翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Directed infinity ： ウィキペディア英語版 Directed infinity A directed infinity is a type of infinity in the complex plane that has a defined angle ''θ'' but an infinite absolute value ''r''. For example, the limit of 1/''x'' where ''x'' is a positive number approaching zero is a directed infinity with angle 0; however, 1/0 is not a directed infinity, but a complex infinity. Some rules for manipulation of directed infinities are: *$w\backslash infty\; +\; z\backslash infty\; =\; (w+z)\backslash infty$ *$z\backslash infty\; =\; \backslash frac\backslash infty.$ *$0\backslash infty\backslash text\backslash frac$ * *$w\backslash infty\; z\backslash infty\; =\; (w\; z)\backslash infty$ == See also == *Point at infinity 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Directed infinity」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
