1, Linear Algebra: Linear Algebra was examined in Mathematics I and II, accounting for 22%, and it was the best subject with the least difference in content. For many years, the linear generation part of the postgraduate entrance examination questions is exactly the same. The only difference is that there is more knowledge of vector space in the outline of number one.

2. Probability theory and mathematical statistics: mathematics does not investigate, mathematics investigates.

3, high number: both mathematics and mathematics have been investigated, with the largest proportion. The proportion of test paper No.1 is 56%, and that of test paper No.2 is 78%. The scope of the first-hand inspection is the widest; Digital binary vector algebra and spatial analytic geometry, triple integral, curve integral, surface integral, infinite series; Science and engineering (one of the best) with different emphasis should take the physical application of calculus, while economics (one of the best) should change the corresponding content to economic application, and one of the best emphasizes surface integral.
