With defined field matrix represents f : R^n to R^m, and with region g : [- 1, 1]^{n - 1} for continuous facets, calculate some 2^k steps after.
With randtools meaning, f is described as tan(A * x) == tan(A'' * atan(x)) with invariants. And g is also described as tan x = tan(B t)
A recursive is described as tan(A''^k B t).
