# scipy.misc.derivative

`scipy.misc.``derivative`(func, x0, dx=1.0, n=1, args=(), order=3)

  Find the n-th derivative of a function at point x0.

  Given a function, use a central difference formula with spacing dx to compute the n-th derivative at x0.

  Parameters : | func : function Input function. x0 : float The point at which nth derivative is found. dx : int, optional Spacing. n : int, optional Order of the derivative. Default is 1. args : tuple, optional Arguments order : int, optional Number of points to use, must be odd.

  Notes

  Decreasing the step size too small can result in round-off error.

  Examples

      >>> def x2(x):
      ...     return x*x
      ...
      >>> derivative(x2, 2)
      4.0
