## COURSE CATALOGUE : MATHEMATICS

*In the Department of Mathematics and Computer Science*

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 majors in mathematics (B.A. and B.S.), and a minor in mathematics. In addition to the specific courses listed below, other courses may be approved by the department for credit toward the major. To be counted toward the major or minor, all courses must be passed with a grade of C- or better; credit/no credit courses cannot be taken toward the major or minor.

**REQUIREMENTS FOR THE MAJOR (B.A.) **

*disciplinary, 11 courses*

MATH 135, MATH 204, and MATH 232; CPSC 124; either MATH 331 or MATH 375; MATH 471; two additional mathematics courses at the 200-level or above; one additional mathematics courses at the 300-level or above; and two additional courses chosen from mathematics (MATH 131 and above) and computer science (CPSC 220 and above). Completion of an honors project and presentation of the thesis at the Senior Symposium may be substituted for MATH 471.

**REQUIREMENTS FOR THE MAJOR (B.S.) **

**COURSE DESCRIPTIONS**

**MATH**** 100** **Elementary Functions** Intended for students who plan to continue in the calculus sequence, this course involves the study of basic functions: polynomial, rational, exponential, logarithmic, and trigonometric. Topics include a review of the real number system, equations and inequalities, graphing techniques, and applications of functions. A problem-solving lab is an integral part of the course. Permission of instructor is required. This course does not count toward the major or minor in mathematics. (*Offered annually*)

**MATH**** 110** **Discovering in Mathematics** A study of selected topics dealing with the nature of mathematics, this course has an emphasis on the origins of mathematics, and a focus on mathematics as a creative endeavor. This course does not count toward the major or minor in mathematics. (*Offered each semester*)

**MATH**** 114** **Mathematics for Informed Citizenship** This course explores the uses and abuses of numbers in a wide variety of areas. The modern world is built of numbers. In science, medicine, business, politics, and even culture, numbers are used to bolster claims and debunk conventional wisdom. A deeper understanding of the mathematics behind these arguments can help us determine what to trust and when to doubt, teach us how to weigh the risks versus rewards, and allow us to come to grips with the vast scale of the universe and the national debt. Mathematical topics will include randomness, basic statistics, linear regression, inference and nonlinearity. An emphasis is placed on critical engagement with numerical evidence and mathematical thinking as deployed in the culture at large. The course has a significant writing component.

**MATH**** 115** **Foundations of School Mathematics** Students will study the mathematical foundations of elementary school mathematics. This course will develop a student's abilities to reason mathematically, to solve mathematical problems, and to communicate mathematical ideas effectively. Primary attention will be devoted to mathematical reasoning in areas drawn from number systems and algebraic structures, number theory, algebra and geometry, probability and statistics, and discrete mathematics. Students will gain a deeper understanding of the nature and structure of mathematics, and more specifically of how elementary school mathematics is embedded within the broader discipline of mathematics. Prerequisite: must be in the Teacher Education Program pursuing certification to teach in an elementary school setting. (*Offered alternate years*)

**MATH**** 130 Calculus I** This course offers a standard introduction to the concepts and techniques of the differential calculus of functions of one variable.

**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.
