Introduction to advanced mathematics

Elementary mathematics studies constants and advanced mathematics studies variables.

Advanced mathematics (also known as calculus) is an important basic subject in science and engineering colleges. As a science, advanced mathematics has its inherent characteristics, namely, high abstraction, strict logic and wide application. Abstract is the most basic and remarkable feature of mathematics-high abstraction and unity, which can profoundly reveal its essential laws and make it more widely used. Strict logic refers to the induction and arrangement of mathematical theories. Whether it is concept and expression, judgment and reasoning, we should use logical rules and follow the laws of thinking. Therefore, mathematics is also a way of thinking, and the process of learning mathematics is the process of thinking training. The progress of human society is inseparable from the wide application of mathematics. Especially in modern times, the appearance and popularization of electronic computers have broadened the application field of mathematics, and modern mathematics is becoming a powerful driving force for the development of science and technology. At the same time, it penetrates into the field of social science extensively and deeply. Therefore, it is very important for us to learn advanced mathematics well. However, many students are confused about how to learn this course well. To learn advanced mathematics well, we must at least do the following four things:

First, understand the concept. There are many concepts in mathematics. Concepts reflect the essence of things. Only by figuring out how it is defined and what its nature is can we really understand a concept.

Secondly, master the theorem. Theorem is a correct proposition, which is divided into two parts: condition and conclusion. In addition to mastering its conditions and conclusions, we should also understand its scope of application and be targeted.

Third, do appropriate exercises on the basis of understanding the examples. In particular, learners need to be reminded that the examples in the textbook are very typical, which is helpful to understand concepts and master theorems. Pay attention to the characteristics and solutions of different examples. Do appropriate exercises on the basis of understanding the examples. Good at summing up problems-not only methods, but also mistakes. After doing this, you will gain something and be able to draw inferences from others.

Fourth, clear the context. We should have an overall grasp of the knowledge we have learned and sum up the knowledge system in time, which will not only deepen our understanding of knowledge, but also contribute to further study.

Advanced mathematics includes calculus and three-dimensional analytic geometry, series and ordinary differential equations, among which calculus is the most systematic and widely used in other courses. The theory of calculus was completed by Newton and Leibniz. (Of course, calculus was applied before them, but it was not systematic enough. ) The basic concepts of calculus and extreme calculus are difficult to understand.
