Mathematics Department

AP: Students receiving one unit of AP credit based on either the AB or BC Mathematics AP Examination or the calculus credit examination administered by the Department of Mathematics may not be granted credit for MATH 121. Students receiving one unit of AP credit based on the Statistics AP Examination may not be granted credit for MATH 141.

Advanced Course Placement: The department recommends that students who have earned a 4 or 5 on the BC examination enroll in  MATH 220. Students with a 5 on the AB examination or a 3 on the BC examination generally are advised to elect MATH 220 also, after conferring with the department. Students with a 4 on the AB examination ordinarily are advised to enroll in MATH 127 but should consult with the department.

Material from MATH 121/MATH 122 presented in one semester for students with previous experience with calculus. Topics in second semester calculus are fully developed and topics in first semester calculus are reviewed.

Three 50-minute periods.

126a and b. Calculus IIA: Integration Theory (0.5)

In this course, we expand and build upon basic knowledge of differential and integral calculus. Various techniques and applications of integration will be studied. The calculus of transcendental functions---such as the exponential, logarithmic, and inverse trigonometric functions---will also be developed. A main theme in this course is the many ways functions can be defined, and arise naturally in problems in the mathematical sciences.

Prerequisite: MATH 121 or its equivalent.

First or second six-week course.

127a and b. Calculus IIB: Sequences and Series (0.5)

Real numbers may be represented as infinite decimals. In this course we generalize this representation by studying the convergence of sequences and of series of real numbers. These notions further generalize to the convergence of sequences and series of functions. We study these ideas and their relation to the Calculus.

Prerequisite: MATH 121 or its equivalent.

First or second six-week course.

131a. Numbers, Shape, Chance, and Change (1)

What is the stuff of mathematics? What do mathematicians do? Fundamental concepts from arithmetic, geometry, probability, and the calculus are explored, emphasizing the relations among these diverse areas, their internal logic, their beauty, and how they come together to form a unified discipline. As a counterpoint, we also discuss the "unreasonable effectiveness" of mathematics in describing a stunning range of phenomena from the natural and social worlds. The department.

Prerequisites: at least three years of high school mathematics.

Open only to freshmen; satisfies the college requirement for a Freshman Writing Seminar.

Two 50-minute periods and one 50-minute discussion period.

132a. Mathematics and Narrative (1)

To most, mathematics and narrative live in opposition-narrative is ubiquitous while mathematics is perceived as inscrutably esoteric and obscure. In fact, narrative is a fundamental part of mathematics. Mathematical proofs, problems and solutions, textbooks, and journal articles tell some sort of story. Conversely, many literary works (Arcadia, Proof, and Uncle Petros and the Goldbach Conjecture) use mathematics as an integral part of their narrative. Movie and television narratives such as Good Will Hunting and Numb3rs are also mathematically based. Nonfiction works about mathematics and mathematical biographies like Chaos, Fermat's Enigma, and A Beautiful Mind provide further examples of the connection between mathematics and narrative. We use this course to explore this connection by reading and writing a variety of mathematical narratives. 

Open only to freshmen; satisfies college requirement for a Freshman Writing Seminar.

Not offered in 2015/16.

141a and b. Introduction to Statistics (1)

(Same as BIOL 141) The purpose of this course is to develop an appreciation and understanding of the exploration and interpretation of data. Topics include display and summary of data, introductory probability, fundamental issues of study design, and inferential methods including confidence interval estimation and hypothesis testing. Applications and examples are drawn from a wide variety of disciplines. When cross-listed with biology, examples will be drawn primarily from biology.

Prerequisite: three years of high school mathematics.

Not open to students with AP credit in statistics or students who have completed ECON 209 or PSYC 200.

142a. Statistical Sleuthing: Personal and Public Policy Decision-Making in a World of Numbers (1)

The world inundates us with numbers and pictures intended to persuade us towards certain beliefs about our health, public policy, or even which brand of product to buy. How can we make informed decisions in this context? The goal of this course is for us to become statistical sleuths who critically read and summarize a piece of statistical evidence. We read articles from a variety of sources, while using basic statistical principles to guide us. Course format: mixture of discussion and lecture, with regular reading and writing assignments. The department.

Open only to freshmen; satisfies the college requirement for a Freshman Writing Seminar.

Three 50-minute periods.
