The "next-level math trick" Newton-Raphson has nothing to do with
functional programming. I have written solvers in purely iterative
style. As far as I know, Newton-Raphson is the opposite of functional
programming as you iteratively solve for the root. Functional programming
is stateless where you are not allowed to store any state (current best
guess root).
