A cubic spline can represent this function exactly. To achieve that we need to specify values and first derivatives at endpoints of the interval. Note that y’ = 3 * x**2 and thus y’ (0) = 0 and y’ (1) = 3. >>> cs = CubicSpline( [0, 1], [0, 1], bc_type=( (1, 0), (1, 3))) >>> x = np.linspace(0, 1) >>> np.allclose(x**3, cs(x)) True Attributes: Web22 Sep 2015 · Use the above values and five-digit rounding to construct a cubic spline Q with boundary conditions. Q ′ (x0) = f ′ (x0) and Q ′ (xn) = f ′ (xn) which force the slopes of the spline to assume certain values (in our case the values f ′ (x0) and f ′ (xn) respectively) at the two boundaries. Use this spline to approximate sin0.33.
