[an error occurred while processing this directive] ND

  • ND[ f , x , ] gives a numerical approximation to evaluated at the point .
  • ND[ f , { x , n }, ] gives the derivative.
  • You should realize that with sufficiently pathological examples, the algorithms used for ND can give wrong answers.
  • See also: D , SolveODE .
