Solving 2nd order ODE with python Ask Question Asked 6 years, 7 months ago Modified 12 months ago Viewed 6k times 0 I was writing some code to solve 2nd order differential equation, but it gives a completely wrong result. I think that the problem is in expressing Euler method in the right way.

differential equations solve in python

Netwon's second law, F=ma, is naturally a second order differential equation as the acceleration is a second derivative of the position, x. Last week, we solved Newton's Second Law for the special case where the force was either a constant or a function of the velocity. In that case, we could solve Newton's second law as a first order.

-1 I have been given two second order ODEs and I've been asked to solve them with odeint in python. These are the equations: d^x (t)/dt^2 = 10dy (t)/dt + x (t) - (k + 1) (x (t))/z^3 d^2y (t)/dt^2 = - 10dy (t)/dt + y (t) - ( (k+1) (y (t) + k))/z^3 where z = np.sqrt ( (y+k)^2+x^2))

Problems in a complex domain can be solved as well. In this case, y and p are considered to be complex, and f and bc are assumed to be complex-valued functions, but x stays real. Note that f and bc must be complex differentiable (satisfy Cauchy-Riemann equations ), otherwise you should rewrite your problem for real and imaginary parts.

This equation is in the form of a first-order differential equation in S S. Essentially, what we have done is turn an nth n t h order ODE into n n first order ODEs that are coupled together, meaning they share the same terms. TRY IT! Reduce the second order pendulum equation to first order, where. S(t) = [Θ(t) Θ˙(t)]. S ( t) = [ Θ ( t) Θ.

Python I was going through my ODE notes the other day and wondered if I could solve any of them with Python. I gave it a shot for one of the simpler equations, and here are my results (with analytic solution included for comparison). Problem Say we have the equation y′′ +y′ + 2y = 0, y ″ + y ′ + 2 y = 0,

The strategy to solve a second-order differential equation using odeint () is to write the equation as a system of two first-order equations. This is achieved by first writing x[1] = ˙z x [ 1] = z ˙ and x[0] =z x [ 0] = z. In that case, or original second-order equation can be expressed as:

A (x) y'' (x)^2 + B (x) y (x) + C (x) = 0, y' (0) = a, y (0) = b What I usually do in this type of cases is to ask Mathematica to solve it. And she usually solve it. But, sometimes mathematica show some error, for instance "singularity or stiffness at x=d". Now, I am trying to solve them in some basic language ( read python ).
