On consider where and Is it a metric space?

I think is not, because of the triangle inequality.

What do you guys think?

Haven't found one yet.

But are you implying that it doesn't satisfy the triangle inequality? - Apr 3rd 2011, 05:23 PMDrexel28

Okay, thanks!

Indeed, the triangle inequality fails. Keep looking for a counterexample; it isn't particularly tricky in this case.
