DescriptionFacultyMajor RequirementsMinor RequirementsRequirements for HonorsCoursesDepartment Homepage


The aims of courses in mathematics are: (1) to promote rigorous thinking in a systematic, deductive, intellectual discipline; (2) to present to the student the direction and scope of mathematical development; (3) to foster technical competence in mathematics as an aid to the better comprehension of the physical, biological, and social sciences; and (4) to guide and direct the mathematics majors toward an interest in mathematical research.

Mathematics majors take a three-year core sequence of courses in calculus, linear algebra, abstract algebra and analysis, designed to provide a foundation for further study in the major areas of modern mathematics. Students with substantial advanced placement may complete this sequence by the end of their sophomore year. Students who have completed the core sequence may take advanced courses in algebra, analysis, topology or other special topics.

The department offers several intermediate-level courses designed for both majors and non-majors. These include Mathematics 121 and 215-216, which provide an important foundation for more advanced work in mathematics and other sciences. Mathematics 113, 114 and 115 (or equivalent advanced placement) is sufficient background for any of these courses. A program including Mathematics 113, 114, 203, 210, 215 and 286 is especially appropriate for majors in the social sciences. Students planning graduate study in economics should consider taking Mathematics 317.

Mathematics majors are urged to gain facility in the use of computers, either through the introductory courses Computer Science 105, 106, through applied math electives (like Math 210, 218, 222 or 397) or through independent work. Students interested in pursuing computer science in depth as part of a mathematics major should consider the possibility of a concentration in computer science or in scientific computing (the former being more theoretical, and the latter more applied). Mathematics majors interested in applying their skills to economic problems have the option of pursuing an area of concentration in mathematical economics. Students interested in teaching mathematics can concentrate in educational studies. The requirements for concentrations in computer science, scientific computing, mathematical economics and educational studies are described under their own headings in this catalog.

Mathematics minors preparing for a mathematics teaching career should take one elective in probability and statistics (Mathematics 203 or 218) and one in geometry or topology (Mathematics 205 or 335). Minors preparing for employment in industry immediately after college should take electives in statistics (Mathematics 203 or 286) and mathematical modeling (Mathematics 210 or 222). Minors preparing for graduate work in physical chemistry or theoretical physics should take Complex Analysis (Mathematics 392) and Analysis II (Mathematics 318). Minors desiring a deep understanding of an area of pure math should take 300 level courses in that area (Mathematics 318 and 392 for analysis, Mathematics 334 and 390 for algebra, Mathematics 335 and 336 for topology).
