WitrynaBowen. 10 years ago. [1,1,4] and [1,4,1] are linearly independent and they span the column space, therefore they form a valid basis for the column space. [1,2,3] and [1,1,4] are chosen in this video because they happen to be the first two columns of matrix A. The order of the column vectors can be rearranged without creating much harm here. Witryna$\forall \mathbf v \in \map {\mathrm N} {\mathbf A}, \lambda \in \R: \lambda \mathbf v \in \map {\mathrm N} {\mathbf A}$, from Null Space Closed under Scalar Multiplication. The result follows from Vector Subspace of Real Vector Space. $\blacksquare$ Sources. For a video presentation of the contents of this page, visit the Khan Academy.
