Course-based problem sets are arranged in the order of mathematical analysis courses-of course, this is not necessarily a logical order-with the following characteristics: the previous knowledge must be the logical basis of the later knowledge; There may be examples, thinking questions, review questions and other auxiliary learning questions; Generally, there is a summary of knowledge points before the chapter (such as Zou Ying's mathematical analysis exercise solution).
Comprehensive exercise set refers to an exercise book that integrates and combs all the contents of mathematical analysis and arranges them according to logic or knowledge structure (such as Pei's Typical Problems and Methods in Mathematical Analysis).
Book-based problem sets are books that focus on the height of mathematics, gather valuable problems that have not been produced until recently in analytical disciplines, and present their core significance through careful processing. Itself is a work of mathematical analysis and research (such as halmos's Hilbert Space Problem Set).
