Hello, I have the following script .
import sympy as sym i, r1, c1, r2, c2, t = sym.symbols('i, r1, c1, r2, c2, t' ) x1 = sym.Function('x1') x2 = sym.Function('x2') eq1 = r1*c1*sym.Derivative(x1(t),t) + x1(t) - x2(t) - r1*i eq2 = r2*c1*sym.Derivative(x1(t),t) + r2*c2*sym.Derivative(x2(t),t) + x2(t) - r2*i sol=sym.dsolve((eq1, eq2)) print(sol) If I run this I have an error : TypeError: cannot determine truth value of Relational Someone can help me please ?
