Ranked first in the postgraduate entrance examination scope: advanced mathematics, linear algebra, probability theory, mathematical statistics.
1. Understand the concept of function and master the expression of function, and you will establish the functional relationship of application problems. The solutions in the postgraduate entrance examination paper are graded according to the steps. In the postgraduate examination paper, 80% of the questions are mainly exams, so most candidates will do the questions with ideas, but the final answer is wrong because of calculation errors.
2. Linear algebra is the core of pure mathematics and applied mathematics, and its meaning expands with the development of mathematics. To understand the essence of space and mapping, space is the conceptual cornerstone of the whole linear algebra. We need to know the essence of mapping and transformation in space in detail, and learn the soul function of matrix in it.
3. Probability theory is a branch of mathematics that studies the quantitative laws of random phenomena, and it is a science that studies the possibility of things happening. The key points are: the distribution and distribution law of multidimensional random variables; Judgment of independence of random variable, distribution of random variable function, convolution formula. Calculation and properties of expectation and variance of random variables: covariance and correlation coefficient formulas.
