If a function is countinous on the closed interval and diffrenciable on the open interval . Then is countinous on the closed interval . It seems true, I was not able to find any counterexamples.

I may have the wrong end of the stick here but what about:

"Wrong end of the stick" is that supposed to be a pun
Well, it is true that the endpoint is not countinous (end of stick) okay thus, what about the open interval?

Not sure what you mean. It's a counter example; its continuous on a closed
interval , differentiable on , but its derivative is not continuous
on .
