FunctionApproximations`
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 and Options
- To use Derivatives, 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 Derivatives is useful when the Wolfram Language is unable to compute derivatives analytically, or when evaluating the function and its derivatives is computationally expensive, yet involves a significant amount of redundancy.
