Division of Science and Mathematics

The Mathematics Program seeks to give students an understanding and appreciation of the beauty and utility of mathematics. Quantitative and analytic skills are increasingly important in economics, biology, and the social sciences, as well as in the physical sciences and engineering. The study of mathematics at Centre provides the opportunity for the development of clear, logical, and creative thinking that may be applied to a wide variety of problems and interests. In addition to these important problem-solving skills, the mathematics major will learn to present concise, logical arguments in writing and orally. Emphasis is placed on mathematical thinking and precise communication of these thoughts.

Students completing the mathematics major at Centre have a broad range of interests. Many also complete a major in another field. For example, recent mathematics majors have second majors in chemistry, computer science, economics, English, history, physics, and Spanish. Some majors earn secondary teacher certification. Our graduates often decide to continue their academic studies, entering law school, medical school, engineering programs, and M.B.A. programs, as well as graduate school programs in a wide variety of disciplines. Others choose to join the workforce immediately, taking jobs with companies and agencies such as the Census Bureau, the military services, computer companies, public or private schools, and financial institutions. Our students find that the problem-solving and communication skills learned in the mathematics major serve them well in whatever career paths they follow.

Prerequisite: MAT 141 or 170 or permission of the instructor.

MAT 210 Mathematics in the Elementary School
A study of the language and structure of mathematics including problem solving, set and number theory, integers, rational and real numbers, probability and statistics, and geometry. NOTE: This course is open to early elementary education majors only.

MAT 230 Calculus-III
An extension of the concepts of function, limit, derivative, and integral to three-dimensional space and vector spaces; the course describes many applications and their historical significance, such as planetary motion and magnetic fields. Topics include vector algebra, elementary differential geometry of curves and surfaces, limits, continuity, partial derivatives, directional derivatives, multiple integrals, line integrals, surface integrals, Green's Theorem, Stokes' Theorem, and the Divergence Theorem. Prerequisite: MAT 171 or placement.
