Hello
Is it possible to solve this differential equation using sympy?
z'' + c * z = -sign(z')
I tried to solve it and got the following error:

I tried to solve it and got the following error:
Error:No algorithms are implemented to solve equation _Dummy_39 + x(t) + sign(_X0)
Code:import sympy as sp import numpy as np sp.init_printing() t = sp.symbols('t') x = sp.Function('x')(t) x_dot = x.diff(t) x_two_dot = (x.diff(t)).diff(t) expr = sp.Eq(x_two_dot, -sp.sign(x_dot) -x ) sol = sp.dsolve(expr); solThanks for your helps
