Development of calculus principle
Since the establishment of calculus system for hundreds of years, great achievements have been made in the application of methods. However, there are many imperfections and inaccuracies in the current calculus principle.
1, the current calculus principle cannot be justified in structure;
2. There are many subtle problems;
3. There are many logical errors in the principle of calculus.
Therefore, it is an insurmountable step in the development of mathematics to correct the mistakes of the current calculus principle, establish a new mathematical model and rebuild the new calculus principle that meets the requirements of mathematical development.
