The books written by postgraduate entrance examination experts are different in difficulty and way of thinking, and candidates can choose materials that suit them according to their needs. For example, Li Yongle's book pays attention to the basics and its content is simple and easy to understand. We think that "Analysis of Mathematics Examination Questions in the National Entrance Examination for Postgraduates" and "Analysis of Mathematics Examination Outline in the Unified Entrance Examination for Postgraduates" compiled by the Examination Center of the Ministry of Education are very close to the examination requirements and are good review reference books. There is not much information, the key is to see through and digest.
How to review the topic of applying theoretical knowledge to solve practical problems in postgraduate mathematics, and what are the general skills?
This is a very important feature in the mathematics examination in recent years, and there are similar questions almost every year. It requires candidates to abstract some geometric, physical or other problems with uncertain scope into mathematical problems (also known as establishing mathematical models), and then use corresponding mathematical knowledge to solve them. Since 1997, science and engineering students have taken an examination of pollution control, pressure calculation, steam hammer work, aircraft taxiing and other issues. In order to solve this kind of problem better, candidates should pay attention to reviewing the following knowledge points: tangent and curvature of curve, directional derivative and gradient, extreme value of function, application of integral calculus in geometry and physics, establishment and solution of differential equation, etc.
Students who have experienced the postgraduate entrance examination in 2009 should know that this year's situation can be said to be a single-plank bridge. Due to the economic crisis, many students choose to take the postgraduate entrance examination, so the competition will be fierce. If you want to succeed, you must have a clear goal, a good set of methods and a reasonable plan. Nowadays, many students are unemployed because they have not made these preparations, and graduate students have temporarily become a bubble, but they have to take many detours.
I am a part of one of the postgraduate entrance examinations. I am a student of the School of Mechanical Engineering of Huazhong University of Science and Technology, and I also applied for this major. I got political 64, English 6 1, math 14 1, major 133, with a total score of 399. Looking back on the process of postgraduate entrance examination, I have a deep memory of math review, and math is where my grades can be improved.
My review started very late. I didn't start reviewing until the new school year started in September 2008. Compared with other students, I was much behind in my progress, and I was still very anxious at that time. But I still have a general understanding. There are four subjects in the postgraduate entrance examination: politics, English, mathematics and major, among which mathematics is the most important. Some people say that "those who get mathematics get the world" fully illustrates the importance of mathematics.
It took me nearly two months to read the 600-page counseling book, but in retrospect, it is still worth it. By June 1 1, I felt that I had finished reviewing the basics of mathematics and started to do comprehensive tests, but I encountered unexpected difficulties at this time. I didn't feel anything when I did the problem, but I didn't know the key points. Sometimes I can't remember the basic formula, especially the line generation, which is very logical and comprehensive, which makes me very confused and once had the impulse to give up.
At this time, I want to manually adjust and deduce a formula in the math course on paper. Although this is mechanical and seems to be a waste of time, it makes me remember the basic theorem and apply it accurately and quickly, further consolidating my mathematical foundation. Because all the chapters in linear algebra are closely related, these formulas are all strung together. Suddenly, I have a feeling of being opened to the second pulse of Ren Du, and the frame generated by the whole line emerges in my mind. Looking back now, paying attention to the foundation is a key to the success of those who took the postgraduate entrance examination in 2009. Probability is the least part in math review, so people generally don't pay much attention to it. There are many formulas and concepts.
65438+1October 1 1 morning, the math exam finally came. I did three high numbers first, then linear generation, probability, and the last two high numbers were to solve problems and avoid sharp changes in mentality. Many students just worked hard on the last two high numbers, which delayed a lot of time. This year's mathematics has a characteristic. In fact, the content of the exam is particularly basic, that is, many people don't pay much attention to it, and as a result, they suffer a big loss. Obviously, they are familiar with each other, but they just can't do it. Many students have not solved the linear related big problem of line generation. In fact, in the usual training, the problem is the same as the basic deduction in the book, but everyone thinks it is complicated and finally bypasses themselves.
So I suggest that we should pay attention to the basics when reviewing mathematics. Often the difficulty is the idea of formula derivation. I believe it will be of great help if we grasp this point.
