I'm kinda stuck on this problem. Would someone give me a hand? Suppose is differentiable and is differentiable at . Show that Is there a function that satisfies this limit but is not differentiable at ?

For the function... (1) ... in the limit exists and it is equal to 0 but its derivative is not differenziable in that point... Kind regards
