I believe all students know the fact that the proportion of advanced mathematics, linear algebra, probability and mathematical statistics in the first place is 56%, 22% and 22% respectively; The number two does not test probability and mathematical statistics, and the proportion of advanced mathematics and linear algebra is 78% and 22%; The proportion of three in number three is the same as that in number one, which is 56%, 22% and 22%. In fact, for No.1, No.2 and No.3, the emphasis of each subject is also different. Below, I will give you an analysis.
Let's look at advanced mathematics first. It can be said that the biggest difference between the three exams of advanced mathematics is to count one, two and three, and this difference is only manifested in the requirements for the scope of the exam, while the requirements for the ability of the exam have hardly changed. For example, for the limit, the number one, the number two and the number three must be tested, and the requirements for the test are almost the same.
For the number one candidate, the focus of our review is the second book, which means that the focus of the exam is multivariate function differential calculus, multivariate function integral calculus and series, and multivariate function differential calculus and multivariate function integral calculus will each produce a big question almost every year. Many candidates think the second volume is more difficult. In fact, everyone is completely wrong about this, and the first book is even more difficult. The knowledge points in the next volume often have a high starting point and a low landing point. Although each topic is more complicated, the methods and ideas for solving the problem are all the ideas and methods we have in the first book, and they are also relatively easy to master. As long as you master the idea, there is no pressure to get this part of the score.
The number two is the exact opposite of the number one. The focus of the exam for No.2 students is the first volume. That is to say, for junior two students, the test focuses on limit, differential calculus of unary function and integral calculus of unary function. In addition, the second topic is usually very flexible and detailed. This is because the proportion of number two in advanced mathematics reaches 78%, that is, 1 17 points. The scope of the second inspection is relatively narrow, which determines that the topic of the second inspection is very flexible and is often inspected in detail. On the other hand, the first volume of advanced mathematics is more comprehensive than the second volume.
The difference between three plus one is not very big. However, the topic of number three pays more attention to application. This is because most junior candidates are economic and management candidates. Therefore, the number three pays attention to application and needs to attract the attention of the number three students.
Secondly, let's look at linear algebra. The difference between one, two and three in linear algebra is not very big, so here I mainly tell you what the focus of linear algebra is. The similar diagonalization of linear equations and matrix is the focus of investigation, and we should also pay attention to the combination of linear equations and vectors, and the combination of similar diagonalization of matrix and quadratic form. Linear algebra takes two big questions every year, and often these two big questions are taken by these two knowledge points.
Finally, let's look at probability and mathematical statistics. For probability and mathematical statistics, there is almost no difference between number one, number two and number three. Similarly, I also pointed out the important and difficult points of the exam, hoping to help you. The edge distribution and conditional distribution of multidimensional random variables, random variable function, numerical characteristics and parameter estimation are all the key points, and the priority of the key points decreases monotonously. Especially the edge distribution and conditional distribution of multidimensional random variables and random variable functions are very important. For digital features, the possibility of doing a big problem alone is relatively low, but it is often combined with other knowledge points as the first question of a big problem. Finally, let's look at parameter estimation, a knowledge point. I hope the students of number one will pay more attention. The possibility of numerical one investigating the big problems in this section is still relatively high.
The above is the difference between number one, number two and number three in postgraduate mathematics. I hope I can help you.
Finally, I wish you all the best in the postgraduate entrance examination!
