10. Modified Euler’s Method

10. Modified Euler’s Method

Modified Euler's Method is a numerical technique designed to provide improved accuracy in solving first-order ordinary differential equations (ODEs) where analytical solutions may not be viable. It enhances the standard Euler's Method by considering averages of slopes, thus yielding more precise approximations. While simpler and more efficient than higher-order methods like Runge-Kutta, it remains computationally lightweight, making it suitable for various engineering applications.
