Second derivative backward difference
WebHigher derivatives Many applications require the second derivative of a function. It’s tempting to use the finite difference of a finite difference. For example, applying (135) twice leads to (136) This is a valid formula, but it uses values at rather than the closer values at . WebBackward differences are useful for approximating the derivatives if the data values are available in the past but not in the future (such as secant methods for root finding and control problems). Given the values f(x -1 ) and f(x 0 ), the backward difference approximates the value f(x 1 ), if it depends on f'(x 0 ).
