# Not differentiable; continuous [duplicate]

I know that there are functions which are continuous but not differentiable, but are there functions which are not continuous, but differentiable?

The differrentiablility is stronger than continuity hence the answer is: no. However your question is not naive: function can have partial derivatives but be noncontinuous in a chosen point.
