This is a polynomial p of degree 3 which interpolates a given function f at the points x(-1), x(0), x(1), and x(2), and is given by p(x) = sum from i = -1 to i = 2 of li(x)*f(xi), where li, i = -1,0,1,2, which are called the fundamental polynomials, are given by li(x) = product from k = -1 to k = 2 for k != i of (x - xk)/(xi - xk). li(-1) = (x - 0)/(-1 - 0) * (x - 1)/(-1 - 1) * (x - 2)/(-1 - 2) = (x * (1-x) * (x-2))/6 li(0) = (x - -1)/(0 - -1) * (x - 1)/(0 - 1) * (x - 2)/(0 - 2) = ((x+1) * (x-1) * (x-2))*0.5 li(1) = (x - -1)/(1 - -1) * (x - 0)/(1 - 0) * (x - 2)/(1 - 2) = (x * (x+1) * (2-x))*0.5 li(2) = (x - -1)/(2 - -1) * (x - 0)/(2 - 0) * (x - 1)/(2 - 1) = (x * (x+1) * (x-1))/6
