The main contents include: 1, advanced mathematics (function, limit, continuity, calculus of univariate function, vector algebra and spatial analytic geometry, calculus of multivariate function, infinite series, ordinary differential equation).
2. Linear algebra (determinant, matrix, vector, linear equations, eigenvalue and eigenvector of matrix, quadratic form).
3, probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, two-dimensional random variables and their probability distribution. Digital characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation, hypothesis testing).
Precautions:
First of all, teachers must be considered when learning mathematics. The difference between the military champion and the postgraduate champion is that the postgraduate entrance examination is deeper and more detailed, and the content is similar. At this time, the role of teachers is particularly important. A teacher can save you a lot of detours. Considering the teacher is the way he does the problem, not whether you like the teacher or not.
Secondly, I suggest you sign up for classes or take online classes. One of the best has a lot of content. If there is no systematic study, there is definitely a problem, but you must pay attention to the teacher when you report to class!
