The difference between mathematics one, two and three for postgraduate entrance examination: there are three kinds of mathematics subjects for postgraduate entrance examination, and the biggest difference lies in the requirements for knowledge: mathematics one is the most extensive, mathematics three times, and mathematics two is the lowest. So students who are going to count to three should start reviewing as soon as possible.

1. No.1 is mainly science and some engineering. The content of the exam is two volumes of senior high school mathematics (some of them are not tested, but not many, and the outline changes every year). The content is complex, the knowledge is wide and the difficulty is great. In addition, it also involves the introduction of the generation of poles and lines.

2. The number two is mainly aimed at engineering students. Needless to say, the content of line generation is similar to that of number one, and the high number is mainly in the first volume, and the second volume is mainly double limit, double integral and differential equation. The second volume is the least knowledge but the most difficult in the postgraduate entrance examination mathematics, without taking any other tests.

3. Mathematics III includes: Mathematics III is usually called economic mathematics, including line generation, probability and high number. Applicable disciplines are: two disciplines, the first-class discipline of agriculture, forestry and economic management of management, who has higher requirements for mathematics; Two disciplines, the first-class discipline of applied economics in economics, statistics and quantitative economics; Enterprise management, technical economy and management science are two disciplines in the first-level discipline of business administration.
