The Runge-Kutta Method is a numerical technique used to solve ordinary differential equations. It provides an approximate solution by evaluating the function at several points within each step, allowing for greater accuracy than simpler methods like Euler's method. The most common version, known as RK4, uses four evaluations per step to calculate the next value. This method is widely used in various fields, including physics and engineering, due to its balance between computational efficiency and accuracy. It is particularly useful for problems where analytical solutions are difficult or impossible to obtain.
