secrets, surrounded by codes and ciphers. Actions as prosaic as making a call on a cellphone, logging onto a computer, purchasing an item over the Internet, inserting an ATM card at the bank or using a satellite dish for TV reception all involve the digitizing and encrypting of information. Companies with proprietary data and countries with classified information: all kinds of organizations need a way to encode and decrypt their secrets to keep them hidden from prying eyes. This course will develop from scratch the theoretical mathematics necessary to understand current sophisticated cryptosystems, such as the government, industry and Internet standards: the publickey RSA, the DES and the Rijndael codes.

Mathematics
MATH 211 – Discrete Mathematics
Combining the iron rules of logic with an artist’s sensitivity is part of the aesthetics of a mathematical proof. Discrete mathematics is the first course that asks students to create their own rigorous proofs of mathematical truths. Relations and functions, sets, Boolean algebra, combinatorics, graph theory and algorithms are the raw items used to develop this skill.

Mathematics
MATH 212 – Differential Equations
Since the time of Newton, some physical processes of the universe have been accurately modeled by differential equations. Recent advances in mathematics and the invention of computers have allowed the extension of these ideas to complex and chaotic systems. This course uses qualitative, analytic and numeric approaches to understand the longterm behavior of the mathematical models given by differential equations.

Mathematics
MATH 217 – Voting Theory
This course examines the underlying mathematical structures and symmetries of elections to explain why different voting procedures can give dramatically different outcomes even if no one changes their vote. Other topics may include the GibbardSatterthwaite Theorem concerning the manipulation of elections, Arrow’s Impossibility Theorem, measures of voting power, the theory of apportionment, and nonpolitical applications of consensus theory.

Mathematics
MATH 221 – Linear Algebra
How might you draw a 3D image on a 2D screen and then “rotate” it? What are the basic notions behind Google’s original, stupefyingly efficient search engine? After measuring the interacting components of a nation’s economy, can one find an equilibrium? Starting with a simple graph of two lines and their equations, we develop a theory for systems of linear equations that answers questions like those posed here. This theory leads to the study of matrices, vectors, linear transformations and geometric properties for all of the above. We learn what “perpendicular” means in highdimensional spaces and what “stable” means when transforming one linear space into another. Topics also include: matrix algebra, determinants, eigenspaces, orthogonal projections and a theory of vector spaces.

Mathematics
MATH 236 – Multivariable Calculus

Students are also expected to assume a greater responsibility, in the form of leading discussions and working examples.

Mathematics
MATH 301 – Real Analysis
This course takes a rigorous approach to functions of a single real variable to explore many of the subtleties concerning continuous and differentiable functions that are taken for granted in introductory calculus. Much more than simply an advanced treatment of topics from calculus, this course uses beautiful and deep results about topics such as the Cantor set, Fourier series and continuous functions to motivate the rigorous approach.

Mathematics
MATH 302 – Advanced Cryptography
This course is a continuation of Mathematics 202 – Cryptography (MATH 202), Cryptography, that will explore more mathematically sophisticated topics. Possible topics include elliptic curve cryptography, latticebased cryptography, primality testing, the computational complexity of various cryptographics systems, and the relationship between cryptography and privacy in digital communication.

Mathematics
MATH 321 – Abstract Algebra
This course is an introduction to the study of abstract algebra. We begin with sets, and operations on those sets, that satisfy just a few basic properties and deduce many more properties, creating an impressive body of knowledge from just these few initial ideas. We use this approach to focus on structures known as groups. Symmetry, permutation groups, isomorphisms and homorphisms, cosets and factor groups will be covered, as well as an introduction to rings, domains and fields. A secondary focus will be developing the student’s ability to write rigorous and wellcrafted proofs.

Mathematics
MATH 327 – Graph Theory
A graph is a mathematical structure consisting of dots and lines. Graphs serve as mathematical models for many realworld applications: for example, scheduling committee meetings, routing of campus tours and assigning students to dorm rooms. In this course, we study both the theory and the utility of graphs. Offered at the discretion of the department.

Mathematics
MATH 331 – Geometry
