# scipy.interpolate.BPoly.derivative

BPoly.derivative(nu=1)

  Construct a new piecewise polynomial representing the derivative.

  Parameters
    nu int, optional

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

  Returns
    bp BPoly

      Piecewise polynomial of order k - nu representing the derivative of this polynomial.
