Euler法和改进的Euler法相比较，改进Euler法的计算精度更高，相对误差也比较小。因此在求解微分方程的数值解时，改进的Euler法优于Euler法。-Euler method and the improved Euler wears comparison, higher accuracy improved Euler method, the relative error is relatively small. Therefore, in the numerical solution of differential equations, Euler method is superior to the improved Euler method.
