Mathematics has always held a central position in the liberal arts, and over time, it has also come to play an important role in more and more aspects of our lives. Mathematical analysis and modeling are involved in many areas far beyond the traditional association of mathematics with the physical sciences and engineering. This fact is reflected in the diversity of the students who study at least some mathematics during their time at Washington University — students who recognize the importance of quantitative skills in a world that is becoming more and more technological.

Students major in mathematics for many reasons. Some are planning academic careers in mathematics that involve teaching or research. Others plan to work as actuaries or at other jobs in industry or government. Some plan careers in secondary education. Many majors do not intend to become "mathematicians" at all but simply realize that quantitative training is a valuable asset in many kinds of careers; often, work in mathematics is meant to complement their study in other areas. Other majors view mathematics as an interesting concentration in their liberal arts education, even though they plan to enter professional fields such as medicine or law.

The Mathematics program gives majors and minors a broad introduction to the subject. To fit students' varying academic interests and professional goals, the department offers majors in Mathematics, Applied Mathematics, and Mathematical Sciences, along with two dual majors in Mathematics and Computer Science and in Mathematics and Economics. Majors are encouraged to complete additional work (perhaps even a minor or a second major) in other related areas.

MATH 1010 Foundations for Calculus

A limited enrollment class for students planning to take calculus but who need additional precalculus preparation. The course aims to build both the technical skills and the conceptual understanding needed to succeed in calculus. Course emphasizes links between the graphical, numeric, and algebraic viewpoints. A variety of approaches are used to present the material. Prerequisites: 2 years of high school algebra and a course in geometry (or the equivalent).

Credit 3 units. A&S IQ: NSM

Typical periods offered: Fall, Summer


MATH 1510 Calculus I

Derivatives of algebraic, trigonometric, and transcendental functions, techniques of differentiation, Mean Value Theorem, applications of the derivative. The definite integral and Fundamental Theorem of Calculus. Areas. Simpler integration techniques. Prerequisites: high school algebra and precalculus, including trigonometry.

Typical periods offered: Fall, Spring, Summer


MATH 1513 Peer-Led Team Learning: Calculus I

In this course, student groups meet weekly and work together on a problem set that builds on topics covered in MATH 1510 - Calculus I. The purpose of the course is to encourage students to work in small groups, supervised by a trained peer leader, on problems that require a collaborative effort and are designed to enhance understanding. PLTL sessions guide students to become conscious of the problem-solving process and to rigorously evaluate and revise those processes by considering the reasonableness of their results, rather than by consulting an answer key. Sign-ups for PLTL begin in the first week of the semester, with meetings starting on the weekend following the second week of classes. Grading is Pass/Fail based on participation. Students must attend at least eight sessions during the semester to earn credit; those who do not meet the attendance threshold will be dropped from the course, and the course will be removed from their transcript. To receive credit for PLTL, a student must remain enrolled in the parent course (MATH 1510). Please note the following exceptions to the enrollment and drop policy: (1) Students will not be able to enroll in PLTL if doing so would bring them above 21 credit units, but they will still be able to participate. (2) Students who wish to participate in PLTL but want to opt out of receiving credit should contact their course’s PLTL program manager. (3) If dropping PLTL would bring a student below 12 credit units, the drop will instead be entered as a withdrawal.

MATH 4493 Topics in Graph Theory

Analytic combinatorics is the study of counting sequemces associated to combinatorial configurations and breaks up into two complementary components. First, we systematically encode and study counting problems through the use of power series (generating functions). Second, the analytic properties of these power series are used to understand the growth of counting sequences. Some examples are counting structured strings, functions, permutations, trees, and lattice paths. The principal analytic technique will be complex analysis and the course will include a user's self-contained introduction to complex analysis. Time permitting, we may study counting problems with parameters which naturally leads to multivariable generating functions and allows us to investigate statistical properties of counting sequences.
