Learn high school math problems, high school math problems

Maybe the teacher doesn't teach well, but don't explain the problem from the teacher.

In fact, you should have a boredom with math, which will make you even more uncomfortable. Interest is the best teacher.

Love math. Don't be afraid of a bad test, you should trust yourself.

Clause. First, you must carefully do a good job of pre-class preview, write down what you don't understand during the preview, and listen carefully when the teacher talks in class. This will allow you not to faint during class.

You will be serious in class, take good notes, write down the typical examples given by the teacher, and what you don't understand, and ask the teacher after class.

Clause. 2. Think more and do more questions. There must be a certain tactic of the sea of questions. Make good use of the answers from the information you have. Set what questions to do every day, do a lot well, and have a plan. You can now do some relatively simple typical questions before doing them.

For one or two relatively difficult questions, think carefully, write down everything you know, and then understand the answers, rather than simply answering them, and connect them with the knowledge points in the book to understand its solution methods and ideas.

Clause. 3. This is generally forgotten, but it is an important point. You must read your math book well, eat it thoroughly, and understand it. The prototype of all questions is a book, so a book is very important.

Clause. Fourth, now start to master various methods of problem solving. For example, the elimination method of multiple-choice questions, the special value method, as well as the exchange method, the drawing method, the counter-evidence method, etc.

Don't feel that the pace of the teacher's class is something you can't keep up with, but you don't do your best, or your potential is not being developed. Generally speaking, if you think of complaining about not being able to keep up with the rhythm, it means that the teacher's pace is fast. But in fact, a faster pace is beneficial, both for good grades and for average.

For those with good grades, speed up the progress, learn more, and enhance the desire for knowledge; For generally, keep up with your mind and not be easily distracted. Of course, if you get distracted, then at least you can listen to the next question, so you have to keep up with your thinking. If it's a canonical example, you can consider writing it down.

After class, I carefully integrated into my own thinking.

Of course, the sea of questions is also a good way, mathematics belongs to a type of writing that is easier and easier, of course, it is a question of the same difficulty. When you're comfortable writing at this level, then you can increase the difficulty. Increase slowly, don't be in a hurry, you can't eat hot tofu in a hurry.

Don't be bothered at first because you can't write the topic, as it will only consume time and patience. You can consider lowering the difficulty, the difficult questions are often a sublimation of the easy ones, so the easy questions are also the basis of the puzzles.

I'm a lazy kid, just like you. I'm too lazy to copy my homework in the morning, and occasionally write it myself. However, looking at the example questions for a long time, as well as following the teacher's ideas in class, it is basically not very difficult, and it can be polished with time.

But remember, you have to listen to the lessons, especially like math. After listening to the lecture, you will subconsciously react. If you ask questions for a long time and look at example questions, then you will have a reaction to seeing the questions - pick up the pen and start it.

It's past in my head.,I don't know what I just thought after writing.,You have to look at the process of writing to know what you just thought (this situation is also depressing.。 ）

I think my situation is very similar to you, I am in the science experimental class of Chang County, Hunan Province, just entered the summer vacation of the first year of high school, the teacher rushed to catch up with the progress and the content is more, I never took the small test in our class at that time, but now I am in my third year of high school, the monthly exam mathematics 135+, the method is to brush the questions first, what 5.3 difficult manual Wang Houxiong did a book for a year, and then threw away the sea of questions and began to ask questions, and finally remembered some traps, skills, this as long as you miss it once, you will basically not forget. There is also my own feelings, in fact, I think the teacher just answers the questions better, to understand the basic impossible, or do the questions first, a bunch of people outside said to jump out of the sea of questions, do not do the questions at all do not know what mathematics is, put 5.3 from the first page to do it, one by one solid to figure it out, mathematics improvement is only a matter of time.

You may put too much pressure on yourself, don't let yourself fall into mistakes, and you have to understand that high school is different from junior high school, no matter how good your grades were before, you have to learn to forget and start from scratch! As long as you calm down, you must know that your situation is very common, and it may be a little difficult at the beginning, but you must believe that persistence is victory, and at the same time, you must believe in yourself, you will definitely succeed, and you will be able to do what everyone can do! You can do more math problems in your daily life!

That can help you, and you must ask if you don't understand (whether you ask the teacher or classmates), to learn to draw inferences, my suggestion is that you can do something simple first, from shallow to deep! I want to build confidence in myself and not be affected by the success of others!

Good luck!

Hello I have had my own troubles with you. For mathematics, I think the most important thing is to grasp the overall situation and think holistically. First of all, you have to overcome psychologically:

I'm sure I'll be able to do math well! And for the most basic exercises, you must be careful and do it yourself, don't think it's too easy, because it's all about consolidating some very basic knowledge. Also, it is very important to summarize it yourself, you must!

No matter how bad your own summary is, it is also your own thing, and no matter how good others summarize, it is also someone else's. Summarize it yourself, and then improve Then, you will have a sense of accomplishment For summarization, the main thing is to summarize the method of the problem and the knowledge used. For example:

There will be a lot of questions about judging the monotonicity of functions, so you think, what are the methods for judging the monotonicity of functions? For example: the definition method.

The definition method also includes the comparison of difference and 0 and the comparison of quotient and 1. There are also some small tricks), derivation, etc. (however, for the first year of high school, definitions are generally used more, that is, some small tricks will be interspersed when using definitions.) These are all accumulated on a daily basis, and there are almost no shortcuts to learning, so work hard and move forward steadily!

Wishing you a good, big progress!!

Your high school entrance examination results are very good, indicating that your mathematics foundation is okay, the problem lies in your new knowledge, my suggestion is that mathematics as a main course, you must not spare time, read more textbooks, grasp the basic knowledge firmly, preview in advance, and match the knowledge points in the book with the teacher. Mathematics is a logical course, the result is derived from the conditions, it is rarely created out of thin air, and those complex problems are also composed of simple problems, if you do not master the basic knowledge well, it will be more difficult to solve the comprehensive problems in the future.

High school math is still not very difficult, learn the textbook well, and ask if you don't understand. Everyone understands this, so I won't talk about it. According to your situation, you have to do the following, you are enterprising, you must have the determination to sprint for the college entrance examination, and do more questions and more things.

I believe you understand that you have to take the college entrance examination, maybe you will be motivated) I hope you can learn mathematics well and sprint for the college entrance examination. Pure mobile phone writing, top down!

I was in the same situation in high school, I was always in the first and second places in math in junior high school, but I didn't do well in high school. I think there is still a little bit of a gap between psychological imagination and reality, but mathematics, listen carefully in class, look at more example problems and broaden the question type, and it is necessary to practice more practice questions, and it will be much better to do more problems, this is mainly to rely on your own practice, come on.

Middle school math is somewhat different from high school and more abstract. Therefore, some students will have an adaptation stage, don't be discouraged because of the poor learning effect for a period of time, sort out your emotions, calm down and think about it and adjust your learning methods, you will definitely pass this stage smoothly, come on!

Don't be too stressed! High school depreciation shows that your method is not suitable for you in high school! You have to do more math, but don't do one question type all the time and do different question types. After doing it, think about other ways to do it, and then draw inferences.

1.You must have a good grasp of concepts, formulas, which are the core of mathematics; 2.Master the corresponding concepts by doing 2 questions; 3.

The key to accumulating problem-solving methods is to have your own heart; 4.Under the guidance of the teacher, do the question type with strong classic knowledge points, and you must understand it when you do one.

Correct your mentality, attitude is everything. Teachers are only part of the story, the key is to change your thinking and adjust your learning methods.

I think that if you want to learn high school mathematics, you must understand every example problem taught by the teacher. And to do more problems, mathematics is a typical sea of questions tactics.

Do more questions, and the key is to go back, and do a good job of making mistakes.

Let z=x+yi

The modulo of z is 1 so: x 2 + y 2 = 1 (1).

z^2+2z+1/z=x^2-y^2+2xyi+2x+2yi+1/(x^2+y^2)(x-yi)=x^2-y^2+2xyi+x+yi+x-yi=x^2-y^2+3x+(2xy+y)i

The corresponding point is on the negative half axis of the real axis So: x 2-y 2+3x<0 (2) 2xy+y=0 (3).

Substituting (1) from (3): x=-1 2 or y=0 to (1) yields y = 3 2 or x = 1

Substituting (2) knows: x=-1 2 ; y = 3 2 with x=-1 ; y=0 can be solved but x=-1 ; y=0 is the solution of the real number.

z=-1/2+±√3/2 i z=-1

1)ab^2=

ab(ac+cb)+

AB 2+ angle c is a right angle, and the triangle is a right triangle.

2) From the inscription, we know two equations: into + sin

From the formula 1, we know that = bring in 2 to get 4-cos = into + sin to get 4-(1-sin )=into + sin to get in=sin -sin +3=(sin -1 2) +11 4-1, so the range of values obtained is 11 4 "into <53) method 1:

ABC and point M satisfy the vector MA+vector MB+vector MC=0 Point M is the center of gravity of the triangle ABC.

It is known by the nature of the center of gravityma|=2 3 of the length of the midline of the bc side, that is, the length of the midline of the bc side 3 2|ma|

again the vector ab + vector ac = m vector am

Vector ab + vector ac|= 2 times the length of the midline of the BC side.

Vector ab + vector ac|=3|ma|=3|Vector am|That is, vector ab + vector ac = 3 vector am

m=3 Method 2:

Solution: (The following line segments represent vectors).

ma＋mb＋mc＝0

am＋(ab－am)＋(ac－am)＝0∴ab＋ac＝3am

m＝3

The most important thing in mathematics is to form ideas, don't let the question adapt to you but you adapt to the problem, see a question to find the general direction, think of what the question asks, what knowledge points are involved, what it ultimately wants, and to get this you need to find something, from the result of asking you to push forward, that is, from the back to the front to the front, from the front to the back to write, often refined, open their own ideas! Give it a try.

Start with the concept, and then practice questions after class, first grasp a point, eat thoroughly, for example, if it is a problem with the formula, the first step, remember the formula, remember the method of the formula, you can repeatedly memorize it in your heart, write at the same time, know the meaning of each letter, and then do the after-class contact, that is, the most basic exercise, directly use the formula, to do a lot, know that you are particularly proficient, you must calculate carefully, and the calculation ability is the premise of your road. When you have mastered this foundation, you can do the exercises after class, followed by the test papers.

The same is true if it is applied in the case of definition theorems, axioms, etc.

Keep in mind that concepts, definitions, formulas, etc. are roots, other exercises, exercises. Test papers, etc. are branches and leaves.

I started in high school math in the 40s and 50s, and in the last month I improved to 117, which was not too high, but it was far better than my previous record.

Hope it helps.

Books - Chapters (What is each chapter about, and how much are you familiar with?) 1. How many points are there in each chapter, --- the main points, the difficulty, and the difficulty?

2. How much is the basic understanding?

3. What is the test point for the practical training --- to do a question? Draw inferences and strengthen the impression!! What if the verification does not have this condition? Can it be achieved?

4. Interest is the best teacher to cultivate your interest in mathematics and cheer yourself up!

5. Put down all your baggage and work hard to move forward!!

I teach high school math, and I let my classmates do two things well, foundation + persistence! The basis is to be able to say all the knowledge points by looking at the chapters and demonstrate them with appropriate examples. Persistence is to insist on 3-5 questions every day!
