Given a collection x1, x2, …, xk of vectors in ℝn, we say that the vectors form a linearly dependent set if one of them can be written as a linear combination of the others. That is, the set is linearly dependent if there is an index j in the range 1 to k such that

where the ci’s are given numbers.

Show that any set of vectors containing 0 is linearly dependent.
