Two important limits are the basic concepts in Calculus,and they are widely used in mathematical analy-sis and practical applications.Firstly,the significance of the first important limit is discussed,and the proof method of the first important limit is given by using the squeeze theorem.Secondly,the value of the second important limit is discussed,the proof method of the second important limit is given by using the monotone bounded sequence bound limit and the squeeze theorem,the main variants are discussed and proved,and the common characteristics of the main variants are discuss.Finally,the application of the two important limits in three aspects is explored.
