## 2014-2016 COURSE CATALOGUE : MATHEMATICS

Mathematics has always been one of the core subjects of a liberal arts education because it promotes rigorous thinking and problem-solving ability. Many students who major in mathematics go on to graduate school or to work in related professions. For other students, mathematics is popular as a second major or as a minor in combination with another major from any of the Colleges’ academic divisions.

To meet the challenges, opportunities, and responsibilities encountered after graduation, mathematics majors are encouraged to obtain a broad but firm foundation in the discipline. Majors acquire skill in the use of mathematical methods for dealing with problems from a variety of disciplines, and complement these tools with some training in computer science.

The Department of Mathematics and Computer Science offers two disciplinary majors in mathematics (B.A. and B.S.) and a disciplinary minor in mathematics. In addition to the specific courses listed below, other courses may be approved by the department for credit toward a major. To be counted toward the major or minor, all courses must be passed with a grade of C- or better; the department strongly recommends courses be taken on a graded, rather than a credit/ no credit, basis.

MATH 135 **First Steps into Advanced Mathematics** This course emphasizes the process of mathematical reasoning, discovery, and argument. It aims to acquaint students with the nature of mathematics as a creative endeavor, demonstrates the methods and structure of mathematical proof, and focuses on the development of problem-solving skills. Specific topics covered vary from year to year. MATH 135 is required for the major and minor in mathematics. Prerequisite: MATH 131 or permission of the instructor. (*Offered each semester*)

MATH 204 **Linear Algebra** This course is an introduction to the concepts and methods of linear algebra. Among the most important topics are general vector spaces and their subspaces, linear independence, spanning and basis sets, solution space for systems of linear equations, and linear transformations and their matrix representations. It is designed to develop an appreciation for the process of mathematical abstraction and the creation of a mathematical theory. Prerequisites: MATH 131, and MATH 135 strongly suggested, or permission of the instructor. Required for the major in mathematics. (*Offered annually*)

MATH 214 **Applied Linear Algebra** A continuation of linear algebra with an emphasis on applications. Among the important topics are eigenvalues and eigenvectors, diagonalization, and linear programming theory. The course explores how the concepts of linear algebra are applied in various areas, such as, graph theory, game theory, differential equations, Markov chains, and least squares approximation. Prerequisite: MATH 204. (*Offered alternate years*)

MATH 232 **Multivariable Calculus** A study of the concepts and techniques of the calculus of functions of several variables, this course is required for the major in mathematics. Prerequisite: MATH 131. (*Offered annually*)

MATH 237 **Differential Equations** This course is an introduction to the theory, solution techniques, and applications of ordinary differential equations. Models illustrating applications in the physical and social sciences are investigated. The mathematical theory of linear differential equations is explored in depth. Prerequisites: MATH 232 and 204, or permission of the instructor. MATH 204 may be taken concurrently. (*Offered annually*)

MATH 278 **Number Theory** This course couples reason and imagination to consider a number of theoretical problems, some solved and some unsolved. Topics include divisibility, primes, congruences, number theoretic functions, primitive roots, quadratic residues, and quadratic reciprocity, with additional topics selected from perfect numbers, Fermat’s Theorem, sums of squares, and Fibonacci numbers. Prerequisites: MATH 135 and MATH 204, or permission of the instructor. (*Offered alternate years*)

MATH 313 **Graph Theory** A graph is an ordered pair (V, E) where V is a set of elements called vertices and E is a set of unordered pairs of elements of V called edges. This simple definition can be used to model many ideas and applications. While many of the earliest records of graph theory relate to the studies of strategies of games such as chess, mathematicians realized that graph theory is powerful well beyond the realm of recreational activity. In this class, we will begin by exploring the basic structures of graphs including connectivity, subgraphs, isomorphisms and trees. Then we will investigate some of the major results in areas of graph theory such as traversability, coloring and planarity. Course projects may also research other areas such as independence, domination, and matching. Prerequisites: MATH 135 and MATH 204. (*Offered every third year*)
