What should I pay attention to in the study of mathematics and physics in the second year of high sc

The formula theorem is the most important, and the exercises keep up with the angry cow.

Let's start with math, which is a headache for many science and liberal arts students. I'm not sure how to learn it, but lately I've been enjoying it. That's how I learned.

The insights and example problems of important mathematics textbooks, we must grasp this point, we must pay attention to the textbook, that is, you have just finished a section, if you have no ideas when doing exercises, you must recall what the textbook says, and you must achieve a clever combination of textbooks and exercises.

It is recommended that students in the first and second years of high school take several steps.

To preview before class, many books say so, but many students disdain, but I want to tell you, if you can implement the preview, your math can be half better, you should have a correct attitude when previewing, not to read the book once and finish, but to think carefully, to see how the content of the explanation and the example problems are connected. Then do the exercises in the book after you understand it, don't underestimate the exercises in the book, and many of the college entrance examination questions in the next few years are changed according to the exercises in the book, and this must be done well. Be sure to make a number and compare the answers.

Secondly, you should listen carefully in class, see how the teacher deduces mathematics, see if the teacher's statement is the same as when you previewed, it is best to write down the teacher's example problems, which are absolutely classic and can be used as objects to study.

Finally, it is necessary to complete the homework assigned by the teacher carefully, experience the content of the class, and ask the teacher in time if you don't know it. Also, it's best not to buy extracurricular workbooks, because according to my experience in the third year of high school, what I bought is a waste, don't buy it! If you feel like there's nothing to do, then learn English and Chinese!

If you learn these two subjects well, you don't need to review them in the third year of high school.

But everyone should remember that mathematics must implement all the problems, not procrastinate. It is also necessary to communicate with the teacher in a timely manner.

Physics is actually a few formulas and then use them in the problem, I can't say how to learn at all, because some people have asked me, I said for a long time they don't understand, but I finally said talk to your teacher, and in the end their grades really improved. What I want to say is that you should communicate your experience with the teacher in a timely manner, **No, the teacher will tell you how to learn.

The teacher's example problems in class are the most important, and a good physics teacher is to see if there will be classic examples in class. Therefore, as long as you pay attention to the explanation of the exercises in class and after class, it is OK. But it's important to do the exercises well!

In short, these two subjects are the most important aspects of science, rote memorization is bound to not work, and learning to use it after understanding is the truth.

1. Grasp the concept.

Doing math without understanding concepts is equivalent to reading articles without knowing words, and the first step in learning math is to memorize concepts.

2. Grasp memory.

Some people may say, how to memorize so many concepts, methods, and places to pay attention to? A good way to do this is to memorize it with the help of a slip of the tongue.

3. Grasp the system.

After each chapter, draw a knowledge structure diagram in time, pay attention to it, be sure to draw it from memory, correct mistakes again, and never copy the knowledge structure diagram on the book or tutorial book.

4. Catch the wrong questions.

In the second year of high school, physics focuses on electromagnetism and nuclear physics, and mechanics only has the conservation of momentum. Mechanics becomes more complex when momentum is added. Neither electricity nor nuclear physics and mechanics are related in the choice to fill in the blanks.

But the last piece of physics is definitely the electromagnetic composite field, which means that it uses all the aspects of electricity, magnetic fields, and mechanics.

Dear, physics is hard here.

Therefore, take advantage of the summer vacation to lay a solid foundation for the mechanics of the first year of high school, especially the circular motion part and the conservation of mechanical energy part, and the most important thing is to grasp the test point of the question.

Math: I'll give you another one in the evening

Mathematics in the second year of high school is very important, accounting for most of the math questions in the college entrance examination, and the calculations are very complex, especially ellipse and hyperbola, so you should practice your computing skills moreLearning math is like climbing a ladder, one step at a time to ,..

Do more questions and listen carefully! I'm a science student in my third year of high school
