Continuity and Uniform Continuity

It is obvious that a uniformly continuous function is continuous if we can nd a which works for all x 0, we can nd one the same one which works for any particular x 0 We will see below that there are continuous functions which are not uniformly continuous Example 5 Let S= R and f x = 3x 7 Then fis uniformly continuous on S Proof ....Know More

Differentiable and uniformly continuous? Physics Forums

Nov 10, 2008 0183 32 Intuitively, if f is differentiable it is continuous If its derivative is bounded it cannot change fast enough to break continuity The interval is bounded, and the function must be bounded on the open interval It seems that there is not way that the function cannot be uniformly continuous But ....Know More
