You might want to tell the professor. In some of my upper level physics classes we were encouraged to use any means we could find to help us. What the professor was unaware of is that often times you can just type a problem into google and find a solution to it or a similar problem that can be reworked (my speciality). AFAIK, this was okay. However, one of the students found scanned pages of the solution manual which the teacher saw and blew up about. I'm not sure what the difference was, but he ended up calling the other professor to complain. Also I think the bookmaker since this is a huge trademark violation.
