Goodwin Join Date Oct 2005 Posts 398 Senior Member	Doing it that way produced the wrong answer according to the textbook the school had. That doesn't surprise me - solutions in textbooks are the last thing to be checked (if at all) before publication and the sheer volume of mistakes I regularly see in the dozens of books I have to use depresses me no end.
