How to learn high school math well

That's just why you don't think it's difficult.

In fact, there is no difference between difficult and not difficult, many high school students have this feeling, it is a math problem, which can often be done usually, but cannot be done during the exam. That's because the high school math exam has been in a state of large amount of questions and little time, and it is normal to not finish it, let alone check it. So in this case, it is very important to ensure the correct rate, otherwise it is not possible to do what you can't do, and you are doing it wrong, how can you do well in the test.

I once took a paper with a total score of 170, the amount of questions was terrifying, and I felt miserable when I took the exam, I didn't get 130, but the highest score in our class was 165, speechless.

Mathematics requires the foundation, small concepts must be clear, the first few questions of the general test paper are concept questions, very simple, but if you forget, it's over, college entrance examination mathematics multiple-choice questions 12 questions, fill in the blank questions 4 questions, the time is best not to exceed 40 minutes, so when doing it, you must be good at finding rules and finding easy methods, otherwise the next 6 big questions will be no play.

The big topic will test a trigonometric function, and it will not be difficult to memorize the formula.

For a question of solid geometry, it is recommended that you usually use the traditional method to do it, train your thinking, and use the vector method to do it in the exam, because the vector method is very dead and can save time.

There will also be a question about the combination of derivatives and functions, and classification discussion is very important.

A probability question, it may be a little difficult to learn probability at first, it is good to do more questions, and I personally think that probability questions are relatively simple in the college entrance examination.

The general idea of analytic geometry is very simple, the calculation is very troublesome, and it is very closely combined with the Veda formula.

The combination of a series of numbers and inequalities is very difficult, and it is very demanding for thinking.

All in all, the foundation should be solid, the computing power is very important, and the calculator should be used sparingly, although it is difficult for us to do it. If you don't do it during the exam, you can put it away, don't waste too much time, it's best to fill in the blanks and check the choices, the two add up to 76 points.

ps: We're in the third year of high school this year, and we're about to take the exam, nervous

The study of mathematics].

The examination of mathematics is mainly based on the basics, and the difficult problems are only synthesized on the basis of simple problems. Therefore, the content in the textbook is very important, if the knowledge in the textbook cannot be mastered, there is no capital to touch the class.

For the content in the textbook, it is best to preview it before class, otherwise there is a knowledge point in class that does not keep up with the teacher's steps, and the following will not know why, so a vicious circle, you will begin to get bored with mathematics, and interest in learning is very important. After all, during class, it is the teacher who is calculating and explaining the problems, and the students are listening, which is a more mechanical and passive process of receiving knowledge. You may think that you have understood it in class, but in fact your understanding of the problem solving method has not reached a relatively deep level, and it is very easy to ignore some of the difficulties that must be encountered in the real problem solving process.

A good brain is better than a bad pen". For the solution of mathematical, physical and chemical problems, it is not enough to rely on the general idea in the head, but only after careful pen calculation can we find the difficulties and master the solution method, and finally get the correct calculation results.

Secondly, we should be good at summarizing and classifying, looking for commonalities and connections between different question types and different knowledge points, and systematizing the knowledge we have learned. To give a specific example: in the function part of higher algebras, we learned several different types of functions, such as exponential functions, logarithmic functions, power functions, trigonometric functions, etc.

But if you compare them and summarize them, you will find that whatever kind of function, all we need to grasp is its expression, image shape, parity, increase and decrease, and symmetry. Then you can make the above contents of these functions in a big **, and compare them to understand and remember. When solving problems, pay attention to the combination of function expressions and graphs, and you will definitely get much better results.

Finally, it is necessary to strengthen after-class practice, in addition to homework, find a good reference book, and try to do as many practice questions as possible in the book (especially comprehensive questions and application questions). Practice makes perfect, so that you can consolidate the effect of classroom learning and make your problem solving faster and faster.
