Original question and givens

Use V=R^3 and the complete independent ordered column-vector basis basis_w=[[1, 21, 0]] of W. Coordinates are exact integers or [numerator, denominator] pairs with nonzero denominator. Quotient elements are cosets v+W, not unique representative vectors; v+W=u+W iff v−u lies in W. Membership and ranks use the whole subspace, not bounded searches over coefficients. Give (ambient_dimension, dimension_w, quotient_dimension, identity, certificate).

G001 — Use V=R^3 and the complete independent ordered column-vector basis basis_w=[[1, 21, 0]] of W. Coordinates are exact integers or [numerator, denominator] pairs with nonzero denominator. Quotient elements are cosets v+W, not unique representative vectors; v+W=u+W iff v−u lies in W. Membership and ranks use the whole subspace, not bounded searches over coefficients. Give (ambient_dimension, dimension_w, quotient_dimension, identity, certificate).

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.

Expand any ambient vector in the full basis;its W part vanishes in the quotient,so the extension cosets span.If an extension combination belongs to W,it gives a zero relation in the full independent basis,forcing every extension coefficient0.Thus these cosets form a quotient basis,including W=0 and W=V.This is a finite-dimensional formula.
