Web3.4.1 Backward Euler We would like a method with a nice absolute stability region so that we can take a large teven when the problem is sti . Such a method is backward Euler. It can be derived like forward Euler, but with Taylor expansions about t= t n. This leads to: y n= y n 1 + t nf(t n;y n). Note 4. This is a rst-order method.(verify) WebApr 19, 2016 · For backwards Euler, all you are doing is using the slope at the end of your line approximation rather than the start of it. As to why you would want to do this, it is a more complicated answer involving the stability of your solution.

WebFor the forward Euler method, the LTE is O(h 2). Hence, the method is referred to as a first order technique. In general, a method with O(h k+1) LTE is said to be of kth order. Evidently, higher order techniques provide lower LTE for the same step size.
