The eighth edition has comprehensively revised and supplemented the contents of the seventh edition, added some new knowledge points and examples, and optimized and improved the original contents. Specifically, the eighth edition is slightly more difficult, paying more attention to the combination of theory and practice and cultivating students' mathematical modeling ability and application ability. The seventh edition pays more attention to the explanation and practice of basic knowledge, which is suitable for those students who need to lay a solid foundation.
