However, there is another level of postgraduate entrance examination, that is, mathematics. Fortunately, it is not that all majors have to take the math test, and math is also divided into math one, two and three. Therefore, if you want to have a greater chance of landing in the postgraduate entrance examination, you should also consider taking one, two or three math exams when choosing a major in colleges and universities.

What's the difference between one, two, three in postgraduate mathematics?

Mathematics one

Examination subjects and content structure: advanced mathematics 56%, linear algebra 22%, probability theory and mathematical statistics 22%.

Mathematics ii

Examination subjects and content structure: advanced mathematics 78%, linear algebra 22%.

Mathematics three

Examination subjects and content structure: calculus 56%, linear algebra 22%, probability theory and mathematical statistics 22%.

What is the focus of these exams?

Advanced mathematics:

Include limit, differential calculus of univariate function, integral calculus of univariate function, differential calculus of multivariate function, double integral and differential equation.

Take all the limit parts.

In differential calculus of univariate function, physical application, curvature and some related change rates are the test sites of number one and number two, in which number two mainly examines frequency.

In differential calculus of multivariate functions: Except Taylor formula of multivariate functions, others are the best public test sites.

In the double integral: except for the cylinder volume, total mass, centroid coordinates and unique number of moment of inertia, others are the best public test sites.

In the breeze equation, there are many unique equations. Solving equations, such as arc length, lateral area, curvature, centroid and some equations established by the rate of change, all belong to the application category.

Unlimited series: This part is exclusive to No.1, and will not be tested on No.2..

linear algebra

Including determinant, matrix, linear equations, vector group, similarity theory and quadratic form.

Although this book is one of the three public course textbooks, there are not as many knowledge points as advanced mathematics.

Determinant, matrix, linear equations and similarity theory are the best commonly used test sites, and there is no difference.

Vector group: there is one knowledge point exclusive to number one, which is vector space.

Quadratic type: there is a little knowledge of exclusive number one, which is called geometric application. In the orthogonal transformation method, the rest are public test sites.
