微分无穷小量的几点注记
Notes of Differential Infinitesimal
摘要: 对比了牛顿和莱布尼兹的“以直代曲”的微分思想,本文从不同角度阐释微分求导法在求导过程中的应用,说明其在求导过程中能做到化繁为易。进而,从微分概念的角度阐述高阶微分一般不再具有形式的不变性。
Abstract: In this paper, we compare Newton and Leibniz differential thinking of “replacing curve with straight lines”, describe the application of differential differentiation method in the process of differentiation from different perspectives to illustrate how differential differentiation can simplify the process. Furthermore, from the perspective of the concept of differentiation we explain that higher-order differentials generally no longer have form invariance.
