Scipy resolver ecuación numéricamente
>>> from scipy.optimize import fsolve
>>> def func(x):
... return [x[0] * np.cos(x[1]) - 4,
... x[1] * x[0] - x[1] - 5]
>>> root = fsolve(func, [1, 1])
>>> root
array([6.50409711, 0.90841421])
>>> np.isclose(func(root), [0.0, 0.0]) # func(root) should be almost 0.0.
array([ True, True])
