Limit is important mathematical thought thought, it comes from the real world. In ancient China from the bud of development to limit thought limit theory establishment, how many mathematicians with the hard work, rigorous doing scholarly research, hard process. It was set up the development of social economy needs, but also an important turning point in the history of mathematics and one of the basic theory of modern mathematics.
Newton, les bunni this and a number of mathematicians, introduced variable, function, limits, concepts, such as the calculus, make long troubled people's problems can be solved. They not only make higher mathematics elementary mathematics developed, also used to other disciplines, drive the other disciplines progress, become the scientific method to deal with problems. To summarize and discuss the concept of limit thought and nature, to use and master thought the limit, the cultivation of the students' innovation consciousness and abstract thinking plays an important role.
This paper also introduces the higher mathematics sequence limit and the concept of function limit, key points out that the nature and it is also given. The limits of mathematics thought the settlement of some of the discipline's practical problems, and to make a preliminary discussion and study.
