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

source operation=improper-interior-singular-split;original snapshot and mathematics retained

explicit ordered source output fields=[interval, singularity, left_integrand, right_integrand, left_integral, right_integral, left_converges, right_converges, sum, certificate]

Improper LEFT reduced exponent numerator gap := sub(1, 0)

Improper LEFT reduced exponent numerator gap = 1

Improper LEFT reciprocal of one minus exponent := div(1, 1)

Improper LEFT reciprocal of one minus exponent = 1

Improper LEFT scale times singular-side integral := mul(17, 1)

Improper LEFT scale times singular-side integral = 17

ORIGINAL LEFT side at c=4;scale=17;REDUCED exponent=0/1 in[0,1)

put distance t>0 from c;integral_delta^1 scale*t^(-exponent)=scale/(1-exponent)*(1-delta^(1-exponent));positive1-exponent makes delta term vanish,side limit=17

Improper RIGHT reduced exponent numerator gap := sub(2, 1)

Improper RIGHT reduced exponent numerator gap = 1

Improper RIGHT reciprocal of one minus exponent := div(2, 1)

Improper RIGHT reciprocal of one minus exponent = 2

Improper RIGHT scale times singular-side integral := mul(18, 2)

Improper RIGHT scale times singular-side integral = 36

ORIGINAL RIGHT side at c=4;scale=18;REDUCED exponent=1/2 in[0,1)

put distance t>0 from c;integral_delta^1 scale*t^(-exponent)=scale/(1-exponent)*(1-delta^(1-exponent));positive1-exponent makes delta term vanish,side limit=36

Improper independent singular-side limits sum := sum(17, 36)

Improper independent singular-side limits sum = 53
