1, calculus part: differential and integral of unary function; First-order partial derivative of multivariate function; Monotonicity and extremum of functions.

2. Linear algebra: linear equation; The linear correlation of vectors has nothing to do with linearity; Basic operations of matrices.

3. Probability theory: distribution and distribution function; Common distribution; Expectation and variance.

The second is the interpretation of the outline of previous years.

The examination syllabus is relatively short, which only gives the general scope of the examination, but does not completely limit the examination content. There will be some test sites in the whole logic system that are not pointed out in the outline, such as function, limit and continuity. Determinant; Linear expressions of vectors, etc. This requires candidates not to stick to the exam outline when reviewing, but to establish a clear and complete knowledge system and understand the inherent requirements of the exam outline.
