In mathematics, the Legendre forms of elliptic integrals are a canonical set of three elliptic integrals to which all others may be reduced. Legendre chose the name ''elliptic integrals'' because〔 〕 the second kind gives the arc length of an ellipse of unit semi-minor axis and eccentricity (the ellipse being defined parametrically by , ). In modern times the Legendre forms have largely been supplanted by an alternative canonical set, the Carlson symmetric forms. A more detailed treatment of the Legendre forms is given in the main article on elliptic integrals. == Definition == The incomplete elliptic integral of the first kind is defined as, : and the third kind as : of Numerical Recipes.〔 The respective complete elliptic integrals are obtained by setting the amplitude, , the upper limit of the integrals, to . The Legendre form of an elliptic curve is given by : 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「Legendre form」の詳細全文を読む スポンサード リンク
