Original question and givens

On all R, f(x)=14. Use the scoped signed polynomial moments to find I(f,2,17), with oriented endpoints. Give a reduced fraction with positive denominator, retaining /1 for integers.

  • G001 — On all R, f(x)=14. Use the scoped signed polynomial moments to find I(f,2,17), with oriented endpoints. Give a reduced fraction with positive denominator, retaining /1 for integers.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

S001 · implies

Before

source roles = [qf-integral-constant, constant_integral, reals, []]

After

derived = [[signed_moment_fraction_RETAIN1]]

Conditions: none

Legacy banks enforce their exact source keys/operation/domain.BASE integers retain metadata without treating it as an oracle.Distinguish NUMBER,string,fraction pair and vector equality formats;retain original bilingual data/AST/status.

Step identifiers and dependencies

Rule: R64_SOURCE_exact_legacy_interface_BASE_metadata_AND_output_roles · Uses: G001

S002 · calculation

Before

Constant moment ORIGINAL oriented width := sub(17, 2)

After

Constant moment ORIGINAL oriented width = 15

Conditions: none

Use ORIGINAL operands/order for exact integer/rational arithmetic.RAW bounds are bank-specific;derived values are not SAFE-recapped or approximated.Do not import legacy caps into BASE integers.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S001

S003 · calculation

Before

Constant moment ORIGINAL c times oriented width := mul(14, 15)

After

Constant moment ORIGINAL c times oriented width = 210

Conditions: none

Use ORIGINAL operands/order for exact integer/rational arithmetic.RAW bounds are bank-specific;derived values are not SAFE-recapped or approximated.Do not import legacy caps into BASE integers.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · implies

Before

source roles = [14, 2, 17]

After

derived = [15, 210/1]

Conditions: none

The signed constant moment c(b−a)retains orientation,reverses sign with endpoints,and vanishes at equal endpoints.It is not automatically nonnegative area;integer answers retain/1.

Reverse checks

  • S004 · premise_and_result_audit — Reverse-check ORIGINAL data,field roles,types,domain and premises;the conclusion need not uniquely recover its premises.Keep source-bound candidates,independent review,formal proof and publication separate.
  • S003 · premise_and_result_audit — Recompute Constant moment ORIGINAL c times oriented width with exact rational arithmetic, not rounded decimals.
  • S002 · premise_and_result_audit — Recompute Constant moment ORIGINAL oriented width with exact rational arithmetic, not rounded decimals.
  • S001 · premise_and_result_audit — Reverse-check ORIGINAL data,field roles,types,domain and premises;the conclusion need not uniquely recover its premises.Keep source-bound candidates,independent review,formal proof and publication separate.

Result

210/1

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
