Research on Solving Skills of the Second Important Limit Questions in Advanced Mathematics

摘要

The first section of Advanced Mathematics are Functions and Limits and the limits include two important limit formulas of the first important limit and the second important limit which are still valid. In actual process of solving, questions generally are the deformation of the important limit, especially the second important limit. In order to solve them by the formulas, the deformation should be changed to the form of the formulas before calculation, which is complex and easy to make a mistake. Therefore, a simple algorithm is given in this paper by seeking out the relationship between the questions and simplifying the process of transformation.
