Mixing solutions of sympy equation

I’m solving an time depend equation that has the following form (finding the roots for \lambda): import sympy as sp import matplotlib.pyplot as plt t = sp.symbols(r’t’, real=True, positive=True) eq = … print(repr(eq)) -\lambda**3 – 2*\lambda**2*t + 4*\lambda*t**4 – 8*\lambda*t**3 + 8*\lambda*t**2 – 8*\lambda*t + 4*\lambda + 8*t**3 – 16*t**2 + 8*t Solving the equation… Read More Mixing solutions of sympy equation
