Given two vectors → v1 and → v2 in a vector … Webregardless of what value of a we choose, so your given spanning set is linearly dependent. Indeed, setting a = 1, this means that [ 1, 3, 3] = 2 [ 0, 0, 1] + [ 1, 3, 1], so the first vector is unnecessary to span the whole space, since it's a linear combination of the other two vectors. In particular,
