It is generated by two circles of radius ''b'' with centers distance 2''a'' apart (taken to be at (±''a'', 0). A line segment of length 2''c'' attaches to a point on each of the circles, and the midpoint of the line segment traces out the Watt curve as the circles rotate. It arose in connection with James Watt's pioneering work on the steam engine. The equation of the curve can be given in polar coordinates as :$r^2=b^2-\backslash left()^2.$ ==Derivation== 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「Watt's curve」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.
