Is it possible to find a pair of two dimensional subspaces U and V of R^3 such that U intersection V = {0}? Prove your answer. Give a geometricle interpretation of your conclusion. [ hint: let {u_1,u_2} and {v_1,v_2} be bases for U and V, respectively. Show that u_1,u_2,v_1,v_2 are linearly independent.]

Best ResponseYou've already chosen the best response.1Well, a twodimensional subspace of \(\mathbb{R}^3\) is a plane, right?

Best ResponseYou've already chosen the best response.0um not always, you could have a two dim subspace with 2 linear independent vectors and span a line

Best ResponseYou've already chosen the best response.1That's right; you could span two lines that intersect at the origin.
