Given $x^k \in \mathbb R^n$, which is our current best estimate of a root for $g$, we would ideally like to find a vector $\Delta x$ such that $g (x^k + \Delta x) = 0$. But that is too difficult, so we instead compute a vector $\Delta x$ which satisfies $g (x^k) + g' (x^k)\Delta x = 0$. slow shipping
