prove if f is differentiable and uniformly continuous on (a b) then f ' is unbounded on (a b). Hint : use contradiction
The function can be sqrt of x
so f'(x)=1/2 sqrt x

  • Welcome to MathSE! You are more likely to get a good answer to your question if you follow a few guidelines. In particular, what have you tried so far, and just where are you stuck? This is not a homework-answering site: many of us want to see that you have put significant work into the problem.

    Huh? $x mapsto sqrt{x}$ on $(0,1)$?

  • @MathematicsStudent1122 . Right. The proposition is false. We can even have a strictly monotonic everywhere-differentiable $f:Bbb R to Bbb R$ such that $f'$ is unbounded on $[0,1]$
