The entrance examination of economics is a business examination subject of the master of economics examination, including mathematics, logic and writing. Hunting and Postgraduate Entrance Examination The scope and knowledge points of the "396 Economics Joint Entrance Examination" compiled by Bian Xiao hope to provide reference for students who take the postgraduate entrance examination.

Examination scope:

The range of mathematical knowledge involved in the test questions is:

1. Calculus section

Differential and integral of unary function;

First-order partial derivative of multivariate function;

Monotonicity and extremum of functions.

2. Linear Algebra Part

Linear equation;

The linear correlation of vectors has nothing to do with linearity;

Basic operations of matrices.

3. Probability theory part

The concepts of distribution and distribution function;

Common distribution (normal distribution, Poisson distribution, binomial distribution, exponential distribution, geometric distribution);

Expected value, variance and operational attributes.

2. Test specific knowledge points:

First of all, calculus

1. functional domain

2. Calculation limit (equivalent infinitesimal substitution+Robida rule+four algorithms+Taylor)

3. Find the derivative (first derivative+higher derivative)

4. Judge monotonicity+concavity

5. Find the extreme value of the function

6. Economic application of derivatives

7. Calculate definite integral+indefinite integral

8. Geometric meaning of definite integral

9. The basic properties of definite integral

10. Find the derivative of the implicit function determined by the equation.

Second, linear algebra.

1 1. Calculate the determinant

12. Find the adjoint matrix+inverse matrix of a square matrix

13. Basic operational properties of determinant+matrix

14. Solutions of homogeneous+nonhomogeneous linear equations

15. Properties of Solutions of Homogeneous+Inhomogeneous Linear Equations

16. Maximal linear independent group of vector group+rank

17. judging the linear correlation+linear independence of vector groups

Third, probability theory.

18. Given the probability density function (distribution function) of r.v, find the unknown parameters and probability.

19. Given the distribution of R.V., find the expectation and variance of another R.V..

20. Given the probability of r.v in a certain interval, find the probability of r.v in another interval.

2 1. Judge whether it is a distribution function (canonical, nonnegative, right continuous).
