MATH 105 and 106 are designed for students whose background and algebraic skills are inadequate for the fast pace of MATH 111. In addition to covering the usual material of beginning calculus, these courses will have an extensive review of algebra and trigonometry. There will be a special emphasis on solving word problems.

MATH 105 starts with a quick review of algebraic manipulations, inequalities, absolute values and straight lines. Then the basic ideas of calculus--limits, derivatives, and integrals--are introduced, but only in the context of polynomial and rational functions. As various applications are studied, the algebraic techniques involved will be reviewed in more detail. When covering related rates and maximum-minimum problems, time will be spent learning how to approach, analyze and solve word problems. Four class hours per week.

Note: While MATH 105 and 106 are sufficient for any course with a MATH 111 requisite, MATH 105 alone is not. However, students who plan to take MATH 121 should consider taking MATH 105 and then MATH 111, rather than MATH 106. Students cannot register for both MATH 105 and CHEM 111 in the same semester.

Fall semester. Professor Cox.

MATH 106 is a continuation of MATH 105. Trigonometric, logarithmic and exponential functions will be studied from the point of view of both algebra and calculus. The applications encountered in MATH 105 will reappear in problems involving these new functions. The basic ideas and theorems of calculus will be reviewed in detail, with more attention being paid to rigor. Four class hours per week.

Requisite: MATH 105. Spring semester. Professor Cox.

Basic concepts of limits, derivatives, anti-derivatives; applications, including max/min problems and related rates; the definite integral, simple applications; trigonometric functions; logarithms and exponential functions. Four class hours per week.

(Offered as MATH 130 and ENST 240.) This course is an introduction to applied statistical methods useful for the analysis of data from all fields. Brief coverage of data summary and graphical techniques will be followed by elementary probability, sampling distributions, the central limit theorem and statistical inference. Inference procedures include confidence intervals and hypothesis testing for both means and proportions, the chi-square test, simple linear regression, and a brief introduction to analysis of variance (ANOVA). Some sections of MATH 130 have an environmental theme and are recommended for students interested in Environmental Studies. In Fall 2011, the environmental section will be section 02; in Spring 2012, there will NOT BE an environmental section. Four class hours per week (two will be held in the computer lab). Labs are not interchangeable between sections due to course content.

Each section limited to 20 students. Fall semester: Professor Liao and Postdoctoral Fellow Stratton. Spring semester: Professor Manack and Postdoctoral Fellow Stratton.

Mathematical modeling is the process of translating a real world problem into a mathematical expression, analyzing it using mathematical tools and numerical simulations, and then interpreting the results in the context of the original problem. Discussion of basic modeling principles and case studies will be followed by several projects from areas such as environmental studies and biology (e.g., air pollution, ground water flow, populations of interacting species, social networks). This course has no requisites; projects will be tailored to each student’s level of mathematical preparation. Four class hours per week, with occasional in-class computer labs.

Omitted 2011-12.

This course is an intermediate applied statistics course that continues the theme of hands-on data analysis begun in MATH 130. Students will learn how to evaluate an experimental study, perform appropriate statistical analysis of the data, and properly communicate their analyses. Emphasis will be placed on the use of statistical software and the interpretation of the results of data analysis. Topics covered will include basic experimental design, parametric and nonparametric methods for comparing two or more population means, analysis of variance models for multi-factor designs, multiple regression, analysis of covariance, model selection, logistic regression, and methods for analyzing various types of count data.

In Euclidean geometry, the parallel axiom asserts that if we have a line and a point not on the line, then there is a unique line through the point which is parallel to the given line. This seemingly obvious statement has many consequences, including the Pythagorean Theorem and the fact that the angles of a triangle sum to 180 degrees. In the nineteenth century, it was discovered that this is not the only possible geometry. The course will begin with neutral geometry, which makes no assumptions about parallel lines. We will then study non-Euclidean geometry, which uses a different parallel axiom. Familiar objects like circles and triangles behave differently in this geometry. For example, rectangles don't exist, and the angles of a triangle sum to less than 180 degrees, and the difference is proportional to the area of the triangle. This will allow us to construct an eight-sided house where every corner is a right angle. Besides proving some fun theorems, we will also study the history of non-Euclidean geometry. The final part of the course will be an introduction to differential geometry. The key concepts will be geodesics (which generalize straight lines) and curvature (which measures how the space is warped). This will allow us to make models of non-Euclidean geometry and explore how geometric ideas apply in a much wider context. Four class hours per week.

Requisite: Math 211 or consent of the instructor. Fall semester. Professor Cox.

The study of differential equations is an important part of mathematics that involves many topics, both theoretical and practical. The precise subject matter of this course will vary from year to year.

Three class hours per week plus a weekly one-hour computer laboratory.

Requisite: MATH 211 and 271 or 272. Fall semester. Professor Leise.

Real world experiments often provide data that consist of many variables. When confronted with a large number of variables, there may be many different directions to proceed, but the direction chosen is ultimately based on the question(s) being asked. In biology, one could ask which observed characteristics distinguish females from males in a given species. In archeology, one could examine how the observed characteristics of pottery relate to their location on the site, look for clusters of similar pottery types, and gain valuable information about the location of markets or religious centers in relation to residential housing. This course will explore how to visualize large data sets and study a variety of methods to analyze them. Methods covered include principal components analysis, factor analysis, classification techniques (discriminant analysis and classification trees) and clustering techniques. This course will feature hands-on data analysis in weekly computer labs, emphasizing application over theory. Four class hours per week.

Limited to 20 students. Omitted 2011-12.

This course explores the nature of probability and its use in modeling real world phenomena. The course begins with the development of an intuitive feel for probabilistic thinking, based on the simple yet subtle idea of counting. It then evolves toward the rigorous study of discrete and continuous probability spaces, independence, conditional probability, expectation, and variance. Distributions covered include the Bernoulli and Binomial, Hypergeometric, Poisson, Normal, Gamma, Beta, Multinomial, and bivariate Normal. Four class hours per week.

Requisite: MATH 121 or consent of the instructor. Fall semester. Professor Liao.

In mathematics, a group is a mathematical structure that is commonly found in nature, particularly in the context of symmetries of a physical system. In Representation Theory we study groups via something very concrete: matrices. This rich subject has applications to chemistry, physics, and almost every branch of mathematics. In this course we will learn enough of the fundamentals to explore some applications to molecular vibrations.

Requesite: Math 350 or consent of the instructor. Spring semester. Visiting Professor Torrey.

Most mathematicians consider set theory to be the foundation of mathematics, because everything that is studied in mathematics can be defined in terms of the concepts of set theory, and all the theorems of mathematics can be proven from the axioms of set theory. This course will begin with the axiomatization of set theory that was developed by Ernst Zermelo and Abraham Fraenkel in the early part of the twentieth century. We will then see how all of the number systems used in mathematics are defined in set theory, and how the fundamental properties of these number systems can be proven from the Zermelo-Fraenkel axioms. Other topics will include the axiom of choice, infinite cardinal and ordinal numbers, and models of set theory. Four class hours per week.

Requisite: MATH 220, 271, 272, or 355, or consent of the instructor. Omitted 2011-12.

Mathematicians confirm their answers to mathematical questions by writing proofs. But what, exactly, is a proof? This course begins with a precise definition specifying what counts as a mathematical proof. This definition makes it possible to carry out a mathematical study of what can be accomplished by means of deductive reasoning and, perhaps more interestingly, what cannot be accomplished. Topics will include the propositional and predicate calculi, completeness, compactness, and decidability. At the end of the course we will study Gödel’s famous Incompleteness Theorem, which shows that there are statements about the positive integers that are true but impossible to prove. Four class hours per week. Offered in alternate years.

Requisite: MATH 220, 271, 272, or 355, or consent of the instructor. Omitted 2011-12.
