关于《贝克莱悖论与点态连续性概念及有关问题》的注记
A Note Concerning “On Berkeley’s Paradox,Point-Wise Continuity Concept and Related Questions”
【摘要】 形式悖论"Δx≠0与Δx=0"出现于蕴含点态连续性的导数极限等式,是合理的必然结果.差商函数的连续性延拓有分析意义和几何意义.
【Abstract】 This expository note explains why the formal paradox "Δx≠0 and Δx=0" could be reasonably involved in an analytic equality that relates the derivative f′(x) of a differentiable function y = f(x) with the normalized limit of Δy/Δx as Δx→0±,etc.Also presented is a related geometrical interpretation.
