WitrynaImproved Euler method can be split into two equation, but it should rather be called two steps. You basically perform one Euler step, but this time you call the solution y n + 1 ∗. You then use the average of the slope at y n and y n + 1 ∗ to approximate the slope for your step y n + 1 = y n + h ⋅ s with s = ( f ( y n) + f ( y n + 1 ∗ ... Witryna25 gru 2015 · However, as the step size is decreased, the improved Euler gets closer to the correct answer much more quickly $\endgroup$ – Ben Grossmann Dec 25, 2015 at 4:00 Witryna31 mar 2024 · When you try to plot a line with scalar inputs, the plot doesn't show up in the figure unless you use a Marker like *, +, . etc in chapter for me
