0 = (x^2 - 6.00000000000000)*x^2 - 4*x*(e^(2/5*I*pi) + e^(-2/5*I*pi)) - e^(4/5*I*pi) - e^(-4/5*I*pi) - 1

x + x^(1/3) == -2 ?

tanh(ax) = x
numerically.
But the problem is sage gives option of finding just one root provided I give it the interval where the root may be found.
(tanh(1.5*x)==x).find_root(0.5,2)
But sometimes the interval is not so obvious and I need to know all the numerical roots at once
(If the number of roots are finite that is). Is There a way to do that?
