Consider this

yes, it is.

let's break that set into

note that the first set is compact, so is automatically uniformly continuous there, but as for the second set, for each is and this satisfies Lipschitz condition, hence we have uniform continuity on the second set, and finally on the whole set. - October 25th 2009, 07:09 PMrn443
