COURSE DESCRIPTION
WHAT IS MATH 109? This course is an
introduction to mathematical reasoning. Perhaps the most useful
consequence of studying mathematics is an enhanced ability to analyze
problems, mathematical or otherwise, logically. In advanced mathematics
courses and in mathematics research, this ability is deployed primarily
to prove that specific statements are true. The goal of this course is
to give the students an understanding of what it
means to do mathematics beyond simply doing calculations. This
includes learning
what kinds of statements need proof, what constitutes a proof, and how
to
read and write proofs.
TEXT: PETER J. ECCLES, An Introduction to Mathematical Reasoning. Cambridge Univ. Press, 1997. You
are expected to read the text BEFORE each lecture.

GETTING HELP
Help with mathematical problems:
 Section: Ask
questions in section  this is one of the main reasons why sections
exist.
 Office Hours: You
are strongly advised to take full advantage of your professor's and
ta's office
hours.
 Classmates: Sometimes
a classmate can help. Sometimes you can learn by working out problems
together with your classmates.
Help with personal problems which
affect your class work:
 Talk to the professor or, if appropriate, your
college provost.
