WebIn this worksheet, we will practice using the Lagrange error bound (Taylor’s theorem with remainder) to find the maximum error when using Taylor polynomial … WebNov 24, 2024 · It can easily be shown that the n + 1 'th derivative of Ln(x) is: n! xn + 1 If x ≥ 1, then the biggest value this takes is when x = 1, so simply n!. Substituting into the lagrange error bound we get: lim n → ∞n! ∗ (x − 1)n n! = lim n → ∞(x − 1)n This does not reach 0 if x − 1 ≥ 1, so x must be less than 2.

Lagrange Error Bound - Medium

WebYou want to estimate the error in the linear approximation 1 − x. Then f ″ ( c) 2 ≈ 1 − 3 c + 6 c 2 If 1 / 2 < x < 1, the maximum of this is not at c = 0 but rather at c = x. The Lagrange bound is then approximately ( 1 − 3 x + 6 x 2) x 2, which is different from the alternating series bound of x 2.
