High school sophomores looking to improve their math scores!!

First of all, adjust your physical condition, don't catch a cold and get sick and affect your studies;

Secondly, familiarize yourself with the textbook, read it with your heart, feel it, and study it, this stage is really pure reading of the textbook (grasp the beat by yourself, not too fast, and not one or two pages in half a day), it is best to take a time period to read the textbook, you should know what to read, we have a special evening self-study time at that time to allocate our own learning, the foundation is very important;

Then, you can find a reference book, which is authoritative and used by the public, and continue to consolidate the foundation according to the chapter order, do the following exercises, analyze the answers, and then buy a notebook, make a good summary, and consolidate the foundation is very important;

After that, find real papers and the like to do it, gain self-confidence, and do a good job of taking notes to analyze and summarize after completion, and broaden your horizons;

Finally, from time to time, I read the textbook, do the next question (be sure to broaden your knowledge), and look at the analysis and summary of the questions I have done wrong in the past. Look at the textbook (read more), do the questions on the real questions (do more), look at the notebook of your own analysis and summary (summarize more), and do the three in a cycle; This is a long-term process that should be adhered to.

And then there is no then, you can take the college entrance examination 148.

Teacher Meibo Education Zhou will answer for you: the grades are good and bad, it is that the basic knowledge is not firmly grasped, and you will do it when you encounter common question types, and you don't know the idea if you change the question type slightly, and then the teacher will fully understand it. At this time, it is necessary to consolidate the basic knowledge, after all, there is still a period of time before the college entrance examination, and then learn new knowledge at the same time, don't be like before, feel that simple is not very important, the basic knowledge is very simple, but the root of the problem also comes from the foundation, lay a good foundation, not only learn mathematics, is the way to learn all knowledge.

Hope it helps.

If you don't have a solid grasp of the basic knowledge and don't really understand some of the content in mathematics, it is recommended that you practice more, and then summarize it and summarize it yourself, the key is to summarize, record the wrong questions, and analyze the wrong questions, which is a slow process, and you must do it carefully.

First of all, the knowledge points must be learned in place, and the foundation is not laid, how can there be a qualitative leap. After the foundation is solid, you should do more questions, after-class questions, homework questions, exam questions, etc. Finally, there should be regular self-feedback ideas and self-examination.

Mathematics in the first year of high school is not very difficult, work hard and persevere, and there will definitely be a receipt.

Dear classmates, after reading your results, I can indeed see that you are in a hurry, but if you have the heart to improve, then everything is still in time. Based on your grades, I would like to give you the following suggestions, if you do well, you will definitely improve greatly:

1. Lay a good foundation. Judging from your scores, your foundation in each course is not solid, you must make a good study plan, especially this holiday to make a good study and problem plan, starting from the example questions and exercises in the book, if you can do the example questions and exercises in the book once, I believe that your basic knowledge will be consolidated and improved, science knowledge must be applied and understood, but memory is essential, if you don't even remember the basic formulas and equations, you can't talk about application, so start from the book, After completing the example questions and exercises in the book, it is best to draw inferences from one another, so that you can move on to the difficult problems! 75% of the college entrance examination questions are basic questions!

2. Listen carefully in class, whether you can understand or not, you must follow the teacher together, knowledge has continuity, you can only listen carefully, you will listen to the brain, you will slowly understand from not understanding to slowly understand, this is a step-by-step process, you can't give up, you can't be in a hurry, you must do your best to persevere, as much as possible to understand the knowledge, if you don't understand, you have to ask, ask the teacher and classmates, you must be bold to ask, make the knowledge clear, learn new knowledge while trying to review the old knowledge, In this way, you can better learn and understand new knowledge. In this process, you have to spend more time and energy than others to try to persevere.

3. The most important point is that you should take the initiative to learn, learn knowledge with a positive attitude, be able to affirm your progress, be willing to learn, and do problems, it is easy to remember knowledge. You can't be passively forced to accept knowledge, in that case, it will not be easy for you to memorize the most questions. There will be no learning efficiency.

No one can tell you which study plan is the best, you have to look at your current level, analyze the reasons and then make a study plan that suits you, and stick to it, make progress a little bit, I believe you will get better and better!

Find more practice questions to do seriously, let the teacher point out the point, don't be embarrassed. It's easy to get to the bottom of that. Believe you can do it.

No pain, no gain!!!

Listen carefully to physics class, thinking that if you don't listen carefully to physics, it will not be easy to make up for it after class.

Chemistry should be super familiar with textbooks and memorize more knowledge points.

Biology is OK as long as the class is serious, do your homework seriously after class, review the content of the class in class, and after the evening self-study, you can completely ignore it after class.

Mine is just for reference.

The industry is good at diligence and ridiculous in play, and the line is successful in thinking and ruined.

Solution: From the problem and Cauchy's inequality, y=[x+(1-x)][a x)+b (1-x)] a+b).

The equal sign is obtained only when x=a (a+b).

Therefore ymin=(a+b).

The function representation is not very clear.

If you want to make repentance (1-ai·x) 2 1, then -1 1-ai·x<1 then there is a lack of repentance.

2＜-ai·x＜0

0＜ai·x＜2

Inson's is a1>a2>a3>0

So 0 x 2 ai

Because f(x) = x 3 + ax 2 + 1

So f'(x)=3x^2+2ax

Substituting (1,b).

So 3*1+2a*1=-3, a=-3

f(x)=x 3-3x 2+1,f'(x) = 3x-6 req f'(x)=0, get x=2

x=2 takes the minima.

So m-1993>=f(4), i.e. m-1993>=17, so m>=2010

<> the case of cancellation and cancellation is as follows.

Is your question numerically correct?

The last formula you write should be a(n+1)-a1. If this is a fill-in-the-blank or multiple-choice question, algebra directly, find a2 when n takes 1, a3 when n takes 2, a4 when n takes 3, and a5 when n takes 4. This way the calculation will be fast.

7. Sixteen + sixteen times the root number fifteen.

Eight, three-thirds of the root number three.

9. Root No. 2.

10. Nine-in-half times the root number 15.

XI, X

XII. Two hundred and fifty

XIII. The root of the thirds is numbered thirty-five +

XIV.XVI

XV.III.

Count it several times! Tired!
