What are the three intervals of 2022 postgraduate mathematics?
① Integration (function, limit, continuity, one-variable function calculus, multivariate function calculus, infinite series, ordinary differential equation, difference equation).

② Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form).

③ Probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, joint probability distribution of random variables, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing).

In 2009 10, 1 1, 12, 13, the test items were almost the same, and none of the words changed. In other words, since 2009, great changes have taken place in the mathematics syllabus for postgraduate entrance examination. After the old Math III and Math IV merged into Math III, the math syllabus for the postgraduate entrance examination has been relatively stable in recent years, and the math syllabus for the postgraduate entrance examination has been exactly the same in the past five years.

Test question structure:

First, the examination form

1, full marks in the test paper, and the test time.

The full mark of the test paper is 150, and the test time is 180 minutes.

Step 2 Answer method

The answer methods are closed book and written test.

Second, the content structure of the test paper

Calculus 60%

Linear algebra 20%

Probability theory and mathematical statistics 20%

Third, the question structure of the test paper

10 multiple-choice questions, with 5 points for each question and ***50 points.

Fill in the blanks with 6 small questions, with 5 points for each question and * * 30 points.

Answer (including proof questions) 6 small questions, ***70 points.
