18.03 Problem Set 8
This is the complete version of PS8. Part II
(iv) has been slightly changed
(correcting a mistake) and renumbered
. Due by 12:45 P.M., Friday, May 2, 2008,
in the boxes at 2-106, next to the Undergraduate Mathematics Oﬃce.
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 will translate to poor grades on exams.
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,
extensions will be possible
