Do you know what sylabus it comes from? Commonly these days professors have their sylabus on line. If you know the course number and the university you can likely find it. If you are at the university itself blackboard almost always has this, going back years.
Actually these exercises were from an exam, and I could not find the book in the syllabus. I could not even find anything similar in the Internet, I tried google and also books.google.com, but I'm sure that the exercises come from some textbook, I mean they were not edited by the professor.
