real analysis - Why differentiability implies continuity, but continuity does not imply differentiability?


Why does differentiability implies continuity, but continuity does not imply differentiability?




I am more interested in the part about a continuous function not being differentiable.



Well, all I could find in regards to why continuous functions can not be differentiable were counter- examples...




I just wanted to know if there was a more detailed way of explaining this.
