] gives a polynomial in the variable var which provides an exact fit to a list of data.
The data can have the forms
, ... or
, ... , where in the second case, the are taken to have values 1, 2, ... .
The can be replaced by
, ... , specifying derivatives at the points .
With a list of data of length , InterpolatingPolynomial gives a polynomial of degree .
4, 5, 8
InterpolatingPolynomial gives the interpolating polynomial in Newton form, suitable for numerical evaluation.
See the Mathematica book: Section 3.3.4, Section 3.8.1.

This constructs a polynomial with the values , , , at the points , , , .
This gives a polynomial whose graph passes through the three points given in the list.
