y'' + 2y' + 2y = cos(2x) y(0) = 0 y'(0) = 0
To the left you see the code for a Python program solving this differential equation numerically and drawing the graph.
The function odeint from the library scipy.integrate solve this differential equation.
odeint has three parameters:
model : function call where you have the mathematical model in the diff.eq.
y0 : initial value [y(0)=0, y'(0)=0]
t : time array
The two first parameters (model and y0) are transferred to the first parameter y in the model function.
The body part (line 19-34) of model contains the mathematical model of the diff.eq.
