Abstract: this paper begins with a brief analysis of Rolle's theorem in differential calculus and analysis on the basis of proof of Lagrange's mean value theorem, gives another very useful proof of Lagrange's mean value theorem, then leads to the core of this article, that is, application of differe

Summary: This text has analyzed the position in differential calculus of the value theorem in Luol shortly at first, then on the basis of thinking of identification of the value theorem while analyzing Lagrangianly, another very useful identification of value theorem while providing Lagrangianly, th
