In general, it’s not a good idea. And in general, Newton’s method won’t converge. Newton’s method boils down to replacing your function by a first-order approximation. For a differentiable function, in a small neighbourhood(!), that’s a goo

The Wall Street Journal is a very, very good newspaper that brought us such amazing series as "What They Know", which I believe started the practice of referring to the use of trackers as "spying" (much to the dismay of
