Judging from the content of the exam: Math 1 and Math 3 are all three subjects, and Math 2 does not take probability theory and mathematical statistics.

The content of the second exam of mathematics for postgraduate entrance examination:

1, advanced mathematics (function, limit, continuity).

Concept and representation of function: boundedness, monotonicity, periodicity and parity of function, composite function, inverse function, piecewise function and implicit function, properties and graphs of basic elementary function, elementary function.

The establishment of function relationship, the definition and properties of sequence limit and function limit, the left and right limits of function, the concepts and relationships between infinitesimal and infinitesimal, the properties and comparison of infinitesimal, and the four operations of limit.

There are two criteria for the existence of limit: monotone bounded criterion and pinch criterion; two important limitations: the concept of function continuity; Types of discontinuity points of elementary functions; Properties of continuous functions on closed intervals.

2. Linear algebra.

Determinants, matrices, vectors, linear equations, eigenvalues and eigenvectors of matrices.
