Solving second order differential equation in python YouTube
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,

differential equations solve in python
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:

solve_ivp returns an object from which v ( t) (and other results) can be found, while ode_int returns v ( t). For this single first-order equation, v ( t) is returned for the N requested t points as a 1 × N two-dimensional array by solve_ivp and as a N × 1 array by odeint. odeint has no choice of solver while the solve_ivp solver can be set.

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.

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 ).
