Now let ''P''1 and ''P''2 be the two points on ''L'' whose distance from ''K'' is the same as the distance from ''A'' to ''K''. The locus of such points ''P''1 and ''P''2 is then the strophoid of C with respect to the pole ''O'' and fixed point ''A''. Note that ''AP''1 and ''AP''2 are at right angles in this construction. In the special case where ''C'' is a line, ''A'' lies on ''C'', and ''O'' is not on ''C'', then the curve is called an oblique strophoid. If, in addition, ''OA'' is perpendicular to ''C'' then the curve is called a right strophoid, or simply strophoid by some authors. The right strophoid is also called the logocyclic curve or foliate. ==Equations== 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「Strophoid」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.
