In 2012, I went to graduate school and asked about math three Thank you there are points.

You can read the syllabus for yourself, as LS said, and I can recommend some of the study materials to you. First of all, it must be a textbook, and you must lay a good foundation. While reading the textbook carefully, understanding the theorems of example problems, and doing after-class exercises, you will have a great gain.

Secondly, after reading the textbook, it is recommended to take a look at Li Yongle's review book, which is the thick one, consolidating and consolidating the foundation. After finishing doing Li Yongle's 660 questions, although they are all choices and fill in the blanks, they must not be underestimated, the basics. In the end, you should improve, do 400 questions, that is more difficult than the real question, it is recommended to do it, don't be discouraged.

When the exam is about to take place, I will do the past questions by myself and test the test. Then look back at the questions you did wrong, and you don't have the knowledge you fully grasped. Hehe, all hands played, I hope it helps you.

Textbook, 5th edition of recommended statistical textbooks for high mathematics, 4th edition of recommended statistical textbooks for linear algebra, the one in purple skin, the probability is used in Zhejiang University, a small book in blue and white skin, which is relatively thick.

This year's syllabus has just come out, you can buy a copy of the syllabus to look at, study or review the syllabus, here because the content is too much, there is no way to say.

First of all, you need to look at the exam syllabus, which can avoid detours and review things less.

As for the postgraduate entrance examination books, I think that if the foundation is poor, you can first find the basic postgraduate examination books to review the first round, and there are such books in various bookstores. It's much the same, almost, choose one that suits you.

Then you have the foundation, and then look at some improvements, or participate in tutorial classes.

Or directly participate in the tutorial class for basic learning, and the teacher's summary is always better than what you see.

Math III is generally divided into three parts:

Calculus (textbooks are generally Advanced Mathematics, Tongji Edition, Sixth Edition, Higher Education Press), Linear Algebra (Engineering Mathematics, Linear Algebra, Tongji University, Higher Education Press), Probability Theory and Mathematical Statistics (Zhejiang University, Fourth Edition, Higher Education Press), are generally these textbooks for the national examination.

The other three parts account for 56% 22% and 22% respectively

There are 123 past questions and explanations of postgraduate mathematics for graduate school entrance examinations, and if you have any questions about Hongyuan, you can ask at any time.

In 2004, it was difficult to take the third entrance examination.

1. The significance of the postgraduate entrance examination

(1) Choosing to go to graduate school means choosing a not too leisurely lifestyle. The best and most precious youth time in my life is to squeeze the single-plank bridge for the graduate school entrance examination, and then experience three years or more of study life. Others can use the most precious time of their lives to earn income, acquire skills, learn about society, and savor life.

(2) The purpose of the postgraduate entrance examination is to seek greater and better development space for the socks. With the advent of the era of knowledge economy, it has only become the primary productive force, and education itself is a kind of input and a kind of productive force.

2. Precautions for postgraduate entrance examinations

(1) Decide whether to be admitted to the graduate school of this university or to the graduate school of another university. Of course, the better the school, the larger the general development platform, but the advantage of this school is that you can understand the tutor in advance, contact the tutor, and the difficulty of the postgraduate examination is much smaller.

(2) Start reviewing professional courses. Contact the tutor and you can start to review the professional course, ask which professional course is to take the exam, which reference book, there will be a promotion in the school, and sometimes you can buy the real questions of the previous postgraduate professional courses in the school.

In 2011, the major questions of the three high mathematics in mathematics generally continued the previous idea: to test the candidates' calculation ability and ability to comprehensively apply knowledge. The overall difficulty is not large, the foundation is solid, and well-trained candidates can get relatively ideal results.

Among them, question 15 examines the calculation of the extreme limit, and the overall difficulty is low, as long as the candidate can skillfully use the very commonly used rules of calculating the limit, such as equivalent infinitesimal substitution and Lopida's rule, he can quickly get the correct answer.

Question 16 comprehensively examines the conditions for taking extreme values of binary functions and the operation of partial derivatives. This question also continues the consistent idea of the partial derivative brother Tong exam questions: the calculation process is more complicated, and the basic skills of the candidates in calculating the derivatives are examined, and the proficiency and accuracy of the candidates in solving the questions are required.

If candidates do not pay attention to this kind of question when solving this kind of question, they may make mistakes, and it may also affect the answers later, so they should be careful in their calculations and ensure that their thinking is clear.

Question 17 examines the calculation of indefinite integrals, which is also a more conventional type. In the calculation process, the partial integral method of indefinite integrals is mainly used. As long as the candidate has carried out systematic practice on indefinite integrals during the review process, it should not be difficult to solve this question.

Question 18 examines the discussion of the number of roots of equations, combining the application of derivatives with knowledge of the properties of continuous functions on closed intervals. When solving the problem, you should first use the derivative to find the monotonic interval of the function, and then use the medium theorem of the continuous function on the closed interval (the zero-point existence theorem) on each monotonic interval to prove the conclusion required by the problem. This kind of question has not been tested for many years, and many people have not reached it.

But in fact, it is also the application of this basic idea and basic method, and it is not very difficult.

The last big problem of higher mathematics is relatively new, combining double integration and differential equations. When solving the problem, candidates need to first use the calculation method of double integrals to convert the inequality of the double integral given in the question into differential equations, and then use the solution steps of the corresponding type of equations to solve them. This question tests the candidate's basic skills in the two parts of double integration and differential equation, and because the question is more comprehensive, it may be difficult for candidates who are not comprehensive enough to review.

Generally speaking, the propositions of this year's mathematics three advanced mathematics questions are still relatively conventional, emphasizing the foundation and highlighting the important and difficult points required in the exam syllabus. Candidates should still focus on the foundation when reviewing, do more exercises, and lay a good foundation for the basics.

Math III exam.

1.Subjects: Advanced Mathematics, Linear Algebra, Probability Theory and Mathematical Statistics.

2.Focus: To see the 2012 postgraduate mathematics syllabus, it should be found on the Internet at that time, now if you want to prepare for review, it is best to refer to the 2011 syllabus on the Internet, generally the change in the mathematics syllabus every year is not particularly large, so you can temporarily refer to the previous syllabus.

3.Reference textbooks: It is recommended to use the fifth edition of Tongji "Advanced Mathematics", with a green cover; Engineering Mathematics - Linear Algebra (5th Edition), Tongji University; "Probability Theory and Mathematical Statistics" by Zhejiang University Press is very rich in content.

4.Review materials: It is recommended to read more books at the beginning of review, read thoroughly, and lay a good foundation; In the intensive stage, you can use Li Yongle's large book review guide; Finally, you can do mock questions and related materials.

Calculus can be read in the book published by Tongji, which is very classic. Line generation and probability theory are just casually watched. It is recommended to buy Li Yongle's for the review of the whole book, and it is recommended to buy him for the later exercises and the analysis of the real questions.

Its practical books are not very important, the key is to have perseverance! The first time you read the whole book, you may not feel it at all, don't give up, after reading it 3 times, you will feel it, and then you will do the exercises, the real questions are very important.

I myself started to review in June, in fact, the key is to look at the efficiency, don't be discouraged if you can't do the topic for the first time, you will do more, and the success will come naturally!

The number three in 2014, frankly speaking, the title is difficult.

First of all, in the first multiple-choice question, the current answers of various institutions are different on whether to choose A or D; The answer to the third cross-test version will not be done directly empty, and the seventh and eighth questions are also difficult. The unbiased estimation of the last question of the fill-in-the-blank question, this knowledge point is not in the 2013 syllabus, and major institutions have not reminded candidates to pay attention to this content; For the fill-in-the-blank question of the quadratic standard type, the method of finding the eigenvalue with the feature determinant is completely invalid, and the matching method must be used to solve it.

The limit of the first question of the big question is very disgusting, requiring a very good understanding of the equivalent infinitesimal and Robida, and many candidates end up with a 0 answer, which is wrong.

Many candidates can't write the double integration of big questions just by doing sin sincos, which actually involves the content of elementary mathematics about the sum and difference products. In addition, in 2014, a rare problem of differential equations and a large problem of infinite series were examined, both of which were not given in vain. The answer to the cross-examination version says that the big question s(0)=3 of infinite series is wrong and should be 0.

In addition, although the topic of linear algebra probability is decent, there are also ditches and hurdles, and it must be reviewed comprehensively. Linear Algebra and Advanced Mathematics each have a proof problem, which was not possible in previous years, indicating that Mathematics 3 has also begun to emphasize the thinking of logical proofs.

In general, math in 2013 was easier, so it was difficult in 2014, and it is normal to estimate that the average math score in 2014 is 5-6 points less than that in 2013.

It feels easy. The main goal of the intensive sprint stage is to be familiar with the types of postgraduate examination questions, strengthen the connection between the knowledge points, distinguish the important and difficult points, shorten the review cycle as much as possible, grasp the overall knowledge system, and master theorem formulas and problem-solving skills. The syllabus of the examination has three levels of understanding, understanding and knowing the requirements of the content, and there are two levels of mastery and will be able to master the requirements of the method.

In previous exams, there is a high probability that this aspect of the exam will appear. Some information about the postgraduate entrance examination mathematics three can be found on the master's examination forum, you can go to see.

Mathematics 3 is an easy subject in graduate mathematics, much easier than mathematics 1, and 0 basic learning only needs to understand concepts and basic principles and skills, and can be admitted. However, you should pay attention to the registration of classes, you should apply for a tutoring class that is suitable for your level, many tutoring classes are open for people with a certain foundation, and it is best to choose a tutoring class for the basic level. In fact, it is best to have someone to guide you alone, because math three is not difficult, and it is very beneficial to have a friend who is good at science and engineering mathematics and is not going to graduate school to help.

Amateur players should first choose rackets with different strengths according to their own conditions and different playing styles: Baseline players: Amateur players who like to stay on the bottom line pay more attention to the stability of the baseline and a certain amount of attack power, and are suitable for using rackets with heavier heads and higher power levels Active offensive type:

It is suitable for rackets with a large weight, a light head, and a low power level, which helps to fully exert force and stability when attacking actively. Serve net type (or doubles), etc.

The difficulty of Mathematics 1 and Mathematics 3 is comparable, why do you say that?

1. There are many knowledge points to be examined by the number one, while the difficulty of the number three questions is higher.

Some students will feel that mathematics is difficult because mathematics will test more knowledge points. In the syllabus, the number one requires mastery of 285 knowledge points, and the number three only requires mastery of 173 knowledge points, which requires students to be proficient in more knowledge points.

Compared with Mathematics 1, Mathematics 3 requires less knowledge but a deeper depth of investigation, that is to say, although there are few knowledge points, it is necessary to be proficient in using it and know how to draw inferences from one example.

2. The focus of the investigation content is different between the number one and the number three.

Although the contents of Mathematics 1 and Mathematics 3 are all three parts: advanced mathematics, linear algebra, probability theory and mathematical statistics, and the proportion is % and 22%, the focus and some knowledge points required to be mastered are different, which also causes a certain difficulty difference between number one and number three.

The number one exam focuses on infinite series, curves, and curves, which is compulsory every year, and is often tested in the form of answering questions; In 2015, the problem of marginal cost and elasticity was examined in the form of a solution question, in 2014, the question of marginal benefit was examined in the form of a fill-in-the-blank question, and in 2013, the question of marginal profit was examined in the form of a solution question.

In addition to the difference in key knowledge, some of the knowledge points required to be mastered are also different.

In Advanced Mathematics, Mathematics 1 examines the physical applications of spatial analytic geometry, multivariate function integration (other than double integral), and calculus. Number three examines the economic application of calculus, and the number one is not examined.

In Probability Theory and Mathematical Statistics, the scope of the Mathematics 1 exam is slightly larger than that of Mathematics 3, and the test points of the parameter estimation part are mainly added, including the selection criteria of estimators, interval estimation and subsequent hypothesis testing.

Sum up. The difference in difficulty between Mathematics 1 and Mathematics 3 is relative, and some students will think that Mathematics 1 is difficult because Mathematics 1 requires more knowledge points; Some students think that the trilemma in mathematics is because the topics of mathematics three are more biased and in-depth. Therefore, the difficulty of Math 1 and Math 3 is comparable.
