Neste Interval Theorem and its application
Abstract:This paper introduces the description of real number continuity theorem -- interval sheath theorem,Introduced the interval defined, nested interval theorem, it focuses on the application of nested interval theorem proving theorems in real number completeness, Lagrange mean value theorem, the existence theorem of root and the application in the limit.To further explore the nested interval theorem and the life relation.This application can help readers to understand and extension theorem of nested interval in real life.
Key words:The closed interval theorem;Completeness of real number;limit;Lagrange mean value theorem.
