Cubic-spline interpolation
Webfind the corresponding cubic spline and evaluate it at x =3. Is the result more accurate than the one of the natural cubic spline interpolation? Note: No programming is necessary, but a calculator might help. Solution: Let the cubic spline in the interval from x =2 to x =4 be the polynomial S1(x) =0.5+b1 (x −2)+c1 (x −2)2 +d1 (x −2)3
