MATH 170 Single Variable Calculus

The study of real-valued functions, including transcendental functions, limits, derivatives and their applications, the definition of the Riemann integral, and the Fundamental Theorem of Calculus.Three hours of classroom and one and a half hour of lab per week. Prerequisite: 151 or departmental placement. Offered every semester.

MATH 201 Dynamical Systems/Info Theory

In dynamical systems, we study how processes change with time. Real-world examples of dynamical systems include the stock market, the motion of planets and galaxies, population growth and decline, weather systems, and chemical changes. Dynamical systems that are chaotic exhibit some type of unpredictability in their behavior. While topics in dynamical systems have been studied for hundreds of years, the recent development of computer graphics has contributed to a surge of interest and progress in the field. Our focus will be on one-dimensional real dynamical systems and symbolic dynamics.
We will also explore the relationship between dynamical systems and information theory. In particular, we will study ways in which we can code information for efficiency. When you ZIP a file on your computer, you are compressing data, but you expect that you will be able to recover this data later. How can you encode a particular message in a way so that you can both minimize the space needed to store it but also be able to recover the original data? We will see how the how the topics of entropy as well as the Noiseless Coding Theorem help answer these questions.
