For three-dimensional vectors $u, v, w$, the scalar triple product $u\cdot(v\times w)$ is equal to the determinant of the matrix formed by placing these vectors as columns, denoted as $\det[u\ v\ w]$.

Conditions: The vectors $u, v, w$ are three-dimensional.; The vectors are arranged as columns in the matrix.
