Two vectors are dependent iff at least one is a scalar multiple of the other

Created almost 9 years ago, updated about 8 hours ago

Two vectors form a dependent list iff at least one is a scalar multiple of the other. If both are nonzero, either is a multiple of the other. If one is zero, it is the zero multiple of the other. For nonzero vectors, independence means neither is a multiple of the other. The original statement with “dependent iff neither” reversed the conclusion.
