FUNCTION APPROXIMATIONS PACKAGE SYMBOL

Derivatives

is an option to MiniMaxApproximation and GeneralMiniMaxApproximation that specifies an expression that evaluates to a list containing the function and its first two derivatives.

Details Details

To use , you first need to load the Function Approximations Package using Needs["FunctionApproximations`"].
With the default setting Derivatives->Automatic, MiniMaxApproximation and GeneralMiniMaxApproximation compute derivatives using D.
The option is useful when Mathematica is unable to compute derivatives analytically, or when evaluating the function and its derivatives is computationally expensive, yet involves a significant amount of redundancy.
