1, definition
Calculus is a branch of mathematics, which studies the differential and integral of functions and related concepts and applications in higher mathematics. It is the basic subject of mathematics. The content mainly includes limit, differential calculus, integral calculus and its application. Differential calculus, including the calculation of derivatives, is a set of theories about the rate of change. It makes the function, velocity, acceleration and curve slope can be discussed with a set of universal symbols. Integral calculus, including the calculation of integral, provides a set of general methods for defining and calculating area and volume.
2, the basic content
The basic concepts and contents of calculus include differential calculus and integral calculus.
The main contents of differential calculus include: limit theory, derivative, differential and so on.
The main contents of integral include definite integral, indefinite integral and so on.
3. Relevant assessment
Von Neumann said: Calculus is the first achievement of modern mathematics, and its importance cannot be overestimated. In my opinion, calculus shows the beginning of modern mathematics more clearly than anything else; Moreover, as its logical development, mathematical analysis system still constitutes the greatest technological progress in precision thinking.
Atia said: People are calling for lowering the position of calculus in science education and replacing it with discrete mathematics which is more closely related to computer research. Many important results of discrete phenomena are best proved by calculus. Until now, the infinite central position of calculus analysis is still indisputable.
