than like this?
z = a + R * sp.exp(sp.I * t)
f_at_a = 1 / (2 * sp.pi * sp.I) * sp.Integral(
f(z) / (z - a) * sp.diff(z, t),
(t, 0, 2 * sp.pi),
)
The heiroglyphs let me offload some of the work to my vision system. It feels like there's some kind of hierarchical attention organization mechanism that works better in visual space. If I'm not pushing to "maximum math," both representations clear the hurdle of "good enough" (CIF does) but if I'm trying to chew through something genuinely gnarly I want all the help I can get.
