  • Abstract: the function of learning is the foundation of all modern scientific activities is the most important content, since ancient times, people learn the research above, there is no stop in function, calculus of functions play an important role in many fields, in this paper, I will start from multivariate function extreme value, discuss some extremum method, and discuss the relationship between he and differential, and establish proper geometric model discuss the multivariate function integral calculus, then the function of many variables calculus study on geometric direction are discussed, at last I also on the direction of the series to the discussion of function of many variables calculus study, through this article, I want people to use another way to look at calculus, try to introduce some new discoveries of modern physics in the study of the basic subject of mathematics.
