Problem 5 (Intersections and unions of subspaces) Let V be a vector space. Let U and W be subspaces of V. 1. Show that the intersection UnW is a subspace of V. 2. Show that the union UUW is a subspace of V if and only if either UCW or W CU. Hint 1: Try a proof by contradiction. Hint 2: Think about the intersection of two non-parallel planes (passing through the origin) in R³ before tackling the general statement.
