Solution: Let x 0 = 1;x 1 = 0;x 2 = 1. The Lagrange Form suggests that we write it like P(x) = L 0(x)f(x 0) + L 1(x)f(x 1) + L 2(x)f(x 2) where we need to nd polynomials L i(x) of degree 2 (or less) such that L i(x j) = 1 i= j 0 i6=j Or to be more explicit in this simple case:
Solution: Let x 0 = 1;x 1 = 0;x 2 = 1. The Lagrange Form suggests that we write it like P(x) = L 0(x)f(x 0) + L 1(x)f(x 1) + L 2(x)f(x 2) where we need to nd polynomials L i(x) of degree 2 (or less) such that
