In calculus, a branch of mathematics, the third derivative is the rate at which the second derivative, or the rate of change of the rate of change, is changing, used to define aberrancy. The third derivative of a function ''y=f(x)'' can be denoted by : Other notations can be used, but the above are the most common. ==Mathematical definitions== Let . Then , and . Therefore, the third derivative of ''f''(''x'') is, in this case, : or, using Leibniz notation, : Now for a more general definition. Let be any function of ''x''. Then the third derivative of is given by the following: : The third derivative is the rate at which the second derivative ('' 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「Third derivative」の詳細全文を読む スポンサード リンク
