150 points! 2012 Graduate School Entrance Examination Personal Complications About Mathematics Revie

Personally, I think: 1) You should calm down now, and you can feel your panic from your words, which is a big taboo in the graduate school entrance examination. Time is not a problem, as long as you put in it, maybe you can spend three months more efficiently than they put in a year.

2) Advanced mathematics is the main part of the postgraduate mathematics, and we should focus on this. Chen Wendeng's review guide is too heavy on skills, and I personally think that Li Yongle's review of the whole book is better. When I first started doing it, I didn't know anything and panicked, but after doing it twice, I felt much better, and I understood the basic idea and everything, so I think you should review Li Yongle's whole book at least twice, of course, according to the outline.

3) I think you can do a few sets of past papers now to understand the general type and difficulty of the questions, so that you can focus on them when you review. Actually, I don't think the difficulty of the real questions is very large, and they are generally based on the basics, so if you are really short of time, you can not read the more difficult questions on Li Yongle.

4) The line generation handouts are very good, you have to read them two or three times, don't read the line generation in Li Yongle after reading this, or just pick it up and take a look. Generally, there are only a few test points in linearity, and it is generally no problem to do more. Also, I don't think 660 is as good as what is said outside, anyway, I think there are difficulties and biases, and this is up to you to decide

5) In terms of time, I think I should spend at least 10 hours a day on the graduate school entrance examination. It takes five hours for math. It's better to read math in the morning, at least two or three hours at a time, if you are dizzy at noon, it is recommended to look at English or something, and spend another two or three hours in the evening to continue to read math

In the future, it will be my personal experience and advice, but it will be combined with yourself, hehe, good luck

After looking at your situation, according to my experience, I will tell you first, don't worry, there is still time, 3 months, enough!

First, I personally think that Li Yongle's problem solving is more skillful, I used to buy Li Yongle's books, and I asked those who read Chen Wendeng's books if I didn't understand, and they didn't understand, so I gave up Li Yongle's books, bought Chen Wendeng's, and started reading books at the age of eleven, reading mathematics for 8 hours a day, and reading it again in less than a month, and finally reading it three times, and the math test was not bad, hehe. So don't hesitate to choose one according to your own opinion! Personally, I support you to read Chen Wendeng, and stop reading those notes from your class, which is similar to reviewing the whole book.

Second, you don't need to do any other questions now, just read the whole book three times and prepare for it.

Third, buy a copy of Li's real question analysis, there are 135 points, the real question is to do it as many times as possible, 135 points is to increase the problem-solving skills, you can take a look at it when you have time.

Fourth, it takes one month to complete a review book, the second time in half a month or 20 days, and the third time in half a month.

Fifth, it is best for you to use 7 or 8 hours in the next month to complete the first review, and the rest of the time can be used to watch professional courses, after the first time, the time for mathematics can be reduced according to your specific situation, but you should read mathematics every day!

Personal experience summary, the following points should be paid attention to in the process of advanced mathematics review sprint:

1. Regarding derivatives and differentiation, the focus of the exam is on the definition and application of derivatives, that is, the derivability of abstract functions. It is also necessary to be proficient in the methods of finding partial derivatives of various multivariate functions, as well as the solution and application of extreme and maximum values.

2: About the points part. Finding various integrals, such as definite integrals and indefinite integrals, is an important type of problem.

3: Differential equations, as well as infinite series, summation of infinite series, etc. Note that there are many formulas and theorems that need to be memorized.

The methods for solving equations in differential equations where variables can be separated, homogeneous differential equations, and first-order linear differential equations are very important, as well as for solving second-order linear differential equations with constant coefficients.

4. Linear algebra: inverse matrices and the rank of matrices, linear correlation of vectors and linear representation of vectors, correlation of vector combinations, discussion of solutions of systems of equations, properties of eigenvalues and eigenvectors, and diagonalization of matrices, judgment of positive definite quadratic forms.

The coherence of each chapter of linear algebra is relatively strong, and when we review and summarize, especially in the later stage, we should have a summary by ourselves, and form a knowledge framework for the knowledge points of linear parameters in our minds.

5. Probability theory: the nature of probability and the formula of probability, the distribution of one-dimensional random variable functions, the joint distribution and marginal distribution of multi-dimensional random variables, and the conditional distribution, the numerical characteristics of random variables, and the maximum likelihood meter in parameter estimation.

I wish you success!

You are a bit similar to me back then, I started the graduate school entrance examination at the end of September of that year, and I basically had no foundation in mathematics, and I was a gangster in my undergraduate. Later, I bought a handout for the intensive class of a well-known tutoring class in Hefei, which is only one-third of the thickness of the whole book of mathematics tutoring, and it is the content of the common exam, which is too difficult or unlikely. It's hard to get above 130 by that, but if your expectations are around 110, it's perfectly sufficient.

I counted 101 back then, and I felt that if I read another compilation of exams above 110, it should be no problem. I don't think enough time is enough to read the whole book now. You have to read a book three times, otherwise it's useless if you forget it.

If you have any specific questions, just hi me.

It will be very helpful for you to take a look at the postgraduate entrance examination in the tutorial class**. There are many tutorial classes including New Oriental, Wendeng, Wendu, Haitian, Qihang, Enbo, etc., which include the whole course from basic to intensive to sprint, and the courses are updated synchronously with the tutorial classes of the year. The latest postgraduate entrance examination **course has been fully updated and launched, and a postgraduate student must go**!

Check the syllabus from the graduate school of this school, but last year's can't decide this year's, and this year's syllabus should be paid attention to again, but it will definitely not be wrong to review advanced mathematics at present, because all mathematics must be tested in advanced mathematics.

This depends on the requirements of the school, some of them are three, some of them are one, and the general engineering class is one of them, and you still have to pay attention to the requirements of the school

1, Li Yongle's books can be read, some questions have not been tested in previous years, it does not mean that they will not be tested this year, so it is foolproof, or take a look, it is best to do them all again.

2. Start doing the real questions, and review while doing the real questions, which is more efficient.

3. Yes, the proportion of advanced mathematics in postgraduate mathematics is always the largest, followed by line generation, and finally probability, but it must be reviewed.

4. If you haven't achieved a qualitative change, then do more questions, do more real questions, I am from the Department of Mathematics, I did a lot of real math questions when I was admitted to graduate school, and almost all the review materials I bought were done, and after doing it, I had to copy down the questions and see if I would do it, not only to do it, but also to think more about why I did it.

Hope it will help you.

Personally, I think that Li Yongle's whole book is just to refamiliarize himself with what he has learned before, and it is definitely not enough to just read the whole book for graduate school entrance examinations. It is recommended that you do the past questions now, and summarize the question types by yourself when you do it.

Assuming that the 20 people who didn't pick were all known by the 80 people who were picked, then there was a possibility that the least number of people who knew each other would be the least likely to know each other.

That is, among the 80 people, the 29 people who don't know a person are all in these 79 people, then this person knows 50 people, but these 50 people don't necessarily know this person, maybe this person is one of the 29 people he doesn't know, and the most that appears is not the number of people who know each other may be that one person knows another person, but the other person doesn't know himself, so it is assumed that the 30 people who appear know the same 50 people, but the 29 people who don't know these 50 people are all in these 30 people. And if the remaining person doesn't know the 29 people are in 50 people, then there are 21 people who know each other with him, so 50 people know each other in pairs, and the remaining one and 21 know each other, since the number of people who know each other can't refer to one person alone, every combination of two people counts one, that is, there are c 2 50 + 21 kinds, that is, 1246....The brain is a little messy, uh, don't think about it, so be it.

Know each other? Does it mean that everyone in the collection knows everyone in the collection except himself?

Or do you know me and I know you, so you know each other?

Well, out of 100 people, 29 people know any 70 people among the other 71 people, but they don't know each other. And then the remaining 71 people, knowing each other. Of the 71, 50 knew each other, but did not know the remaining 29.

So there are two parts of these 80 people, one part is 51 people, who know each other; One part is 29 people who don't know each other. But these 29 people knew at least 50 of the other 51 people, and none of the 51 people knew these 29 people. In the end, the unrequited love situation of these 29 people was formed.

So at least 51 people knew each other.

Is that so? Why are there two same questions?

Ok, that's the answer. Let's give a reaction.

100 people Everyone knows any 70 of them, and there are 30 people who are not known to everyone, so how many of the 80 people know at least how many people should include these 30 people who are not known by others, then 50 should know each other. Thinking about this for the time being, I haven't figured it out too much, hehe.

If you don't give the problem, people with high intelligence can't solve it! What should you do with this problem? Let's be realistic! Send you a sentence after the break, pull the carriage on the wall, and it is difficult to kill Raff (Yugoslavia).
