The instructor welcomes cooperation among students and the use of books.
However, handing in homework that makes use of other people's work (be it from a fellow
student, a book or paper, or whatever) **without** explicit
acknowledgement is considered academic misconduct.

All homework problems are from the 4th edition of Friedberg et al.
