This course does not satisfy the Math GER.
Description: This course was designed for math
majors as a
bridge between the lower level problem solving courses (calculus and
differential
equations) and the required upper level proof-based courses (MA 407 and MA 425). In MA 225 the course
content includes
the basic proof techniques and the logical basis of those proof
techniques as well
as the special technique of math induction. In addition, we go over
relations and
equivalence relations, functions and cardinality which are all topics
that will be
needed in later courses. More importantly, the student is expected to
begin to think
mathematically and to write proofs and problem explanations in a clear,
concise and
logical fashion.

Late homework will not be graded.
Attendance is expected in all classes.
Students who miss 3 or fewer classes may count their lowest test
as half a test.
If you miss a test, I will
need a letter documenting the reason. Makeup tests can only be given
for reasons such as illness, family emergency, participation in a
University-sponsored event, required court attendance or military duty,
or religious observances as certified by the Department of Student
Development.
If you know you will be absent on a test date, you must clear the absence with me in advance and schedule a makeup date. In the case of an unanticipated absence on a test date, you must give me documentation and schedule a makeup date as soon as possible. See the University policies.
NCSU policy, including what constitutes an 'Excused Absence,' is at this link.
Students are required to follow NCSU policy available at www.ncsu.edu/provost/academic_regulations/integrity/reg.htm. "Academic dishonesty is the giving, taking, or presenting of information or material by a student that unethically or fraudulently aids oneself or another on any work which is to be considered in the determination of a grade or the completion of academic requirements or the enhancement of that student's record or academic career." (NCSU Code of Student Conduct)
The Student Affairs web site has more information (http://www.ncsu.edu/student_affairs/osc/AIpage/acaintegrity.html).
"I have neither given nor received unauthorized aid on this test or assignment."
This has been outlined above
