1. Let W1 and W2 be subspaces of a vector space V over K, and let S, be a subset of W1
and S2 a subset of W2. Show that if S1 spans W1 and S2 spans W2, then S1U S2 spans
W1 +W2.
2. In R', let S =
U = sp(S) and W = sp(T). Find a basis for U + W and determine the dimension of
{(1,2, 2, – 1), (0, – 1, 4, 2)} and T
{(2, 5, 0, –4), (0, 2, –8, 3)}, and let
UnW.
