Sorted by: 2. Presumably, it should be f ∈ C n + 1 [ a, b], i.e. f is n + 1 times continuously differentiable on the closed interval [ a, b]. Then, for any x ∈ [ a, b], you have the formula. f ( x) − P ( x) = f ( n + 1) ( ξ ( x)) ( n + 1)! ( x − x 0) ⋯ ( x − x n), where P is the polynomial of degree n interpolating f in ...

We can then approximate the model using Lagrange Interpolation in the following way: u → ( x, y, z) ≈ ∑ i = 1 n u → i L i ( x, y, z) where L i ( ⋅) represents the i t h Lagrange Polynomial ... WebThe polynomial P(x) given by the above formula is called Lagrange’s interpolating polynomial and the functions L0,L1,L2 are called Lagrange’s interpolating basis functions. Remark Note that deg(P2) ≤ 2 and that Li(xj)=δij = (0 i 6=j 1 i = j δij is called the Kronecker delta function. Example Construct P2 from the data points (0,−1),(1 ... WebThe Lagrange interpolation formula is a way to find a polynomial which takes on certain values at arbitrary points. Specifically, it gives a constructive proof of the theorem below. … churchfields primary school barnsley
