In recent years, the finale of the senior high school entrance examination is rich in content. By studying the formation and proposition trend of these problems, we will find that the solution of the finale is clearer and the fear disappears. The following comments on the characteristics of its proposition according to the knowledge points it contains, and analyzes its problem-solving ideas.

Anyone who likes learning mathematics will know.

When all kinds of knowledge points are understood and familiar, they will be connected into a knowledge network by doing problems.

Especially the combination of numbers and shapes.

Compare the function questions of the senior high school entrance examination in recent years before the exam.

You will find that they are similar.

For example, the synthesis and application of all functions.

1。 Let you write the relationship between y and X. Solve several common problems by comparing relationships.

3. Find the maximum value of XX (I must ask you to write the functional relationship format: x=-, Y has the maximum value).

If there is a related problem of finding the focus of two functions

Must be simultaneous equations (this basic problem should not be afraid)

If the moving point problem of geometry is a function conjecture.

Find two related variables through knowledge such as similarity.

List their analytical formulas (pay attention to the increase and decrease of functions when discussing)

. . . . . In fact, the knowledge of 4 5 common situations has changed.

You'd better think for yourself and ask the teacher to supplement it for you.

Next, find some questions yourself and try to use the ones just sorted out.

-easy to do, don't be afraid of the senior high school entrance examination.

I studied for two months in the senior high school entrance examination.

This method is also very useful.

The last sentence: The second best thing is because the questions in the senior high school entrance examination will not exceed 20 points ()

The function finale is usually 3 questions, 12- 15 minutes.

The first question and the second question are basically given for nothing.

Principle: the first question must be done (the first question is given points)

The second question (do what you can)

The third question is whether to do it (except those who are good at math)

Therefore, in the case that time is not particularly sufficient, it is recommended to keep the basic questions.

Let the questions in the meeting be 100%, right? -

Come on O(∩_∩)O
