Linear combination theorem

Nettetminimum positive linear combination. Lemma 6. If a and b are not both zero, then the least positive linear combination is a common divisor of a and b. Proof. Let m = ua + vb be the least positive linear combination. Using the quotient-remainder theorem we can write a = qm+ r where 0 r < m. Observe that r = a qm = a q(ua+ vb) = (1 qu)a+ ( qv)b: Netteta Linear Combination of ~x 1;:::;~x ... Theorem about Spans Theorem Given X ˆV the set Span(X) is a subspace. It follows that Span(X) is the smallest subspace of V containing X. Proof: We must check the three subspace conditions 1 ~0 is by convention equal to the empty sum, and so is a linear combination.
