It's understandable that finding absolute extremum is impossible for a function with restricted boundary conditions. But why does the derivative of similar functions is not zero when the extremum is on the end points?
To be precisely short with my question, why does the derivative gives only the extremum at the interior points within the boundary and not at the points on the boundary?
