The effect of preview varies from person to person, and not everyone is suitable for learning mathematics through preview. If there are obvious situations in class, especially the basic knowledge, you must take a good look at the concepts the teacher is going to talk about in advance. If the teacher asks everyone to do the problems in class, you can't keep up, haha, this is normal.
How to preview? Don't ask too many questions, it's self-abuse to do it without knowing it very well. I suggest you focus on the concept and prototype, mark it with a marker, read it several times and write down what you don't understand.
The purpose of preview is to make the lecture more targeted, but don't make self-study like a dead end, you must know everything.

High school mathematics must pay attention to lectures! ! ! ! ! !
Unless your math teacher is already ruthless, you must strive to achieve the highest classroom efficiency.
Don't mess up your notes. Using some markers with different colors may make you feel better about taking notes, so that you can remember them more neatly. Notes mark your learning status. Notes may not look good, but they must be neat.
Pay attention to the teacher's thinking of solving problems, don't just stay in the realm of doing this problem, but grasp the thinking process revealed in the teacher's words, see what he thinks, see what prototype he thinks when he sees this figure, see what deformation he thinks when he sees that equation, and sum up the rules, which will be a sharp weapon for the exam.
In addition, there are generally different solutions to classic examples. Discuss it with teachers and classmates, or bite your head and think for yourself. If you have time, think about other solutions, which will broaden your mind.
It's best to cultivate some interest in mathematics, because no one can learn it well when driving ducks to the shelves.
My love for mathematics lies in breaking through one difficulty after another. Guan Yunchang broke through five levels and cut six generals, which is very heroic and can be used for reference ~

Sort out all the formulas first, especially the pile of trigonometric functions. I know them by heart, and I can deduce them and push them. Any problem is based on formulas, and you can't play without formulas, so you must memorize formulas, theorems and definitions.
Then make a list. Every formula has the most basic test method. You can ask the teacher. Each formula is accompanied by an example, so that you can master the formula from understanding to application.
Then do some simulation questions to see where your weakest point is, and don't worry about the location of those famous questions. See where the basic problems appear, accurate to the modules of knowledge, such as elliptic problems in functions, and then concentrate on practicing such examples.
Then I began to do some comprehensive exercises. Don't challenge difficult questions, just do basic questions. Next to each question, the test center of this question is marked. The wrong questions should also be marked with the reasons for the wrong questions and how not to repeat them (carelessness is not the reason for the wrong questions, but the underlying reasons are usually unfamiliarity, state problems and poor time arrangement. ), do a good job of accumulating wrong questions, and it is best to have a notebook.
Then proofread your answer format questions against the standard answers.
In the whole learning process, pay attention to summarize the hidden parts of the topic, such as the definition domain, such as the existence of k, such as quadratic function and quadratic function. These are easy for you to get points for a long time.
