This is normal, and the arbitrary function all can approach with dividing section multinomials because can know from infinitesimal calculus.───这是正常的，因为从微积分可以知道，任一函数都可以用分段多项式来逼近。

if these increases of income or utility are reduced to being infinitesimal, one can use both the symbolism and the powerful manipulations of the differential calculus.───如果这些收入或效用的增加可以化为无穷小，那我们既能使用符号表示，也能利用微分学强大的操作了。

II Limit --- Reasonability of Infinitesimal Calculus.

Mathematical Background: Foundations of Infinitesimal Calculus Second Edition, written by K. D.

The inequality is used widely in functional analysis, matrix theory, it is proved again from infinitesimal calculus.

He invented infinitesimal calculus independently of Newton, and his notation is the one in general use since then.

This is normal, and the arbitrary function all can approach with dividing section multinomials because can know from infinitesimal calculus.
