Taylor-expand the exact value y(t n+1). 4. Subtract the expanded form of the approximation y n+1 (from step 2) from the expanded form of the exact value y(t n) (from step 3) to get the local truncation error: LTE= y(t

www3.nd.edu › ~zxu2 › acms40390F15Comparing m-step explicit step method vs. (m-1)-step implicit step method . a) both have the same order of local truncation error, ππ(βππ). b) Implicit method usually has greater stability and smaller round-off errors. For example, local truncation error of Adams-Bashforth 3-step explicit method, ππππ+1(β) = 3 8
Local Truncation Error for the Euler Method
www.cs.unc.edu › ~dm › UNCIn Golub/Ortega's book, it is mentioned that the local truncation error is as opposed to . It is because they implicitly divide it by h. Their derivation of local trunctation error is based on the formula where is the local truncation error. More important than the local truncation error is the global truncation error .

https://qucs.github.io/tech/node25.htmlmethod. For explicit integration methods with the local truncation error yields (6.35) and for implicit integration methods with it is (6.36) Going into equation (6.11) and setting the truncation error is defined as (6.37) With the Taylor series expansions (6.38) (6.39) the local truncation error as defined by eq. (6.37) can be written as (6.40)
