Description

The Department of Mathematics offers courses that promote rigorous thinking in a systematic, deductive, intellectual discipline; present to the student the direction and scope of mathematical development; foster technical competence in mathematics as an aid to the better comprehension of the physical, biological and social sciences guide and direct mathematics majors toward an interest in mathematical research.

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

The Department of Mathematics and Statistics houses the major in mathematics, the minor in mathematics and the minor in statistics, and collaborates with other departments in several concentrations (see below). Mathematics majors take a 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. We urge mathematics majors to gain facility in the use of computers, either through the introductory courses CMSC 105, 106, through applied math electives (like MATH 210, 218, 222 or 397) or through independent work.

Mathematics minors take the same core sequence as do the majors, though not necessarily to the same depth, followed by a selection of electives tailored to the student's interest. Statistics minors take a separate core sequence in probability and statistics, with later flexibility in pursuing either a more applied or a more theoretical track.

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 a 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 listedunder their own headings in this catalog.

Mathematics students (either majors or minors) preparing for a teaching career in mathematics should take one elective in probability and statistics (STAT 203 or MATH 218) and one in geometry or topology (MATH 205 or 335). Students preparing for employment in industry immediately after college should take electives in statistics (STAT 203, 286 or 328) and mathematical modeling (MATH 210 or 222). Students preparing for graduate work in physical chemistry or theoretical physics should take Complex Analysis (MATH 392) and Analysis II (Math 318). Minors desiring a deep understanding of an area of pure math should take 300-level courses in that area (MATH 318 and 392 for analysis, MATH 334 and 390 for algebra and MATH 335 and 337 for geometry and topology).

104 Calculus: Concepts and History NA/QU (Cross-listed in Independent College Programs)

J.Tecosky-Feldman
This is an introduction to the history and development of the ideas of calculus, one of the most beautiful and useful creations of the human intellect.

In addition to regular problem sets, students are required to write essays explaining the important concepts of the course. This course is suitable for students interested in a nontechnical survey of the ideas of calculus. In particular, it does not cover the same amount of material as MATH 113, and students cannot substitute this course for MATH 113 in order to take any course (such as MATH 114) requiring MATH 113 as a prerequisite. Not ordinarily open to students who have studied calculus previously. Offered occasionally.
