Be Careful
Be careful when doing the homework and make sure not to blindly follow the back of the book answers. I have already found a discrepancy between the two that I can only call a typo either in the solution or in the question. (I'd point it out exactly which question I'm talking about but I'm not sure if I can do that, I'm sure you'll find it on your own.)
Feel free to point it out. The most important thing for everybody is to work on the homework and to understand it. It is possible to find answers to all the questions on the web, but doing that would take away the benefit of actually doing the homework. The students who do the homework seriously get the best grades. - Steve Bell
