Multiple choice questions and fill-in-the-blank questions mainly examine basic concepts, basic formulas, basic theorems and basic operations. Answers include calculation questions and proof questions. The content of the exam is more comprehensive.
Usually a question examines multiple knowledge points. Judging from the characteristics of test papers in recent years, the test questions are average and not too difficult. We'd better do it in the order of the questions. This can stabilize the mood, quickly enter the state, and it is not easy to miss the problem.
Matters needing attention in postgraduate mathematics
Key steps must be recalculated in time. If the previous step is not carefully calculated, even if it can be done later, it will be done in vain, and the whole question is still zero. For example, study the properties of functions, don't make mistakes, simplify the lines of solving equations, don't make mistakes in the quadratic matrix, don't make mistakes in the calculation limit of multiple integrals, and do the second question on the basis of the first question to ensure the correctness of the first question.
If you feel that what you have done is wrong, you must immediately check what you have done before to see if there are any miscalculations or improper use of methods, such as the choice of coordinate system and integration order of double integration, and whether symmetry can be used.
The process can be written separately as far as possible. For example, after the double integral is split into two parts, the calculation process of each part is written separately, so if one part is right and the other part is wrong, the right part is still divided, so don't write the equal sign at the end.
