This paper proposes a new method of seeking the derivation of a fragmental function at the point of demarcation. The application of the method must consider two preconditions, which one is that the function is continuous at the point of demarcation and another is that the corresponding unilateral limitation of the derivative function at both side of the point of demarcation exist.
