Homework #4 is posted. It is longer than normal because it contains problems on new material (1-3) as well as practice problems for Mid-term Examination #1 (4-10). The most effective way to use this homework is to work problems 4-10 as though they were an exam. Do them in a quiet environment and time yourself to assess what you are prepared for and what you should study more. Please feel free to discuss your solutions in office hours. But please remember that understanding our solutions is NOT educationally equivalent to generating your own solutions.

February 23, 2010
Clarification of Homework Grades. Each homework problem will be graded as check (fine), check-plus (very good), check-minus (one or more deficiencies), or zero. Average homework grades on the positive side of check will increase your final grade in 6.003 above the weighted average of your exam grades. Average homework grades on the negative side of check will reduce your final grade in 6.003. Missing homework counts as check-minus-minus-minus.
