无穷小量 Infinitesimal

（重定向自Infinitesimally）

无穷小量是数学分析中的一个概念，用以严格地定义诸如「最终会消失的量」、「绝对值比任何正数都要小的量」等非正式描述。在经典的微积分或数学分析中，无穷小量通常它以函数、串行等形式出现，例如，一个串行 $a=(a_n)_{n\in \mathbb{N}}$ 若满足如下性质：

在 $\displaystyle k>N$ 时必定成立；或用极限符号把上述性质简记为

则串行 $a$ 被称为 $n\to \infty$ 时的无穷小量。

The insight with exploiting infinitesimals was that entities could still retain certain specific properties, such as angle or slope, even though these entities were quantitatively small. The word infinitesimal comes from a 17th-century Modern Latin coinage infinitesimus, which originally referred to the "infinite-th" item in a sequence. It was originally introduced around 1670 by either Nicolaus Mercator or Gottfried Wilhelm Leibniz. Infinitesimals are a basic ingredient in the procedures of infinitesimal calculus as developed by Leibniz, including the law of continuity and the transcendental law of homogeneity. In common speech, an infinitesimal object is an object that is smaller than any feasible measurement, but not zero in size—or, so small that it cannot be distinguished from zero by any available means. Hence, when used as an adjective, "infinitesimal" means "extremely small". To give it a meaning, it usually must be compared to another infinitesimal object in the same context (as in a derivative). Infinitely many infinitesimals are summed to produce an integral.
