Question: An anthropologist studying ritualistic circular dance formations interprets rhythmic movements as vectors; find the vector $ \mathbfv = \langle x, y, z \rangle $ satisfying $ \mathbfv \times \langle 1, 2, 3 \rangle = \langle 1, -2, 1 \rangle $ and $ \mathbfv \cdot \langle 1, 2, 3 \rangle = 0 $. - go-checkin.com
