Upper and lower limit of sequence and it’s application
Abstract:The limit is a very important basic concept of mathematical analysis, it is also a important content in mathematics study, limit thought plays a very important role in mathematics. The concept of upper and lower limit of sequence is an extension of the limit of sequence, playing a important role in the concept of the limit. This paper firstly introduces the definition of upper and lower limit of sequence and it’s related properties.Since the sequence is a kind of special functions, then it gives the definition of upper and lower limit of function and it’s related properties. Finally, give the application of the upper and lower limit of sequence and function.
Key words:sequence;function;upper limit;lower limit
