How difficult are the final math questions in Beijing College Entrance Examination as follows:

The grand finale of mathematics class is the most comprehensive question type covering the widest range of knowledge in middle school mathematics. Based on the specific situation of the senior high school entrance examination in recent years, the finale questions mostly appear in the form of function formulas and geometric figures.

There are many knowledge points and hidden standards in the final exam, which requires students to have strong ability to understand, analyze and solve problems, have strong ability to control mathematical thinking methods and mathematical principles, and have strong innovation spirit and independent innovation ability. Naturally, they also need to have a strong personal psychological quality.

When solving big problems in mathematics class, we should keep in mind the mathematical ideas, turn big topics into small problems, and never forget the hidden standard. From static to multi-graphs, the classification discussion should be strict, the equation function should be a special tool, and the logical reasoning should be actuarial, so as to improve the quality of independent innovation.

The final question of senior high school entrance examination is a kind of question designed to examine students' ability to use basic knowledge flexibly, and it has the function of selecting and dialing. It is characterized by many knowledge points, wide coverage, hidden standards, complex relationships, difficult conception and flexible play. To solve the grand finale of mathematics class, we should not only have a solid basic theory, but also have skilled professional skills and master common problem-solving countermeasures.

When explaining the finale, we generally use the following mathematical thinking and methods to analyze the finale of the national senior high school entrance examination in recent years, most of which are related to plane coordinates. Its characteristic is that according to the corresponding relationship between the creation point and the number, that is, the coordinate, on the one hand, it can use analytic geometry to study the characteristics of graphics, on the other hand, it can rely on geometric intuition to obtain some explanations of analytic geometry problems.
