if u v and w are vectors that are linearly independent will u-v v-w and u-w be linearly independent?
i believe they are dependent if the Wronskian is zero.
recall that a set of two or more vectors is linearly dependent if and only if at least one of the vectors in the set can be expressed as the linear combination of finitely many other vectors in the set.
now, note that:
and
so we see that each of the vectors can be expressed as a linear combination of the other two, thus the vectors u - v, v - w, and u - w form a linearly dependent set of vectors
