Primary analysis of counter-example
in mean value theorem of differentials
Abstract:Constructing the counter-examples by changing the conditions in mean value theorem of differentials,the present paper confirms the conditions in mean value theorem of differentials is abundant.At the same time,the relation of theorems is pointed out by analysis of the conditions.
Keywords: Counter-example; Fermat’s theorem; Rolle’s theorem; Lagrange’s mean value theorem; Cauchy’s mean value theorem.
