* The plan for the use of the Recitation is given here. The student is expected to arrive prepared. Preparation for the discussion sessions consists of a preview of the material, e.g. perusing the text and doing part (a) of each problem. Preparation for the quizzes should consist of having done the homework problems. The homework will not be collected or graded; the recitation quizzes will suffice for our evaluation of your understanding.
**Lecture preview consists of reading the text section indicated before lecture. Doing this will greatly increase the utility of the lecture for you. See notes under Organization below for more on the Assignments, Recitation Quizzes, etc.
