12. Runge–Kutta Methods (RK2, RK4)
The chapter delves into the Taylor Series Method, a numerical technique for solving first-order ordinary differential equations (ODEs) when analytical solutions are difficult to obtain. It involves expanding functions into an infinite series to approximate values at various points, detailing its advantages, disadvantages, and practical applications in engineering and scientific contexts. The method is foundational for more advanced techniques, despite its computational complexities.
