Instead, one can construct the Hermite polynomial using a Newton divided-di erence table, in which each entry corresponding to two identical interpolation points is lled with the value of f0(x) at the common point. Then, the Hermite polynomial can be represented using the Newton divided-di erence formula. Di erentiation
