Three words: MEAN VALUE THEOREM

.

Let and you're done.

If , then is said to be Lipschitz continuous, with the Lipschitz constant being the smallest such that satisfies that inequality. Lipschitz continuity always implies uniform continuity, but not necessarily the other way around. - Oct 13th 2009, 07:29 PMJose27
