Unformatted text preview: 18.03 Problem Set 1 Due by 12:45 P.M., Friday, February 15, 2008, in the boxes at 2-106, next to the Under- graduate Mathematics Office. Part I of each problem set will consist of problems which are either rather routine, or for which solutions are available in the back of the book, or in 18.03 Notes and Exercises , or on the 18.03 Website http://www-math.mit.edu/18.03 as solutions to Recitation Problems. Part II contains more challenging and novel problems. They will be graded with care (Complain if they are not!) and contribute the bulk of the Homework grade. They will help you develop an understanding of the material. Problems in both parts are keyed closely to the lectures, and numbered to match them. Try the problems as soon as you can after the indicated lecture. Most problem sets correspond to four lectures, through the Monday or Wednesday before the set is due. Each problem set is graded out of 100 points. Each day counts 24 points. The grader has 4 points to give or withhold based on neatness and clarity of the answers. (Problem sets 6 and 7 relate to only three lectures, and each day in them counts 32 points.) I encourage collaboration on homework in this course. However, if you do your homework in a group, be sure it works to your advantage rather than against you. Good grades for homework you have not thought through translate to poor grades on exams. You must turn in your own writeups of all problems, and, if you do collaborate, you must write on the front of your solution sheet the names of the students you worked with. Because the solutions will be available immediately after the problem sets are due, no extensions will be possible . I.
