In this paper, we present three innovative examples in advanced mathematics, i.e., the first-order derivative criterion of extremum of function of several variables, Rolle's mean value theorem in several-variable case, and the generalization of Rolle's mean value theorem. They are very close to the classic contents of advanced mathematics. Meanwhile, they are innova-tions based on those classic contents. By analyzing the thinking process of the three theorems, we reveal the ideology and methodology of mathematical innovation and discuss their educa-tional value.
