Modified Euler's Method : The Euler forward scheme may be very easy to implement but it can't give accurate solutions. A very small step size is required for any meaningful result. In this scheme, since, the starting point of each sub-interval is …

Aug 31, 2021 · Given equation dy/dx = x + y. Here f (x, y) = x + y with y (0) = 1. Take h = 0.05 – 0 = 0.05. By modified Euler’s formula the initial iteration is. The iteration formula by modified Euler’s method is. For n=0 in equation (i) we get. Where as above. For n=1 in equation (i) we get. For n=3 in equation (i) we get.

For the modified Euler method, point B is a provisional point. The modified Euler method evaluates the slope of the tangent at B, as shown, and averages it with the slope of the tangent at A to determine the slope of the improved step. Averaging is an improvement because the slope at B is too shallow while the slope at A is too steep.

It works first by approximating a value to yi+1and then improving it by making use of average slope. yi+1. = yi+ h/2 (y'i+ y'i+1) = yi+ h/2(f(xi, yi) + f(xi+1,yi+1)) If Euler's method is used to find the first approximationof yi+1then. yi+1 = yi+ 0.5h(fi +f(xi+1, yi + hfi)) Truncation error:

Example 3.2.2 ... y=e−2x4(x4+4). The results obtained by the improved Euler method with h=0.1 are better than those obtained by Euler's method ...

Modified Euler method is another numerical method to solve the first order ordinary differential equation with given initial condition. This method is better compare to Simple Euler method. Because this method take an arithmetic average of slopes at xi and xi+1, mean, at the end points of each sub-interval. In this, we compute first approximation […]
