In the fixed basis of the real plane R², u=(-5, 0) and v=(-4, -1). Are u and v equal?
G001 — In the fixed basis of the real plane R², u=(-5, 0) and v=(-4, -1). Are u and v equal?
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.
source roles = [qf-vector-coordinate-equality, [domain, operation, u, v]]
After
derived = [vector, vector_equality, reals]
Conditions: none
Use THIS bank’s actual fields,operation/domain and types.BASE retains permissible extra metadata.Do not import LDL SAFE/set limits or a different bank’s deduplication rules.
derived = [two real coordinates in ONE ordered basis]
Conditions: none
The vectors use ONE ordered basis.Type ALL TWO RAW SAFE components and k.These are vector coordinates,not points,lengths or a dot product.Component sums alone do not determine equality.

Result
No
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.

Review date: 2026-10-26
Original questions, answers, step expressions, numeric ASTs and historical records are retained. Source candidate labels remain historical and are not overwritten as formal proof.
