WebApr 18, 2024 · Newton's method for root finding can be derived as follows. 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 $g (x^k) + g' (x^k)\Delta x = 0$. http://spiff.rit.edu/classes/phys317/lectures/open_root/open_root.html trump\u0027s cabinet confirmed healthWebMar 23, 2024 · The Newton part seems to be OK. @flow_me_over, thank you so much for confirming that the NR at least seems okay!
