mathematics
Learning mathematics should be grasped as a whole. Generally speaking, mathematics can be divided into eight parts: function, sequence, solid geometry, analytic geometry, permutation and combination, inequality, plane vector, binomial theorem and statistics. Among them, function and geometry are especially difficult to learn, and they are also the key knowledge content. Understanding their respective characteristics and their relationship is the most basic content. To do this, we must first know some basic concepts, theorems and formulas in the textbook like the palm of our hand before we can use them calmly and freely. However, this knowledge is often the most easily overlooked-everyone is busy doing exercises one after another and buying thick exercise books one after another. How can they have time to read textbooks?
Some students may think that mathematics is not politics or history, and most of the exercises in the book are extremely simple. Why should we read textbooks? As we all know, textbooks are also very important for mathematics. There are 20% basic questions in the college entrance examination mathematics. As long as you spend a little time reading the textbook well, you can easily get these questions. On the other hand, if you are confused about some basic concepts and theorems, not only will you lose points in the basic questions, but you will also fail to do the difficult problems well. After all, these are the foundations. Mathematics is very logical and analytical, which can be said to be a purely rational science. You need to think clearly. It is unlikely that you can do the problem but don't know how to do it right, so basic knowledge is very important.
Secondly, quite a lot of practice is naturally essential. After understanding the basic concepts, we must do a lot of exercises, so as to consolidate the knowledge we have learned and deepen our understanding of the concepts. The so-called practice makes perfect, and mathematics can best reflect the philosophy of this sentence. Mathematical thinking, problem-solving skills, only in the exploration of the problem, will be impressed and handy. Of course, this is not advocating crowd tactics, but just a moderate amount. If you do too much practice, you will get bored easily. The most important thing is to choose a topic, which must be good and accurate. The teacher's suggestion in this respect is worth considering, and it is best to buy the reference materials recommended by the teacher. At the same time, do the questions according to your actual situation. Generally speaking, do the basic questions first, lay a good foundation, and then gradually deepen the difficulty and do some improvement questions. Every knowledge point must be consolidated through a certain number of difficult problems, so that it can be firmly mastered. After each problem is finished, you should look back (especially the difficult problem) and think about what you have gained from doing this problem, so that you won't do many problems without any effect.
Operation is also a very important link, as important as method. It is of course very important to cultivate a divergent thinking and seek various solutions to problems. However, some students have strong thinking ability and can think from various angles, but their computing ability is not strong, so they generally don't train. It's a pity that they often find the right method in the exam but calculate the wrong answer. Indeed, the tedious operation is daunting, but you will find many new problems in the operation process, and your operation ability will be gradually improved in training. Therefore, learning mathematical methods should pay equal attention to calculation. On the one hand, we should pay attention to the training of problem-solving methods and think about problems from multiple angles and aspects; At the same time, we should also pay attention to the exercise of calculation ability, pay attention to the accuracy of calculation, and don't be biased towards one side.
Summarize the test paper. Classify the special review papers and comprehensive review papers, carefully summarize each paper, pick out the topics with the highest gold content, and summarize all the related topics encountered. In this way, I can know all kinds of questions like the back of my hand and accurately grasp the questioner's angle. Through careful induction and summary of hundreds of test papers, many students' mathematics has been greatly improved. What needs to be emphasized is that in the process of summarizing the examination paper, we must go deep, never take the form, only in-depth can we gain something. Don't care about time during the in-depth process. Sometimes when summing up a big topic, related problems will be summed up together. This work is actually quite complicated, and it is by no means the same as understanding a topic. The benefits of doing this work are enormous. Therefore, it is very worthwhile to do it in one night. Don't be impatient when you see others doing problems one after another.
Usually study should pay attention to the following points:
1, step by step. Mathematics is an interlocking subject, and any link will affect the whole learning process. Therefore, don't be greedy when studying. You should pass the exam chapter by chapter, and don't leave questions that you don't understand or understand deeply easily.
Step 2 emphasize understanding
