1. Triangle function or number column

The column is an important part of high school mathematics and the basis for learning high mathematics. The examination of the college entrance examination for this chapter is relatively comprehensive, and the differences in the differences will not be missed every year. Test questions about the number columns are often comprehensive questions. They often combine the number of knowledge and index functions, index functions, and unlimited knowledge of numbers. The test questions often make the equal number columns and equivalent schedules, and the limit and mathematical induction method are integrated together. Exploration is the hotspot of the college entrance examination, which often appears in the number of answers. In this chapter, we also contain rich mathematical ideas. In subjective questions, we focus on examining the basic mathematics methods such as the function and equation, the transformation and return, and the classification discussion, as well as the mathematical methods such as the method of distribution methods, the change of the element, and the establishment of the coefficient method.

In recent years, the propositions of the college entrance examinations are mainly in the following three aspects; (1) the relevant knowledge of the number column itself, including the concepts, nature, general formulas and formulas of equivalent and equivalent ratios. (2) The combination of numbers and other knowledge, including a series of columns and functions, equations, unqualifications, triangles, and geometry. (3) The application of the number column is mainly based on the growth rate. There are three levels of difficulty in test questions. Most of the questions are based on basic questions. Most of the answering questions are mainly based on basic questions and mid -range questions. Essence

Second, three -dimensional incidents

There are generally 4 three -dimensional geometry questions in the college entrance examination (3 selection, filling in the empty questions, and 1 answer questions). The total score is about 27 points, and the knowledge points of the examination are less than 20. Choose the calculation of the blank questions to assess the number of calculations, and the answer questions focus on the logical reasoning issues in the few. Of course, both should be based on the proper space. With the further implementation of the new curriculum reform, the three -dimensional geometric test questions are thinking a little more and less calculated. Judging from the changes in the test questions over the years, the analysis of the line position relationship with simple geometric body as the carrier, the perspective of angle and distance is a common new topic.

3. Statistics and probability

1. Master the principle of classification counting and step -by -step counting, and use them to analyze and solve some simple application problems.

2. Understand the significance of arrangement, master the formula of the number of arrangements, and use it to solve some simple application problems.

3. Understand the significance of the combination, master the nature of the combination calculation formula and combination, and use them to solve some simple application problems.

4. Master the nature of the dual -e -terms theorem and two -pushes, and can use them to calculate and prove some simple issues.

5. Understand the significance of regularity and probability of random events.

6. Understand the significance of the probability of possibilities such as possible events, the probability of calculating some possibilities with the basic formulas of the arrangement combination will be used.

7. Understand the significance of mutual exclusion events and independent events, the probability of the mutex event plus the formula and the probability multiplication formula of each other to calculate the probability of some events.

8. Accounting calculation incidents in the N independent repeated test happened to occur.

Fourth, analysis of geometry (cone curve)

Analysis of the analysis of the college entrance examination:

1. Many college entrance examination issues are based on the points, straight lines, curves (such as circular, ellipse, parabolic, and bilateral).

2. The interpretation rules are the interpretation rules of the algebra, or the rules of the equation and interpretation equations.

With the above two points of understanding, we can not hesitate to conclude that it is nothing more than two tasks to solve the analysis of the analysis of the college entrance examination:

1. Geometric issue algebraicization.

2. Use the rules of the generation to deal with the problem of algebraicization.

Fifth, function and guide number

Guidance is a preliminary knowledge of calculus, a powerful tool for researching functions and solving practical problems. In the high school stage, the learning of the guide is mainly the following aspects:

1. Conventional problems of guide numbers:

(1) portraying functions (precise and subtle more precise than primary methods);

(2) Cut the line in the geometry (the guide method can be used to study the cut line of the plane curve);

(3) Application issues (the initial methods are often technical requirements, and the method of guidance appears to be simple). The guidance problem of sub -e -spots is difficult.

2. About functional features, the most valuable problems, so it is necessary to discuss it. The most valuable method is faster than the primary method.

3. The problem of the mix of guidance and analytical geometry or function image is an important type, and it is also a direction for examining comprehensive capabilities in the college entrance examination, which should be noticed.
