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 P. Fletcher and C. W.
Patty, Foundations of Higher Mathematics, 3rd ed., (Pacific

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.
