Mathematical analysis, also known as advanced calculus, is the oldest and most basic branch of analysis. Generally, the general theory of calculus and infinite series is the main content, including its theoretical basis (basic theory of real number, function and limit). It is also a basic course for college mathematics majors. The branch of analysis in mathematics is a branch of mathematics that specializes in studying real numbers and complex numbers and their functions. Calculus is a general term for differential calculus and integral calculus, which is abbreviated as calculation in English, because early calculus was mainly used for calculation problems in astronomy, mechanics and geometry. Later, people also called calculus analysis, or infinitesimal analysis, especially the knowledge of using extreme processes such as infinitesimal or infinity to analyze and deal with calculation problems. Good textbooks in China include A Course of Mathematical Analysis by Shi Jihuai of China University of Science and Technology, A New Lecture on Mathematical Analysis by Peking University, Mathematical Analysis by Nandaqiang, Mathematical Analysis by Zhou Minqiang and Fang of Peking University, and Mathematical Analysis by Ouyang Guangzhong of Fudan University and Chen Jixiu of China. The specific postgraduate entrance examination, because this subject belongs to the professional course of independent proposition, is not within the scope of the public course of national unified proposition, and there may be more versions. It's best to check the enrollment catalogue of the school in recent years, and generally give a bibliography. I hope I can help you.
