1, the overall knowledge setting of the new textbook has changed to the national examination outline. After using the new textbook, judging from the difficulty of the unified examination in each district and the repeated examination questions in the whole city, the difficulty of the mathematics paper in the college entrance examination in 2023 has increased, and the probability of approaching the national paper is greater.
2. The required inverse function has won a star rating in the new textbook and is no longer used as an inspection point. Some ordinary high schools no longer teach the content of inverse function.
3. Two old textbooks are required to teach trigonometric functions and series. The new textbooks are trigonometric functions, complex numbers and vectors. The trigonometric function has not changed. The product formula, differences and differences of products are increased.
(it was not mentioned in the textbook originally, because it was used in the exam, so it didn't have much impact. In many places, in the new textbooks, the multiple triangular representations and the principal values of radial angles for the selection of bird evening markers have become more, which means that the multiple triangular representations can be directly used in big questions. In the chapter of plane vector, the solution of triangle barycenter coordinates is clarified, that is, the barycenter formula can be used directly.
4. The compulsory three old textbooks were originally determinant and analytic geometry of Grade Two. In addition to determinant and matrix, the new textbook has been changed to solid geometry and probability statistics, and analytic geometry has been put in the first choice. Because the content of analytic geometry is limited, it means that students' ability to solve problems by pure geometry method has been improved in the solid geometry plate.
5. Elective compulsory courses include analytic geometry (rectangular coordinate system, cone), space vector and sequence. Part of the sequence cancels the limit part in the old textbook and is close to the outline of the national volume. Analytic geometry and space vectors are not much different from the old textbooks. Analytic geometry mainly adds knowledge about the second definition, which is unified with the national mathematics textbook.
The content of choosing one is the key and difficult point of many years' investigation of Shanghai volume, and the big topic of the final exam paper is often to investigate analytic geometry and sequence. Therefore, students should focus on these contents, strive to understand the definitions and properties of straight lines, ellipses, hyperbolas and parabolas, and learn the problem-solving methods of space vectors well, so as to get more scores in the exam.
6, optional compulsory two limited to choose two to add a chapter on derivative content, which has nothing to do with the old textbook. In the mathematics of the national volume, the questions in the derivative part are often combined to investigate derivative, monotonicity, combination of numbers and shapes, etc. , but it is not clear how to investigate the derivative knowledge points in the Shanghai volume.
