1. In fact, the teaching content of the first compulsory course is basically the same as that before the reform. In the first book, the trigonometric functions of compulsory one and compulsory four are combined with the trigonometric identity transformation and compulsory five inequalities in the original version of textbook A of People's Education Press, and the original self-selected propositions and common logical terms are also combined into the compulsory content of the first book.
2. The contents of Compulsory Volume 2 also merge the vector part of Compulsory Volume 4, the preliminary solid geometry of Compulsory Volume 2 and the statistics and probability part of Compulsory Volume 3 in the original version A, and at the same time add the plural part that originally appeared in the elective course. As can be seen from the contents of the new textbook, the original three-view and program block diagram have all been deleted. Now I just want to introduce the concept of direct vision to you.
3. It can be clearly felt that the author of the new textbook combines the related contents of coordinate system and analytic geometry, and the difficulty and emphasis of this book is calculation, which is more difficult than the required content.
4. The second volume has relatively few compulsory contents, only two chapters, and the corresponding contents are related knowledge of sequence and derivative. This reform is still very meaningful. The series of the original compulsory five is directly classified into the elective module and merged with the derivative into one book. The proof of mathematical induction in the original elective course is also merged into the sequence module.
5. The main content of the last elective book is counting principle and probability, and a small part is linear regression equation. In fact, the general requirement is to let students learn how to process data. Mathematical modeling, which has been publicized before, also appears in the third elective compulsory book, which shows the reformed teaching content and pays more attention to cultivating students' mathematical application ability.
