The book defines it fine. But what I was looking for was an explanation for what possible use the definition might have. Any math book should say *why* a definition is introduced, not just what it is. That's important for motivation, and also for explanation. Otherwise, the definition is just an arbitrary set of conditions. I can define things too, any way I want. And when you see a zillion definitions in a math book, how are you to know which ones matter and which ones are hardly ever used? <br /> <br /> ------</div>
