The emphasis is different: advanced mathematics accounts for 60%, linear algebra accounts for 20%, and probability theory accounts for 20%. Number two: infinite series, line integral, area score, probability statistics number three, number four. It seems that a probability theory is in the majority and a linear algebra is in the majority. /kloc-Respondents 0/5 years ago: Cute little bear-branch Q, level 4, No.2, is actually the most difficult. Respondents: johnnykyun-Q, a first-class science and engineering student, took Math I and II, General Management School took Math III, and Economics took Math IV. This one, two, three and four are not different in difficulty, but in the range of knowledge points. Number one and number three have the largest range. Followed by four. The number two has the smallest range. The scope is large, and there are many things to review, which gives people a relatively difficult feeling. The high number of number one is the most difficult, and the linearity and probability of number three and number four are difficult. Probability one: advanced mathematics has changed from about 60% in 2007 to about 56%, linear algebra from about 20% in 2007 to about 22%, and probability theory and mathematical statistics from about 20%. About 20% of linear algebra became "about 78% of advanced mathematics and about 22% of linear algebra" in 2007. Number three: content ratio: dental calculus increased from about 50% to about 56%; Linear algebra is reduced from about 25% to about 22%; Probability theory and mathematical statistics dropped from about 25% to about 22%. Number four: calculus 50% linear algebra 25% probability theory 25% in 2006; Since 2007, calculus 56% linear algebra 22% probability theory 22% According to the different requirements of engineering, economics, management and other disciplines for majors, the mathematics unified examination papers are divided into Mathematics I, Mathematics II, Mathematics III and Mathematics IV. The enrollment majors applicable to each test paper are as follows: Mathematics is applicable to enrollment majors: 1. Mechanics, mechanical engineering, optical engineering, instrument science and technology, metallurgical engineering, power engineering and engineering thermophysics, electrical engineering, electronic science and technology, information and communication engineering, control science and engineering, computer science and technology, civil engineering, water conservancy engineering, surveying and mapping science and technology, transportation engineering, ship and ocean engineering, aerospace science and technology, armament science and technology, nuclear science and technology, biomedical engineering and other first-class disciplines. 2. Which of the two disciplines, materials science and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, environmental science and engineering, has higher requirements for mathematics? 3. The first-class discipline of management science and engineering in the field of management. Mathematics 2 is applicable to the enrollment major: 1. Textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering, food science and engineering, etc. are all majors and first-class disciplines in two disciplines. 2. two disciplines is a major with low requirements for mathematics in the first-class engineering disciplines, such as materials science and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, and environmental science and engineering. Mathematics III is applicable to the enrollment major: 1. Economics applied economics is a kind of statistics, quantitative economics, two disciplines and majors. 2. Business administration, technical economy and management are two disciplines, and the major is the first-class discipline of business administration.
