WebShow that the set is linearly dependent by finding a nontrivial linear combination of vectors in the set whose sum is the zero vector. (Use S₁, S2, and S3, respectively, for the vectors in the set.) S = { (5, 4), (-1, 1), (4, 0)} (0, 0) = Express the vector s₁ in the set as a linear combination of the vectors S2 and S3. S1 = WebSep 9, 2024 · 0. Your vectors e 1, e 2, e 3 are not linearly independent (check the determinant of your matrix, without the extra column) You will only have a linear combination a e 1 + b e 2 + c e 3 = v whenever v ∈< e 1, e 2, e 3 >, which is not the case here. If your vectors were linearly independent, then d i m ( < e 1, e 2, e 3 >) = 3, …
