I misread your function.

   (^~ - +:) Newton 1.1
0.346323j1.2326e_32
   (^~ - +:) Newton 0.5
0.346323

Still need those guardrails!

In "Fifty Shades of J" chapter 23, the Newton Raphson algorithm is
described thusly:

Newton =: adverb : ']-u%(u D.1)'(^:_)("0)

How would that be defined using the new derivative verbs?

Also, what is the replacement for d.?

How would I find the roots of (x^x)=2*x using Newton Raphson?
