In this particular case, the solution can be checked by equalling the derivative to zero. It works with this particular function but one has to be very careful with the definitions.
In the code below the way I have made it work.
from sympy import Symbol, lambdify from math import e from scipy.optimize import root_scalar f = Symbol('f') Bnu = 2*h*c**(-2)*(f)**3/(e**(h*(f)/(k*T))-1) DBnu = Bnu.diff(f) lam_DBnu = lambdify(f, DBnu) sol = root_scalar(lam_DBnu, bracket=[c/1000e-9, c/100e-9]) 1e9*c/sol.root
