This program implements Runge Kutta (RK) fourth order method for solving ordinary differential equation in Python programming language. Output of this Python program is solution for dy/dx = x + y with initial condition y = 1 for x = 0 i.e. y (0) = 1 and we are trying to evaluate this differential equation at y = 1 using RK4 method ( Here y = 1 ...
13.09.2018 · Show activity on this post. I am trying to do a simple example of the harmonic oscillator, which will be solved by Runge-Kutta 4th order method. The second-order ordinary differential equation (ODE) to be solved and the initial conditions are: y'' + y = 0. y (0) = 0 and y' (0) = 1/pi. The range is between 0 and 1 and there are 100 steps.
