There are four compulsory knowledge points in mathematics in the first year of high school, and four

The first stage of high school is the stage of laying the foundation, and it is the key stage of winning the college entrance examination in the future. The following is cheering for you!

1.There are four compulsory knowledge points in mathematics in the first year of high school

The common ratio is q of the proportional series, from which the equidistant terms are taken out to form a new series of numbers, this series is still the proportional series, and its common ratio is q (m is the difference between the number of terms of equal distance). For any m and n, there is: a=a·q in the proportional series, and in particular, when m=1, the general formula of the proportional series is obtained, which is more universal than the general formula of the proportional series.

In general, if t, k, p ,...，m，n，r，…are all natural numbers, and t+k, p,...，m+…=m+n+r+…(The natural numbers on both sides are equal), then when it is an equal proportional series, there is: . ...=。Yulu ....

If it is a proportional series with a common ratio of q, then the 、、、 is also a proportional series, and its common ratio is |q|}、

If it is a proportional series and the common ratio is q, then, a, a, a, ,...，a，…It is a proportional series with q as the common ratio.

If it is a proportional series, then for any n there is, there is a·a=a·q>0.

The series formed by the product of each corresponding term of the two proportional sequences is still the proportional series, and the common ratio is equal to the product of the common ratio of the two series.

When Q>1 and A>0 or 00 and 01, the proportional column is a decreasing series; When q=1, the proportional column is a constant column; When Q

1. Pay attention to listening and lectures in class, and review in time after class

Accept a new kind of mathematics knowledge, mainly in the classroom, so you should pay attention to the efficiency of mathematics learning in the classroom, find a suitable method for learning mathematics, and follow the teacher's ideas and think positively in class. When doing homework, first recall the content explained by the teacher in class, but also firmly grasp the formula and reasoning process, and try not to turn the book. Try to think for yourself and don't rush to look at the answers.

It is also necessary to summarize and review frequently, combine knowledge points, and turn them into your own knowledge system.

2. Do more questions and develop good problem-solving habits

If you want to learn mathematics well, you must avoid doing a lot of problems, and master various types of questions proficiently, so as to effectively improve your math score. At the beginning of the problem, first focus on the exercises in the book, answer the basics well, and then gradually increase the difficulty of mathematics, develop mathematical ideas, practice various types of problem-solving ideas, and record the types of questions that are prone to errors, and repeatedly link them. When doing questions, you should develop good problem-solving habits and concentrate your attention, so that you can enter the best state and form habits, so that you can use them freely during the exam.

Look at your notes first and then do your homework. Some high school students feel. What the teacher has said, I have already heard clearly.

But why is it so difficult to do the questions yourself? The reason for this is that the students' understanding of what the teacher is saying is not yet at the level required by the teacher.

Therefore, before doing homework every day, be sure to read the relevant content of the textbook and the class notes of the day. Whether or not you can persist in this way is often the biggest difference between good students and bad students. In particular, when the practice questions are not very matched, there is often no type of question that the teacher has just talked about in the homework, so it cannot be compared and digested.

If you don't pay attention to the implementation of this, it will cause great losses over time.

It is necessary to buy practice questions that suit your ability to do it again (but note that don't just seek speed, try to be as organized as possible, which helps to improve our thinking and logical ability,) and usually pay attention to accumulation, pay attention to induction, and then, the necessary formulas, axioms should be able to memorize, but also be able to use, if you can't use it, it's better not to memorize.

Therefore, doing more questions can improve our understanding and memory of formulas and axioms to a certain extent. Finally, we should take every exam seriously, because in the exam, we can see our own shortcomings, which is conducive to our improvement. Learning math well is a long process, and there may be no shortcuts, only hard work.

As long as you work hard, I believe you can improve your math score quickly.
