python Using 4th order Runge Kutta to solve the 2nd order differential equation of a damped
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 ร N two-dimensional array by solve_ivp and as a N ร 1 array by odeint. odeint has no choice of solver while the solve_ivp solver can be set.

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.

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.
Solving second order differential equation in python YouTube
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] = หz x [ 1] = z ห and x[0] =z x [ 0] = z. In that case, or original second-order equation can be expressed as:
