Webbasis for the null space. Notice that we can get these vectors by solving Ux= 0 ﬁrst with t1 = 1,t2 = 0 and then with t1 = 0,t2 = 1. This works in the general case as well: The usual procedure for solv-ing a homogeneous system Ax = 0 results in a basis for the null space. More precisely, to ﬁnd a basis for the null space, begin by ... WebThe orthogonal subspace of S is S ⊥ = { x: x ⋅ v = 0 for all v ∈ S }. So the first step is to find the vectors that are orthogonal to S. Let x be one such vector. Then x ⋅ v is 0. We know one such v; let v = [ 1 1 − 2]. Then x 1 + x 2 − 2 x 3 = 0. The set of vectors that satisfy this expression is a two dimensional subspace.
