The concept of limit in mathematics, for the unknown quantity under investigation, first try to correctly conceive another variable related to its change, and confirm that the trend result of the influence of this variable through the infinite change process is very accurate, which is approximately equal to the unknown quantity sought; The result of the unknown quantity under investigation can be calculated by the limit principle.
Brief introduction to other situations of mathematical limit.
The further development of limit thought is closely related to the establishment of calculus. /kloc-in the 0/6th century, Europe was in the embryonic stage of capitalism and its productive forces developed greatly. There are many problems in production and technology. At first, people could not solve them with elementary mathematics. It is the social background to promote the development of extreme thinking and establish calculus to require mathematics to break through the traditional scope of "only studying constants" and find new tools that can describe and study the process of motion change.
