3.1 Second-Order Runge-Kutta Methods As always we consider the general first-order ODE system y0(t) = f(t,y(t)). (42) Since we want to construct a second-order method, we start with the Taylor expansion y(t+h) = y(t)+hy0(t)+ h2 2 y00(t)+O(h3). The first derivative can be replaced by the right-hand side of the differential equation

In numerical analysis, the Runge–Kutta methods 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. These methods were developed around 1900 by the German mathematicians Carl Runge and Wilhelm Kutta.

29.10.2019 · This is my function I am calling into my Runge-Kutta function. It is a second order ODE. I need my Runge-Kutta to be able to accept it, but I am not sure how. I tried altering how the inputs to the equation are formatted but nothing has worked. Here is the Runge-Kutta code.
