EXAMPLE: Finding a basis for a subspace defined by a linear

WebTo get a basis for the space, for each parameter, set that parameter equal to 1 and the other parameters equal to 0 to obtain a vector. Each parameter gives you a vector. So setting r = 1 and s = t = 0 gives you one vector; setting s = 1 and r = t = 0 gives you a second vector; setting t = 1 and r = s = 0 gives you a third. WebLet W be the subspace spanned by the given vectors. Find a basis for W ⊥ . v 1 = ( 2, 1, − 2); v 2 = ( 4, 0, 1) Well I did the following to find the basis.

WebJul 18, 2024 · To show that W is a subspace, simply note that if p, q ∈ W, then ( p + q) ( − x) = p ( − x) + q ( − x) = p ( x) + q ( x) = ( p + q) ( x). Similarly, ( k p) ( − x) = k ( p ( − x)) = k ( p ( x)) = ( k p) ( x) for all scalars k. Hence, W is a subspace. WebJan 2, 2024 · The first step is to find an homogeneous system s.t the subspace is the solution set (Null space).
