set of vectors {v1, v2.......,vn} belongs to R^m where n<m. are vectors independent?
not necesarily. for instance \[ \large \{(1,2,3),(0,0,0)\} \] is a linearly dependent set of two vectors in \(\mathbb{R}^3\) and \(2<3\).
since you can prove that, for at least one case this is not true, therefore it can not be generalized.
To prove that (1,2,3) and (0,0,0) are dependent: Let us assume the contrary. If they are independent, then k1* (1,2,3) + k2 * (0,0,0) = (0,0,0) implies k1 = k2 = 0. But, in this case, only k1 has to be 0. k2 can be any number and the expression still holds. Hence the proof.
