According to relevant regulations, students majoring in economics will take Mathematics III for the postgraduate entrance examination. The exam content of Mathematics III is calculus, linear algebra and probability theory. Mathematics is the basis of economics. In the study of economics, a large amount of mathematical theories and knowledge must be used. Mathematics plays an important role in economic research. It is not only a necessary tool to solve various economic problems, but also greatly promotes the progress and development of economics.

Test content

According to the examination syllabus of Mathematics 3 for the Postgraduate Entrance Examination, the examination question structure of Mathematics 3 is multiple choice questions, fill-in-the-blank questions and answer questions. Among them, the multiple-choice questions include 8 questions, the fill-in-the-blank questions include 6 questions, and the final solution questions include 9 questions. The test time is 180 minutes, and the test paper score is 150 points. In terms of exam content, Mathematics III has three parts, namely calculus, linear algebra and probability theory. Their content proportions are 56%, 22% and 22% respectively.

Differences from Mathematics 1 and 2

First of all, Mathematics 1 and 2 are aimed at candidates majoring in engineering. Among them, Mathematics 1 targets 20 majors such as mechanical engineering and optical engineering, while Mathematics 2 targets 5 majors such as light industry skills and engineering, and agricultural engineering. Therefore, candidates need to decide which mathematics subject to take based on their major. Secondly, Mathematics III has different requirements from Mathematics I and II. Therefore, there will be slight differences in difficulty. Generally speaking, Mathematics 1 is the most difficult, followed by Mathematics 3. However, according to the principle of question setting, in fact, the difficulty of postgraduate entrance examination mathematics is set at above medium, and the passing rate is only set at about 35%.

Application of Mathematics in Economics

In practical economic work, economics mostly uses mathematical models to verify the relationship between various economic variables. Economic variables such as insurance, stocks, and interest rates are predicted through mathematical models, so many graduates of this major enter various financial institutions (such as futures markets and foreign exchange markets) to do technical analysis assignments. Therefore, the application of mathematical foundations is quite important for economics. Candidates should take this subject seriously.
