TR 11:30a - 12:45p: South 336

This course, which is intended for the
mathematics major who is enrolled in the secondary education
program,provides a bridge and establishes connections between the college
level
mathematics required of the mathematics major and the mathematics of the
secondary school curriculum.

MATHEMATICS 348

Oral Presentation & Research Seminar

MF 2:30 - 3:20p: South 336

This is a most unusual mathematics
class, in that you are not responsible for learning any
mathematics. You will be
preparing a library research project on a topic in mathematics and
presenting several presentations to the class. We will also
discuss several issues related to these performance outcomes.
These may include some of the following: typesetting in
mathematics,
bibliographic references in mathematics, and talk styles in
mathematics. This class is about producing products
and not about learning mathematics.

MATHEMATICS 381

Topics in Mathematics: Galois Theory

MWF 12:30 - 1:20p: Sturges 103

Prerequisite: Math. 330

MWF 12:30 - 1:20p: Sturges 103

Prerequisite: Math. 330

In this course we will explore the question of
solvability of polynomials. We will consider finding and permuting
roots from Galois’ original historical
perspective. Along the way we will settle some of the classical
construction problems and see the power of applying seemingly
theoretical ideas to the more practical question of finding roots of
polynomials.
