@Math1000 In the last two displayed equations, shouldn't $x$ be $w$? If not, then I think there is a conflict between your answer and that of Andre Nicolas?

@Student T Thanks. If you could give me a link or two to the "tons of material online" I'd appreciate it. My own googling has turned up little (beyond wikipedia).
