原題與已知條件

同一有限domain上的symbolic rational function tail。操作=pointwise-finite-domain-uniform-max；資料={"limit":[22,23],"coefficients":[23,-24],"shift":2,"epsilon":[1,32]}。請依 [epsilon,pointwise_witnesses,max_N,uniform_on_finite_domain,boundary] 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

逐步推導

same COMPLETE finite domain Fin(2);original aligned limits=[22, 23];signed coefficients=[23, -24];positive shift=2

declared for EVERY n>=0:f_n(x)=limit[x]+coefficient[x]/(n+shift);signed error=f_n(x)-limit[x]=coefficient[x]/(n+shift)

finite-domain witness point0 absolute coefficient cross product := mul(23, 32)

finite-domain witness point0 absolute coefficient cross product = 736

finite-domain witness point0 strict reciprocal threshold := div(736, 1)

finite-domain witness point0 strict reciprocal threshold = 736

finite-domain witness point0 raw strict integer cutoff := sum(736, -2, 1)

finite-domain witness point0 raw strict integer cutoff = 735

finite-domain witness point0:point=0;SIGNED coefficient=23;absolute coefficient=23;positive epsilon=1/32;shift=2

finite-domain witness point0 cutoff denominator := sum(735, 2)

finite-domain witness point0 cutoff denominator = 737

finite-domain witness point0 absolute error at cutoff := div(23, 737)

finite-domain witness point0 absolute error at cutoff = 23/737

finite-domain witness point0 previous denominator := sum(734, 2)

finite-domain witness point0 previous denominator = 736

finite-domain witness point0 previous absolute error := div(23, 736)

finite-domain witness point0 previous absolute error = 1/32

finite-domain witness point0:current N=735;current error=23/737;previous error=1/32;epsilon=1/32

current strict bound holds;previous fails;all smaller indices fail by monotonicity

finite-domain witness point0:declared exact tail;positive denominators increase for all n>=N=735

for EVERY later n,absolute error<=bound=23/737<epsilon=1/32

finite-domain witness point1 absolute coefficient cross product := mul(24, 32)

finite-domain witness point1 absolute coefficient cross product = 768

finite-domain witness point1 strict reciprocal threshold := div(768, 1)

finite-domain witness point1 strict reciprocal threshold = 768

finite-domain witness point1 raw strict integer cutoff := sum(768, -2, 1)

finite-domain witness point1 raw strict integer cutoff = 767

finite-domain witness point1:point=1;SIGNED coefficient=-24;absolute coefficient=24;positive epsilon=1/32;shift=2

threshold=768;floor=768;least nonnegative strict cutoff N=767

finite-domain witness point1 cutoff denominator := sum(767, 2)

finite-domain witness point1 cutoff denominator = 769

finite-domain witness point1 absolute error at cutoff := div(24, 769)

finite-domain witness point1 absolute error at cutoff = 24/769

finite-domain witness point1 previous denominator := sum(766, 2)

finite-domain witness point1 previous denominator = 768

finite-domain witness point1 previous absolute error := div(24, 768)

finite-domain witness point1 previous absolute error = 1/32

finite-domain witness point1:current N=767;current error=24/769;previous error=1/32;epsilon=1/32

current strict bound holds;previous fails;all smaller indices fail by monotonicity

finite-domain witness point1:declared exact tail;positive denominators increase for all n>=N=767

for EVERY later n,absolute error<=bound=24/769<epsilon=1/32

finite-domain maximum witness denominator := sum(767, 2)

finite-domain maximum witness denominator = 769

finite-domain maximum absolute error point0 := div(23, 769)

finite-domain maximum absolute error point0 = 23/769

finite-domain maximum absolute error point1 := div(24, 769)

finite-domain maximum absolute error point1 = 24/769

positive epsilon=1/32;ALL pointwise witness rows=[[0, 735], [1, 767]];finite domain size=2

finite maximum N=767;all point errors at common N=[23/769, 24/769];same N works for every point and every later n
