# scipy.interpolate.BPoly.antiderivative

BPoly.antiderivative(nu=1)

  Construct a new piecewise polynomial representing the antiderivative.

  Parameters
    nu int, optional

      Order of antiderivative to evaluate. Default is 1, i.e., compute the first integral. If negative, the derivative is returned.

  Returns
    bp BPoly

      Piecewise polynomial of order k + nu representing the antiderivative of this polynomial.

  Notes

  If antiderivative is computed and `self.extrapolate='periodic'`, it will be set to False for the returned instance. This is done because the antiderivative is no longer periodic and its correct evaluation outside of the initially given x interval is difficult.
