The focus of the calculation problem is not the amount of calculation and the complexity of operation, but the ideas and methods, such as the calculation of multiple integral, curve and surface integral, and the sum function of series. In addition to ensuring the accuracy of the operation, it is more important to systematically summarize the problem-solving ideas and skills of various calculation problems, so as to choose the simplest and most effective problem-solving ideas when encountering problems and get the correct results quickly.
Focus on the ability to analyze and solve problems.
First of all, starting from the conditions of the topic, make clear the goal to be solved; Second, establish the relationship between the conditions given in the topic and the goal to be solved, and integrate this relationship into the mathematical model (pay special attention to the choice of origin and coordinate system for graphic problems), which is also the most important link in solving problems; Third, according to the category of the mathematical model established in the second step, find the corresponding problem-solving method, and the problem can be solved easily.
Mathematics review rules for postgraduate entrance examination:
1, at the beginning of revision, you need to read through the math textbook first, mainly to understand and remember some important concepts and formulas. Of course, if possible, by the way, do some simple exercises, the effect is obviously better. These after-class exercises are very helpful to summarize some related problem-solving skills, and also help to recall and consolidate knowledge points.
2. Be good at summing up and thinking more. Summary is a good review method and a way to improve knowledge. While reviewing each knowledge point separately, we must contact and summarize, and establish a complete mathematical knowledge system structure for postgraduate entrance examination.
For example, when reviewing the knowledge points of integral, we should be able to establish the relationship between unitary integral, double integral and multiple integral, so as to deeply understand and master each knowledge point.
In addition, we must rearrange the problems and mistakes encountered in the basic stage, sum up our own weaknesses, and correctly solve the remaining problems through intensive training. There are more than 20 topics in mathematics for postgraduate entrance examination, and each topic has only a few types, which do not change much every year. As long as you are diligent in summing up, the postgraduate entrance examination mathematics is nothing more than that.
3. Of course, at each stage, you can't do less questions, read more questions in the postgraduate entrance examination, train more ideas for doing questions, and be familiar with the way of doing questions in the postgraduate entrance examination. An important feature of mathematics postgraduate entrance examination questions is their comprehensiveness, wide knowledge and high requirements for a series of knowledge points. Only by training step by step and accumulating experience in solving problems can we have a better chance to find a breakthrough in the exam.
