massive
Limit, Continuity, Integral: We need to fully understand and master some definitions, and train and use the questions flexibly through the definitions.
One-dimensional and multivariate function calculus: This aspect needs to summarize and understand a system, because the whole calculus starts from this, and sort out the system.
Infinite series and ordinary differential equations: such as variable upper bound definite integral, variable integral domain double integral, necessary and sufficient conditions of total differential, etc. It's all difficult places to set up, so pay more attention.
Infinite series training
Calculus proof and inequality, sequence limit, etc. The difficulty of number one can also be said to be the most difficult knowledge point in the whole test paper, so there is no need to solve such problems with a must-do mentality.
vector generation
Linear equations: including the solution structure of homogeneous and non-homogeneous linear equations, the solution and proof of basic solution system, etc. Generally speaking, it is not difficult, and it can be made by ordinary methods.
Similarity of matrix: it is often the similarity diagonalization of matrix, which is easy to combine with big questions, with strong knowledge flexibility and high comprehensiveness.

? probability theory
Random variables: Generally speaking, there are many concepts and less calculation, which requires a deep grasp of concepts.
Estimation and test: mainly the principles and methods of maximum likelihood estimation and hypothesis test.
