faculty and students

Why study mathematics?

Mathematics is perhaps the most intellectually challenging and practical major you can choose. Some major in math for the enjoyment and beauty of the subject. Others major in math for its practicality and applicability to the sciences, engineering, finance, and even the social sciences. Mathematics develops rigorous analytical thinking skills that are prized in all fields of human endeavor.

What are these classes?

MATH 1342 Introduction to Probability and Statistics: This course acts mainly as a service course for other disciplines; however, many mathematics students take this course early in their college career. This course provides an introduction to modeling random phenomenon using probability and an introduction to the analysis of data using statistics.

MATH 2313, 2113, 2314, 2114, 3315, 3115 The Calculus Sequence: A traditional three-course calculus sequence with lab component is the foundation of our major. Some students may want to prepare for calculus by taking Pre-calculus, MATH 2211 and 2212.

MATH 3320 Introduction to Numerical Methods: Numerical Methods is another of our courses that introduces and explores how mathematical problems are solved in careers in industry. Some instructors use graphing calculators for programming experience and others encourage the use of programming languages to write code for approximation of roots of functions, numerical integration and curve-fitting.

MATH 3325 Computational Linear Algebra: The tools of linear algebra are the heart of many mathematical descriptions in science and engineering. In this course, we explore the fundamental tools of linear algebra while focusing on applications within the context of engineering, physics, and computer science. This class was designed for other majors who get a math minor; math majors will take MATH 3365 instead.

MATH 3330 Differential Equations: This course introduces methods of solving differential equations that arise in various applications in physics, chemistry and engineering. Differential equations give a glimpse of how mathematics might be used in careers in industry.

MATH 3340 Probability Modeling: This course is a calculus based introduction to constructing models for the uncertainty that persists in the natural world. The course provides an introduction to probability laws, random variables and the concept of distributions. These distributions along with other specific random processes provide the foundation for applied probability as well as prepare the student for additional courses in statistics.

MATH 3345 Statistical Inference: The focus of MATH 3345 is the statistical process by which conclusions about populations can be inferred from data collected on samples.  This calculus based statistics course provides both the mathematical underpinning of estimation and hypothesis testing while also being sufficiently data-driven and application oriented.  Appropriate technology which enhances the ability to analyze data is included throughout.

MATH 3360 Introduction to Modern Mathematics: This course is a formal introduction to logic and proof, giving practice writing rigorous mathematics and a preview of how to think like a mathematician.

MATH 3365 Linear Algebra: While Linear Algebra is another proof-based course, the theory of linear systems, matrices, determinants and other topics in the course supports many of our applied mathematics courses and statistics courses. Computational linear algebra is used in other disciplines—chemistry, physics, biology—as well.

MATH 3370 College Geometry: College Geometry is another must-have course for those who plan to teach in secondary schools. The course provides a survey of topics from classical and modern Euclidean geometry, transformational geometry, as well as some non-Euclidean geometry. Geometry leans heavily on the logic and proof practice that the student starts in MATH 3360.

MATH 4320 Introduction to Algebraic Systems: Usually referred to as Abstract Algebra, this course introduces the student to algebraic structures such as groups, rings, and fields. Abstract Algebra it is a must-have course for those who will teach in secondary schools to realize the basis for high school algebra. Students will exercise the skills they learned in MATH 3360 since MATH 4320 is a proof-based course.

MATH 4325 Number Theory: This course includes a rich survey of topics in number theory including applications of modular arithmetic, Diophantine equations, and studies of primes. It is a natural course to come right after or concurrently with abstract algebra, as it is very much proof-based, but the only prerequisite is MATH 3360; students can take it early in their sequence of courses.

MATH 4330, 4335 Introduction to Analysis I and II: This sequence serves somewhat as a capstone experience for our majors. The students revisit topics discussed in the calculus sequence, but with a greater degree of rigor and depth. Many of our students feel that these are the courses that crowned their mathematical maturity.

MATH 4180 Seminar in Mathematics: This seminar provides students with a survey of the tools and skills useful in advanced mathematics, including technical writing and oral presentation, mathematical pedagogy, computer algebra and electronic presentation systems, history of mathematics, professional organizations and their functions, and preparation for careers in mathematics or graduate school.

...and the statistics classes...

STAT 3342 Statistical Methods: As a second course in statistics, STAT 3342 gives a three-pronged introduction to the following areas of statistics: analysis of variance, regression, and nonparametric methods. This course makes use of a statistical computing package in order to analyze data sets. The techniques covered in this course, as well as STAT 3344, 3346, and 3348, all have applications in business, industry, agriculture, forestry, biomedical science, psychology, and sociology, among others.

STAT 3344 Applied Nonparametric Statistics: The statistical methods used in this course are very useful in attacking problems that cannot be solved using standard parametric procedures as introduced in MATH 1342 and STAT 3342.

STAT 3346 Statistical Modeling: Of interest in this course is finding a mathematical relationship between two or more variables. The discovery and verification of such a relationship is accomplished by analyzing a data set with a statistical computing package.

STAT 3348 Experimental Design and Analysis: STAT 3348 extends some of the statistical methods introduced in STAT 3342. This course deals with setting up an appropriate experimental design in order to answer questions on how some treatment affects a particular variable.

What can a major in mathematics do for me?

Studying mathematics develops such skills as arguing logically and rigorously, thinking abstractly, formulating and solving problems, analyzing data, and creating and analyzing mathematical models. Employers value these skills; consequently, math majors find themselves in demand by employers for careers in a wide spectrum of fields.

A study of college students' scores on admission tests for graduate and professional schools (LSAT and GMAT) showed that students majoring in mathematics received scores substantially higher than the average on each of the tests studied. In addition, math majors can expect to earn more and have a higher job satisfaction rating than other majors. Check it out at!
