A set of non-zero vectors {→u1, ⋯, →uk} in Rn is said to be linearly independent if whenever k ∑ i = 1ai→ui = →0 it follows that each ai = 0. Note also that we require all vectors to be non-zero to form a linearly independent set.
WebSo c1 must be equal to 0. And c2 is equal to 0/7 minus 2/21 times 0. So c2 must also be equal to 0. So the only solution to this was settings both of these guys equal to 0. So S is also a linearly independent set. So it spans r2, it's linearly independent. So we can say definitively, that S-- that the set S, the set of vectors S is a basis for r2. WebDetermine which of these sets form a basis of R3. For those sets which are not bases, state whether they do not span R3, are not linearly 1. independent, or both: 8 <: 2 4 1 2 0 …
