Homework: It is essential to do mathematics in
order to learn it. Your homework is your responsibility.
Homework assignments are given on the course webpage. I am ready
to answer questions on your homework - mostly during my office
hours (or meetings by appointment). You are strongly recommended
not to miss these opportunities. I encourage you to form study
groups to discuss homework problems. A solution manual is
available from SWEM library, which can be used to check
solutions that you have obtained without its use. Solution for
each homework will also be available from Blackboard site one
week after the assignment.
Calculators: Electrical calculators are not forbidden
but also not encouraged, and students can expect to take most
tests and quizzes without a calculator. TI-83 or TI-84 graphing
calculators (or comparable models) can be used in quizzes; and
exams, and TI-85 or above or calculators on mobile phones cannot
be used in quizzes and exams.
Computer software: Some online programs, applets and
software Matlab will be used for demonstration, and students are
also encouraged to use them for homework. The software are not
needed for quizzes and exams.
Attendance: Regular attendance is critical for your
success in this course. I expect your presence at every lecture.
Grading: Your final grade is calculated as follows:
Mid-term Exam 20% each, 40% total
Final Exam: 40%
The letter grade is assigned using the scale:
A > 93 > A- > 90 > B+ > 87 > B > 83
> B- > 80> C+ > 77 > C > 73 > C- >
70 > D+ > 67 > D > 63 > D- > 60 > F
Honor Code: Students will uphold William and Mary's
stated honor code as it is written, any infractions will be
referred to the Honor Council.
