First of all, the first multiple-choice question, at present, the answers of various institutions about choosing A or D are different; The answer to the third cross-examination version is not directly done, and the seventh and eighth questions are also difficult. The last test of unbiased estimation of fill-in-the-blank questions, this knowledge point is not in the outline of 20 13, and major universities have not reminded candidates to pay attention to this content; For the quadratic standard fill-in-the-blank problem, the method of finding eigenvalue with characteristic determinant is completely ineffective and must be solved by matching method. If you don't master the matching method, the problem will hang up.

The limit of the first question of the big question is disgusting, which requires a very good understanding of the equivalent infinitesimal and Robida. Many candidates finally answered 0, which is wrong.

Many candidates can't write big double integral if they only do sin/sincos. In fact, it involves the content of sum-difference product in elementary mathematics. In addition, 20 14 rarely investigates a big problem and an infinite series of differential equations, and these two big problems are not given for nothing. It is wrong to say that the infinite series s(0)=3, which should be 0. In addition, although the topic of probability in linear algebra is quite satisfactory, there are still gaps and obstacles, which need to be reviewed comprehensively. Linear algebra and advanced mathematics each have a proof problem, which was impossible in previous years, indicating that mathematics III has also begun to emphasize the thinking of logical proof.

Generally speaking, the mathematics of 20 13 is relatively simple, so 20 14 is more difficult. It is normal to estimate that the average score of 20 14 is 5-6 points less than 20 13.
