Mathematics is not difficult, even mediocre people can become masters! Are you a mediocre person? Of course not, so you can be a top player!
About reviewing the early stage of mathematics (about two months), three words, passing the textbook! Of course, to choose the best teaching materials, it should be recognized as: Tongji's high number, the probability of Zhejiang University, and Tongji's engineering line generation. Pass a book.
I don't remember, but I understand. The derivation of the theorem must be seen, but you don't have to do it all after class. Of course, reading through the textbooks must be based on the contents of the examination syllabus, otherwise, if the probability in the second half of Zhejiang University is
If you have seen it, you will lose a lot! Don't buy an outline, it's a waste! Just download one online!
After going through the textbooks for a long and boring time, buy a tutorial book for postgraduate entrance examination and recommend two books: Li Er's Review Book or Mr. Chen's Review Guide. Li Er's books are simple and simple, while Chen's books are chic and chic.
As for skills, you can choose one according to your own situation.
Start doing the examples in the tutorial. From beginning to end, you can't miss it, you can't distinguish between primary and secondary, you should treat it equally! I believe that when you do the problem, you will find the theorems and formulas you have seen before very depressed.
Nine times out of ten, forget the light! Don't panic, this is completely normal! If you are not like this, you may be Huang's wife, or Superman, or not human at all! Therefore, we must treat the objective forgetting law correctly.
, can't lose confidence. When doing an example, I found that I forgot the necessary related formula theorems. I'll go back to the textbook to check for leaks and fill gaps! Forget to make up again! Going back and forth three or four times may not be forgotten for three months; back and forth
Seven or eight times, you may not forget it for three years!
Treat examples, you can't just look at them without doing them! Because everyone who watches TV plays has the ability to guess the next story, but not everyone can write a script! Don't read the analysis unless you have to, you know.
Only by doing it yourself and then checking the answer, this feeling is the most fulfilling! After reading and analyzing the questions that you really can't do, mark them with RMB symbols to remind yourself that this problem may affect you.
Only when you have money can you motivate yourself to focus on the next round!
When you have honestly done the examples in the tutorial for two or three times, congratulations! You have come out of the most difficult period of math review! Next, your review will become easier and easier. Now you should
Put down the counseling book and buy a real book to do over the years. There is no need to recommend. The real questions on the market are evenly matched, and they are all masters! You can start from the last one. Every two days, no simulation, after all, the 90 s.
The original real questions are very simple, and some of them should have been done in the postgraduate counseling book. Therefore, this process is a process of getting familiar with the real questions, a process of deepening the review of knowledge points horizontally, and a process of increasing confidence.
Cheng! But it should be noted that don't look down on your superiors, encounter simple problems, and don't think you know the methods and processes and just skip them! Remember, this is very deadly! ! An obvious example is finding eigenvalues in online generation.
Process, don't think that this is essentially just a simple problem of finding determinant, in fact, the skill accumulation of extracting common factors through determinant transformation is the most important.
The study of the real problem is over, comrades. If the postgraduate entrance examination is steak, you should be seven mature now! We must start the sea tactics! Objective To strengthen actual combat and cultivate experience. Many people are against this model.
It is actually lazy to advocate the sea tactics of changing with the constant. Last year, I only got 87 points in math, not because I didn't review well, but because I didn't care about the importance of simulation. It's like driving in winter.
You must start the engine to warm up the car first, or you may have an accident. If you want to avoid the accident of panic and power failure in the examination room, the model sea tactics are very important! ! I believe many compatriots have already experienced it in the examination room this year.
To some helplessness! In my opinion, whether you carry out the tactics of modeling the sea is related to whether you can pass the exam above 120. The mathematics we learn is not the deep work of doing research, but the skilled work of coping with exams! boil
How to practice without relying on a lot of training? We must pass a large number of mock exams in order to be well informed and form the conditioned reflex and mindset needed to get high marks in the exam. We must achieve this goal.
As soon as the title of realm is pouted, you will know what shit you are pulling! Only in this way can we save time, be quick and accurate in the real exam. In fact, the implementation stage of the late mode sea tactics is purely one.
A relaxed enjoyment stage, when you give yourself extra points for each set of simulation questions, it is as cool as counting money! At least I think so! In that case, why not make more molds?
In 2004, a senior who passed 146 told me that he had done more than 80 sets of simulation questions back and forth. It should be noted that the choice of simulation questions is very important. Remember to choose one for each member of the proposition group.
Try not to choose a well-known tutor to write the simulation questions. The really good simulation questions are those that are spiritual but not unfamiliar, wide but not deep. Let's have a good experience and don't fall into the misunderstanding of pursuing difficulty. I put the used model.
The proposed topic is recommended to you for the postgraduate proposition prediction test paper (No.X)(20 sets) of Intellectual Property Press; 8 sets of test papers for testing worms and prediction papers for black blogs (15 sets); Black Wave Final Composition Paper (AB*** 10 set); Hefei gong
The last five volumes in the last two years of the postgraduate entrance examination class in University of Technology (*** 10 sets). It should be said that these simulation volumes are closer to the real style than other simulation volumes, especially the last five sets of volumes in the postgraduate entrance examination class of Hefei University of Technology.
Family members must pay attention to it. Personally, I feel that the big questions inside should all be new questions selected from the question bank, and they are almost not repeated with the simulation questions sold in the market. Everyone should look for them online or try to learn from them.
Classic simulation questions like this can't be bought in bookstores. I have done Li Yongle's 400 questions, but I don't regard them as simulations, but study them as examples in order to improve them. After all, I think
I feel that 400 questions are too difficult. The first two groups each worked for nearly 4 hours, and none of them exceeded 90. Strike!
Speaking of which, some friends can't help asking if it's time to talk about remedial classes. My opinion is-useless. Especially those so-called tutorial classes, because of their great fame, have more people than that.
Many, the class environment is extremely poor. One of my classmates went to Beijing for a postgraduate tutor's class in the summer vacation. When I came back, I asked him what he had gained. He told me with a sad face that the classroom was full of stocks.
Smelly feet, how can you bear to attend class? I told him that even if there are flowers all over the room, you may not be able to listen to the class well-you just have to take notes! It is better to save money and eat more big chicken legs! In addition,
In addition, it is precisely because the teachers who give lectures are famous and there are too many places where teachers are invited to give lectures, so a conscientious tutor can't devote himself wholeheartedly. When I say this, I don't mean to deny the role of remedial classes. In fact, this is the case.
The experience of some masters is certainly useful for our review, but it is only useful in theory. If you really want to listen to the teacher, you must finish reading the book first. Why not surf the Internet in another way?
Listening to online classes has many benefits. At least, you don't have to smell your smelly feet, be disturbed by the outside world, or be afraid of the teacher dozing off on the podium. More importantly, you don't have to write notes hard, you can take your time.
Listen and digest slowly. If you don't understand, you can go back and listen again. Sailing, Education Online and New Oriental are all very good. In my opinion, the postgraduate counseling book is the best teacher, and it is the best to continue reading.
I can talk about it anywhere I want according to my own schedule and plan. Remember! The role of remedial classes is to assist treatment, and it can never be a specific medicine.
After talking about the macro aspect, it's time to talk about the micro aspect. I summed it up as "five musts"
You must thoroughly understand the basic concepts! Never drag your feet and be vague. One is one, one is two! For example, what can be called the basis of the solution of the system of equations? There are four 1, and the solution of the equations is 2 linear none.
The number of off 3 is n-R(A)4 nonzero. All four are indispensable! For another example, when learning the gradient, divergence and curl of high numbers, it is necessary to make it clear that the gradient is a scalar vector; Divergence is a scalar of a vector; Curvature is a vector of vectors.
For example, the distribution function in probability stipulates that it will always be right continuous = when representing the interval, all factors with equal signs should always be written on the left (sometimes there is an equal sign factor on the right as a special case of its overall continuity). concept
Always the foundation, always the cornerstone. Don't be eager to be Liu Xiang until you learn to walk!
Be sure to sum up the method! It is also very important to write down every new experience and method in your notebook! For example, there are generally no more than seven ways to find the limit 1. The numerator and denominator are multiplied and divided by two variables.
Substitution of three non-zero factors 4 Robbie's answer 5 equivalent infinitesimal 6 pinch 7 Taylor formula. Another example is the convergence and divergence discrimination method of sequence 1 general comparison method 2 limit comparison method 3 ratio method 4 root method; Another example is linearity.
Algebra includes 1 definition (recombination by multiplication or division), 2-rank discrimination, 3-homogeneous equation AX=0, only zero solution, 4-reduction to absurdity, etc. It should be noted that the more methods advocated, the better, but
We don't need to delve into what is not in the textbook and what is outside the textbook. For example, some postgraduate counseling books introduce differential operator method to solve differential equations. I don't think it's necessary to memorize it. After all, this method.
This method has its limitations, and it cannot cover all the contents. If you are addicted to this skill, the topic of the exam happens to be its blind spot, then you will lose a lot! Some books also introduce the tabular method of distributed integral, which is really fast, but it is also
There are limitations, it is not easy to use flexibly, and the general method is not much slower. Why bother? Therefore, when summing up the method, it is not much, but it is fine. The core is to help you solve it yourself.
Test habits make it easier for you to overcome test questions.
Knowledge must be integrated! For example, if two square matrices are equivalent and similar, what is the necessary and sufficient condition of the contract, that is, equivalence = the rank of the square matrices is the same; Contract = The positive and negative inertia indices of a square matrix are the same.
Grade equality is only a necessary condition of contract; Four properties of similar matrix (same eigenvalue, same rank, same determinant, same principal diagonal sum) are all necessary conditions for its establishment, such as interval estimation and false probability.
Let's just say that the test is different and pure. For another example, the square matrix A is reversible = the equation AX=0 has only zero solution =A can be expressed as the product of several elementary matrices = The row (column) vector group of A is linearly independent = The determinant of A is not.
Zero = full level. These knowledge points need to be summed up and strung together horizontally, so as to achieve mastery through a comprehensive study, so as to better understand and remember. The principle of mastery is embodied in linear algebra at most.
Surface, it can be said that every chapter, every knowledge point has direct or indirect contact with other parts. You can't learn linear algebra as a whole!
Be sure to focus on the points that are easy to forget and pay attention to mistakes. This is one of the most effective ways to avoid low-level mistakes in the exam, such as the distance formula of two straight lines, the curvature formula of curves and strokes.
Jones formula, Taylor formula and so on; Basic formulas related to several matrix equations in line generation, basic coordinate transformation formula (left-right distinction) and so on; Several limit theorems of probability law of large numbers and several distributions of statistics.
The direct application formula of probability density of functions and variable functions (addition and multiplication) (focusing on the conditions for their use and the determination method of integral limit) and so on. These formulas are difficult to remember, so read them more and keep them at any time.
I mean, in the constant proficiency of doing the problem, I try to deepen my memory. The key point is to remember the points that are easy to be confused and omitted. For example, when using rectangular coordinate method to transform horizontal coordinate method in double integral, don't forget multiple R factors.
When calculating the general term of vertical leaf series, don't forget to divide a0 by 2 when writing the general formula. Don't mix orthogonal matrix with positive definite matrix, and so on.
We must pay attention to cultivating our own mentality. This is the only guarantee that we can eliminate all problems in the shortest time after entering the war in the future! ! For example, if you see AB=0 in row generation, you should immediately think of the column of 1. B
All vectors are solutions of equation AX=0. 2. r (a)+r (b) = n (number of rows of a or number of columns of b). For example, if the word 1 is mentioned in the probability topic, you should immediately think of the method of 1-(that is, the probability is zero);
For example, the problem surface with high number has second derivative, so we can consider using Taylor formula to solve it first, and so on! In fact, many counseling books have summed up some mentality, plus their constant proficiency, there are many.
This mode of thinking has been subtly rooted in your own mind.
Speaking of which, it's time to talk about sensibility. On the day of the exam, you must pay attention to the following points.
1. Treat yourself with incorrect questions. As the saying goes, man proposes, God disposes. Even with the best preparation, no one can guarantee that the exam will be smooth sailing. Remember one thing: never let your
There is a blank space on the paper! Don't give up every point on the paper at will. Those questions that cannot be started or forced to give up must be filled in for the last time. Push down from the known
A few steps, then push up a few steps from what you want, use all the theorems you can touch in the indirect part, and then continue with "obviously available", so that the problem of 12 can't be done at all.
You can get three to six points.
2. Answer the question with a blue pen, never with a black one! Be sure to wait for the mood of the marking teacher. Everyone should understand this truth!
3. Be sure to master the time! Among the three courses of advanced mathematics, line generation and probability, probability is the simplest, followed by line generation, and advanced mathematics is the most difficult. Fill in the blanks, choose, and fill in the blanks with big questions is the easiest, choose the second, and the big questions are the most difficult. so I ...
I suggest you fill in the blanks for about 50 minutes, then do the last two high probability questions for about 20 minutes, then deal with the two large linear questions for 20-30 minutes, and finally set aside one.
Do those five big questions in about half an hour.
I am confident that if the above methods can be implemented in my review, becoming a master of mathematics will no longer be just an illusion! Finally, remind everyone that in the process of math review, no
Pay attention to your current level! Self-confidence is important, and conceit is unacceptable. You can't think that you are almost finished, it's time to have a rest and have careless thoughts. You can't recite too much.
Burden, can not correctly face the long road of math review. Remembering math anytime and anywhere is like washing clothes in a dark room. You never know if your clothes have been washed.
All you have to do is rub and rub with the best washing powder!
