In mathematics, the approximate limit is a generalization of the ordinary limit for real-valued functions of several real variables. A function ''f'' on has an approximate limit ''y'' at a point ''x'' if there exists a set ''F'' that has density 1 at the point such that if ''x''''n'' is a sequence in ''F'' that converges towards ''x'' then ''f''(''x''''n'') converges towards ''y''. ==Properties== The approximate limit of a function, if it exists, is unique. If ''f'' has an ordinary limit at ''x'' then it also has an approximate limit with the same value. We denote the approximate limit of ''f'' at ''x''0 by Many of the properties of the ordinary limit are also true for the approximate limit. In particular, if ''a'' is a scalar and ''f'' and ''g'' are functions, the following equations are true if values on the right-hand side are well-defined (that is the approximate limits exist and in the last equation the approximate limit of ''g'' is non-zero.) : 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「Approximate limit」の詳細全文を読む スポンサード リンク
