WebDec 30, 2024 · Lagrange polynomial is another form used for polynomial interpolation. It is called a form because with a given set of distinct points the interpolating polynomial is unique. We can arrive at the same polynomial through different methods. The Lagrange form specifies the interpolation polynomial as: Webi), and we wish to create a simple formula p(x), called an interpolant, that matches our data, and allows us to \predict" yvalues for new xvalues. If there really was a formula f(x) that generated our data, we want to compare f(x) and p(x) and see how well our interpolant approximated the actual formula. The polynomial interpolation problem
