Some reference textbooks for mathematical analysis in universities are the second edition of East China Normal University, but we all use the third edition or even the fourth edition, which has no influence on the postgraduate entrance examination. You can use the third edition to review. Chen, the textbook required by my original school, I also used two books reviewed by Chen Jixiu of Fudan University. In fact, the knowledge points of each set of textbooks are similar, and the inspection will not be too bad.
So you can use the third edition completely, don't worry about the version.
Hope to adopt
