Newton's backward difference formula
Witryna26 lip 2024 · The backward Euler method is derived from the simple backward difference expression for the derivative, y ′ = ( y n − y n − 1) / h. The backward Euler method is an iterative method which starts at an initial point and walks the solution forward using the iteration y n + 1 − h f ( t n + 1, y n + 1) = y n. WitrynaTo simplify this when the xj are equally spaced, it is convenient to introduce the backward difference operator ∇, for which. and ∇ n+ 1fi = ∇ (∇ nfi ), as for forward differences. Proceeding as we did in deriving the forward difference formula, we obtain from (4.35) (4.36) This is the backward difference formula.

WitrynaNewton's formula is of interest because it is the straightforward and natural differences-version of Taylor's polynomial. Taylor's polynomial tells where a function will go, based on its y value, and its derivatives (its rate of change, and the rate of change of its rate of change, etc.) at one particular x value. Newton's formula is Taylor's polynomial …

They are linear multistep methods that, for a given function and time, approximate the derivative of that function using information from already computed time points, thereby increasing the accuracy of the approximation. These methods are especially used for the solution of stiff differential equations.
