# scipy.interpolate.PPoly.antiderivative

`PPoly.``antiderivative`(nu=1)

  Construct a new piecewise polynomial representing the antiderivative.

  Antiderivativative is also the indefinite integral of the function, and derivative is its inverse operation.

  Parameters: | nu : int, optional Order of antiderivative to evaluate. (Default: 1) If negative, the derivative is returned.
  Returns: | pp : PPoly Piecewise polynomial of order k2 = k + n representing the antiderivative of this polynomial.

  Notes

  The antiderivative returned by this function is continuous and continuously differentiable to order n-1, up to floating point rounding error.
