Newton’s divided difference interpolation formula is used when the values of the independent variable are
Not equally spaced
Newton’s divided difference interpolation formula is a interpolation technique used when the interval difference is not same for all sequence of values. Divided differences are symmetric with respect to the arguments i.e independent of the order of arguments.

Lagrangens interpolation

If y(x) is approximated by a polynomial Pn(x) of degree n then the error is given by
ε(x)=y(x)+Pn(x)
ε(x)=y(x)−Pn(x)
ε(x)=y(x)×Pn(x)
ε(x)=y(x)÷Pn(x)
