Sep 30, 2017 · Unlike the Euler Method solution in Lesson 14, which crossed the equilibrium solution, the Improved Euler's Method solution does not approach the equilibrium solution fast enough. To obtain a reasonable approximation on the entire interval using the Improved Euler's Method, a smaller stepsize is required.

May 17, 2015 · To improve the approximation, we use the improved Euler’s method.The improved method, we use the average of the values at the initially given point and the new point. We define the integral with a trapezoid instead of a rectangle. The trapezoid has more area covered than the rectangle area. It will also provide a more accurate approximation.

Improved Euler Formula. A better approximation method can be obtained if the integrand in Eq. is approximated more accurately. One way to do this is to replace the integrand by the average of its values at the two endpoints, namely, . This is equivalent to approximating the area under the curve between and by the area of the shaded trapezoid
