If we start from scratch, we must first talk about the consolidation of junior high school mathematics. You can choose some reference books for the general review of junior high school mathematics to help you review.
Then I began to review high school mathematics.
Now I am a senior three student, and I should have entered the general review stage. Then you must keep up with the pace of the teacher. We should also consolidate after class. Generally, senior three will review three rounds. The first round is to consolidate the foundation. If you haven't listened much before, the first round is very important, because teachers usually review the first round in detail. If you don't understand, you can ask your classmates or teachers.
The above is my personal opinion. Here are the answers to the questions ~
First, the most important thing about trigonometric functions is to remember trigonometric formulas. When doing the problem, we should pay attention to finding the similarities between the problem and the formula, and then substitute it into the formula. Do a few more questions and look at the solution ideas of the answers against the answers. Seeing too much makes it easier for them to find a breakthrough point.
Second, in fact, I don't have any new knowledge in the third year of high school ... I'm usually a sauce purple → my exercise book is a summary of the main content of this lesson at the beginning of each class. I always fill in the blanks with answers, and then compare the induction with this textbook. Then listen carefully in class and do exercises after class to consolidate your knowledge. I think math is to do more problems. If I do more, I will feel better.
Third, the experience is above = = After the foundation is solid, the utilitarian point is to specialize in the preparation of the college entrance examination ... My method is to review which piece of knowledge and do topics related to that piece of knowledge in each compilation. Just go through the main idea in a relatively simple little problem. After browsing the ten questions, I almost know the general questions of the college entrance examination and their solutions. The big problem is to really do it, but it doesn't need to be done a lot, just for a day or two. In particular, it's like knowing a few things that must be difficult to test. Usually, the thinking of solving problems is fixed, and the difficulty lies in calculation. Therefore, if you keep practicing your calculation ability, your math ability will be improved accordingly.
Generally, you are afraid of math because it is not good. When your math is improved and it is easy to do problems, you will find it interesting and take the initiative to learn. So it is very painful to be afraid that it will be forced to get along with it day and night in the early stage. I am Jiang Zi ☆ _ ☆ Besides, be careful not to neglect other subjects because of short legs. It is also important to arrange time reasonably.
