L'Hôpital's rule

IPA（発音記号）

/ˌloʊpiːˈtɑːlz ˈɹuːl/

固有名詞

(mathematics) The rule that the limit of the ratio of two functions equals the limit of the ratio of their derivatives, usable when the former limit is indeterminate and the latter limit exists.

日本語の意味

（数学）二つの関数の比の極限が、その導関数の比の極限に等しいとする規則。すなわち、元の関数の極限が不定形の場合、導関数を用いて極限を求める手法。

Because both the numerator and denominator approach zero, you can apply L'Hôpital's rule to evaluate the limit.

分子と分母がともに0に近づくため、その極限を評価するにはロピタルの定理を適用できます。
