Chapter 3, Problem 7(choose chapter or problem)
We saw in Exercise 2.5.13 that if the \(m \times n\) matrix A has rank 1, then there are nonzero vectors \(\mathbf{u} \in \mathbb{R}^{m} \text { and } \mathbf{v} \in \mathbb{R}^{n}\) such that \(A=\mathbf{u v}^{\top}\). Describe the four fundamental subspaces of A in terms of u and v. (Hint: What are the columns of \(\mathbf{u v}^{\mathrm{T}}\)?)
