微分学 [

[数] differential calculus
- 积分上限函数是一元函数微分学的基本概念。
Integral upper limit function is a basic concept in function differential calculus. - 证明了高价无穷小可以分解成一种适用的形式,从而使多元函数微分学中的某些定理的条件减弱。
By applying this form, the conditions of some theorems involved in differential calculus of multivariate are hence weakened. - 因为,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。
For 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.
