Intermediate Value Theorem

“Intermediate Value Theorem” 是一个数学术语，通常被简写为 IVT。它是微积分中的一个重要定理，主要用于分析函数的性质。接下来将对该词进行详细分析。

词义分析

该词组由三个部分组成：

• intermediate（中间的，过渡的）
• value（值，数值）
• theorem（定理，理论）

近义词与反义词

在数学中，相关的概念可能包括：

• 近义词：continuity theorem（连续性定理）
• 反义词：discontinuity（不连续性）

用法

Intermediate Value Theorem 主要用于函数分析中，尤其是在证明某个函数在某个区间内存在根或值的情况时。

例句

• The Intermediate Value Theorem states that if a function is continuous on an interval, then it takes every value between its endpoints.
