Finite difference coefficient : ウィキペディア英語版 | Finite difference coefficient In mathematics, to approximate a derivative to an arbitrary order of accuracy, it is possible to use the finite difference. A finite difference can be central, forward or backward. ==Central finite difference==
This table contains the coefficients of the central differences, for several orders of accuracy:〔.〕 For example, the third derivative with a second-order accuracy is : where represents a uniform grid spacing between each finite difference interval.
