The math difficulty of senior one is 1, and the test site is related to combination function and set.
The core of compulsory mathematics is actually a function, and the assessment around the function is definitely a set. It is not difficult to collect knowledge points alone, and everyone can learn well. However, it is difficult for freshmen to combine assessment with function. I suggest you practice more at the relevant test sites. Practice makes perfect.
2. Functional scope
Function evaluation domain is a difficult point for senior high school students. Everyone must attach great importance to the test sites related to the functional scope. If you learn the range of functions, you need to work harder. In the following courses, we will also explain the relevant content in detail with specific exercises.
3. Expressions of abstract functions
The expression of abstract function is also a compulsory point, even a difficult point. In many cases, the expression of the function will be evaluated in the form of function value, and combined with the comprehensive test points such as symmetry and parity periodicity of the function. Many students will be stumped here. I suggest you start with the basic test sites and practice comprehensive exercises after winning each test site.
How to learn mathematics in senior one 1? Read your notes first, then do your homework. Some senior one students feel that they have heard what the teacher said clearly. But why is it so difficult to do the problem by yourself? The reason is that students' understanding of what the teacher said did not reach the level required by the teacher. Therefore, before you do your homework every day, you must take a look at the relevant contents of the textbook and the class notes of that day. Whether you can stick to this point is often the biggest difference between good students and poor students. Especially when the exercises are not matched, there are often no questions in the homework that the teacher just talked about, so it is impossible to compare and digest them. If we don't pay attention to this realization, it will cause great losses over time.
2. Strengthen reflection after doing the questions. Students must make it clear that the topic they are doing now is definitely not the topic of the exam. But to use ideas and methods to solve the problems we are doing now. So we should reflect on every question we have done and sum up our gains. To sum up: what is the content of this question and what method is used. Turn knowledge into pieces and questions into strings. Over time, build a scientific network content and method system. As the saying goes, "money is hard to buy." We think it is very valuable to finish your homework and look back carefully. Review is a very important link in the learning process. See if you did it right; What other solutions are there? Where is the topic in the knowledge system? What is the essence of the solution; Whether what is known and what is sought in the topic can be interchanged, and whether it can be added or deleted appropriately. With the above five reviews, students' problem-solving ability can increase day by day. Although the time invested is very small, the effect is great. Can be called twice the result with half the effort. In professional language, it is to improve students' mathematical ability, so that students' ability to use knowledge and solve problems can be migrated from a distance.
3. Pay attention to correcting mistakes and not repeating them. We must pay attention to correcting mistakes so as not to make mistakes again. The method adopted in junior high school mathematics teaching is to tell students all possible mistakes. As long as one person makes a mistake, it is necessary to bring it up for all students to learn from. This is called "everyone takes medicine when he is sick." There is not so much time in high school math class, except for a few typical mistakes, we can't take care of other mistakes. Only "who is sick, who takes medicine". If a student is "sick" and forgets to take medicine, then no one will remind him of something again and again. If mistakes can be corrected in time, they may become wealth and become preventive measures to prevent such mistakes from being made again. But if we can't correct the mistake in time, it will form hidden dangers and "mines", and it will get into trouble sooner or later. Some students think that they can't get up on the exam results because they are too careless in doing the questions. Besides, I am careless. Actually, it's not. For example. Like learning to drive. Under the right foot, step to the left, that is, step on the brake. Go right and step on the gas. Its mechanical principle, design reasons and operating procedures can be clearly stated. If the new driver really knows this, can he be allowed to drive to the streets? I'm afraid he knows he lacks practice. Just because you can finish the task correctly once or twice doesn't mean you will never make mistakes. Lack of practice is often the real reason why students make mistakes. We must see that if our basic background is full of mines and hidden dangers are endless, it will be difficult to learn math well in the future.
