Runge–Kutta methods - Wikipedia
en.wikipedia.org › wiki › Runge–Kutta_methodsIn numerical analysis, the Runge–Kutta methods ( English: / ˈrʊŋəˈkʊtɑː / ( listen) RUUNG-ə-KUUT-tah) are a family of implicit and explicit iterative methods, which include the well-known routine called the Euler Method, used in temporal discretization for the approximate solutions of ordinary differential equations.
Online calculator: Runge–Kutta method
https://planetcalc.com/8400You can use this calculator to solve first-degree differential equation with a given initial value using the Runge-Kutta method AKA classic Runge-Kutta method (because there is a family of Runge-Kutta methods) or RK4 (because it is a fourth-order method). and enter the right side of the equation f (x,y) in the y' field below.

planetcalc.com › 8400The Runge-Kutta method Just like Euler method and Midpoint method, the Runge-Kutta method is a numerical method that starts from an initial point and then takes a short step forward to find the next solution point. The formula to compute the next point is where h is step size and
