摘要
本文用归结原则将函数极限问题转化为数列极限问题去讨论,证明了函数极限性质与极限存在的判定定理,进而更清晰的刻画了函数极限与数列极根之间的关系。
With the principle of summing up, the problem about the limit of functions converted into the limit of sequences is discussed in the paper, the properties and the existence of the limit of functions are proved, so that the relation between the limit of sequences and the limit of functions is described more clearly.
