1. The problem statement, all variables and given/known data Let V be a vector space over the field of complex numbers, and suppose there is an isomorphism T of V onto C3. Let a1, a2, a3,a4 be vectors in V such that Ta1 = (1, 0 ,i) Ta2 = (-2, 1+i, 0) Ta3 = (-1, 1, 1) Ta4 = (2^1/2, i, 3) Let W1 be the suubspace spanned by a1 and a2, and let W2 be the subspace spanned by a3 and a4. What is the intersection of W1 and W2? 2. Relevant equations 3. The attempt at a solution In this problem, can we find numerical values for the intersection of the given two subspaces? It's obvious that the intersection would be a line passing through the origin, but given no numerical values of a1,2,3,4 in V, can we find a single vector that spans the line?
