The new book has different examples. This should have been obvious to me. I should have known that that would be the case. But noooo. I've been so busy that I didn't even pull my book out until just now and went WTF. Now I have to prep all new problems.
The truly sad part of all of this is that I'm the department head. I APPROVED THE NEW TEXTBOOK!!!
Oh well, at least I know how I'm spending my weekend.
