1.7 Linear Independence De nitionMatrix ColumnsSpecial Cases Special Cases: 1. A Set of One Vector Sometimes we can determine linear independence of a set with minimal e ort. Example (1. A Set of One Vector) Consider the set containing one nonzero vector: fv 1g The only solution to x 1v 1 = 0 is x 1 = : So fv 1gis linearly independent when v 1 ...
