WebThe Lagrange form of the interpolating polynomial is where (13) are cardinal polynomialsthat satisfy (14) The Lagrange form gives an error term of the form (15) where (16) The underlying function f(x) is often unknown and the number is only known in simple examples. Thus, is the only part of the error term which can be controlled.

Lagrange basis interpolation considers all potential curves and then selects the one that produces the best fit for the data set.
