Question: A micropaleontologist applies Fourier-like decomposition to periodic microfossil abundance data, solving $\mathbfv \times \mathbfu = \mathbfw$, where $\mathbfu = \langle 1, 2, 3 \rangle$, $\mathbfw = \langle 4, -2, 1 \rangle$. If $\mathbfv = \langle a, b, c \rangle$, determine the rank of the homogeneous system arising from the cross product. - go-checkin.com
