https://www.pythonlore.com/solving-nonlinear-equations-with-scipy-optimize-fsolve/
WEBJan 11, 2024 · The basic usage of fsolve requires two main arguments: the function that defines the nonlinear equation (s) and an initial guess for the roots. The syntax looks like this: from scipy.optimize import fsolve. # Define the function whose roots we want to find. def func(x): return x**2 - 2. # Provide an initial guess. initial_guess = 1. # Call fsolve.
