What is Mathematics 1 Mathematics 3 and Mathematics 4 in the postgraduate entrance examination

Mathematics 1, Mathematics 2, Mathematics 3, and Mathematics 4 refer to the four categories of Mathematics for the Postgraduate Entrance Examination.

According to the different requirements of various disciplines and majors for the mathematical knowledge and ability that master's students should have, the mathematics test papers of the master's entrance examination are divided into three types: among them, mathematics is for engineering.

1. Mathematics II.

For economics and management, mathematics III (before 2009, management was mathematics III, economics was mathematics IV, and after 2009, mathematics III and mathematics IV were combined in the syllabus). There are specific regulations on the types of test papers used for different majors.

The content of the Mathematics III Postgraduate Examination is as follows:

Calculus: Functions, Limits, Continuous, Unary Calculus, Calculus of Multivariate Functions, Infinite Series, Ordinary Differential Equations, and Difference Equations.

Linear algebra: determinants, matrices, vectors, systems of linear equations, eigenvalues and eigenvectors of matrices, quadratic forms.

Probability Theory and Mathematical Statistics: Random Events and Probability, Random Variables and Their Probability Distributions, Joint Probability Distributions of Random Variables, Numerical Characteristics of Random Variables, Law of Large Numbers and the Central Limit Theorem, Basic Concepts of Mathematical Statistics, Parameter Estimation, Hypothesis Testing.

You need to take the major of Mathematics III

All the second-level disciplines and majors in the first-level discipline of theoretical economics in the category of economics.

The second-level disciplines and majors in the first-level disciplines of applied economics in the economic category: statistics, quantitative economics, national economics, regional economics, public finance (including taxation), finance (including insurance), industrial economics, international science, labor economics, and national defense economy.

The second-level disciplines and majors in the first-level disciplines of business administration in the category of management: business management (including financial management, marketing, human resource management), technical economics and management, accounting, and tourism management.

All the second-level disciplines and majors in the first-level discipline of agriculture and forestry economic management in the category of management.

1. The content is different: the content of the Mathematics 1 exam is the most, and the content of the Mathematics 2 exam is the least deleted. Mathematics III is Advanced Mathematics, Linear Algebra, and Probability and Statistics.

2. Students are different: Mathematics is the examination for students who apply for science and engineering, Mathematics is the examination for students who apply for agriculture, and Mathematics is the examination for students who apply for economics.

3. The focus is different: the content of the Mathematics I exam includes advanced mathematics, linear algebra and probability theory and mathematical statistics, the content of the Mathematics II exam only includes advanced mathematics and linear algebra, and the third advanced mathematics part mainly focuses on the examination of calculus, and there is no hypothesis testing and confidence interval in probability statistics.

The content is different, and counting one is more difficult.

Graduate school mathematics is divided into numbers.

1. Number. Second, number three, each range is different, and there is a range of tests in the following **.

1. Different test subjects.

Mathematics I examines subjects such as Advanced Mathematics, Linear Algebra, Probability Theory and Mathematical Statistics.

The proportion of each subject is: Advanced Mathematics 56%, Linear Algebra 22%, Probability Theory and Mathematical Theory 22%.

The examination subjects of Mathematics II for the postgraduate entrance examination are: Advanced Mathematics and Linear Algebra.

In the test questions, the proportion of each subject is: 78% in Advanced Mathematics and 22% in Linear Algebra

The subjects of the three exams in Mathematics for the Postgraduate Entrance Examination are: Calculus, Linear Algebra, Probability Theory and Mathematical Statistics.

2. The content of the test is different.

Number. 1. Number.

The difference between the second and third mathematics in the content of the examination is mainly reflected in the scope of the examination, in which the scope of mathematics I is relatively wide, and the scope of mathematics II is relatively narrow.

Specifically, in higher mathematics, numbers.

1. Number. 2. The main differences between number 3 are: spatial analytic geometry, multivariate function integration (except for double integral), only mathematics 1 is examined; Infinite series, math only.

1. Mathematics III Examination; Physical applications of calculus, mathematics only.

1. Mathematics 2 examination; The economics application of calculus is only examined in mathematics III.

The content and requirements of the test are almost the same as those of the first and third numbers, the difference is that the mathematics one has more content in the vector empty and noisy fights, and this part of the test points is very little involved in the exam and has no substantial impact on the candidates' review.

In Probability Theory and Mathematical Statistics, the scope of the Mathematics 1 exam is slightly larger than that of Mathematics 3, and the test points of the parameter estimation part are mainly added, including the selection criteria of estimators, interval estimation and subsequent hypothesis testing.

The content of the Postgraduate Mathematics III exam is as follows:

Calculus, Linear Algebra, Probability Theory and Mathematical Statistics. The maximum score of the Mathematics 3 paper is 150 points, and the exam time is 180 minutes. The answer method is closed-book and written test.

Calculus accounts for 56% of the content of the test paper; Linear Algebra 22%; Probability Theory and Mathematical Statistics 22%. The question structure of the test limb paper: 8 multiple-choice questions, 4 points for each question, a total of 32 points; Fill-in-the-blank questions: 6 questions, 4 points each, a total of 24 points; Answer 9 questions, a total of 94 points.

The difference between the graduate school entrance examination mathematics one, two, three:

1. Mathematics is divided into three categories, and the biggest difference lies in the requirements of knowledge: mathematics 1 is the broadest, mathematics 3 is second, and mathematics 2 is the lowest. This difference is reflected in the details, which becomes mathematics.

1, 2 and 3 are different in terms of exam content and applicable majors.

2. Postgraduate mathematics is divided into mathematics from the perspective of paper types.

1. Mathematics. 2. Mathematics III; From the perspective of the content of the exam, it covers advanced mathematics, linear algebra, probability theory and mathematical statistics; In terms of the structure of the test paper, there are three types of questions: multiple-choice questions, fill-in-the-blank questions, and answer questions.

3. Among them, the number one and the number three are consistent in the distribution of problem types: -19 belongs to the topic of advanced mathematics -21 belongs to the topic of linear algebra -23 belongs to the topic of probability theory and mathematical statistics; Mathematics 2 is different, -21 is a topic of advanced mathematics, and -23 is a topic of linear algebra.
