Chen Wendeng's Review Guide is well written in the part of advanced mathematics, but the parts of linear algebra and probability theory are rather general, so people who buy this book are mainly directed at advanced mathematics in Chen Wendeng. Generally speaking, it is necessary to supplement the lecture notes on line generation and probability. Many of the above questions are more challenging, and there are corresponding exercises behind them.
This book has clear chapters and detailed contents, and the steps of solving problems are very clear. It is important to attach relevant problem-solving skills. Chen Wendeng has compiled three books, and you can see an interview with Chen Wendeng on the forum. As far as the average person is concerned, you should watch it at least three times, especially in some places where you feel that you are not learning well, especially you need to study and practice repeatedly.
Inventory a postgraduate content:
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, eigenvalues and eigenvectors 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, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing.
It is necessary to thoroughly understand the basic concepts, methods and theorems in combination with undergraduate textbooks and previous years' outlines. Mathematics is a highly deductive subject. Only by deeply understanding the basic concepts and remembering the basic theorems and formulas can we find the breakthrough and breakthrough point of solving problems.
